Description

Technical Field

[0001] This disclosure relates to printed matter, display devices using the printed matter, solar cells using the printed matter, and solar cell systems using the printed matter. Background Technology

[0002] Conventionally, methods for applying various designs such as text, graphics, patterns, and colors to articles include coating or printing to form a film on the surface of a substrate. For example, to give a sense of luxury, dashboards in automobile interiors sometimes use dashboards with wood grain patterns. For manufacturing materials with wood grain patterns, coating methods have been disclosed (for example, see Patent Document 1). Additionally, for manufacturing materials with wood grain patterns, printing methods have been disclosed (for example, see Patent Document 2).

[0005] Patent Document 1: Japanese Patent Application Publication No. 2013-158746

[0006] Patent Document 2: Japanese Patent Application Publication No. 2000-185455 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] In the coated material of Patent Document 1 and the printed material of Patent Document 2, the surface of the substrate is covered by a coating or ink film to suppress light transmission. Therefore, for example, in order to display visual information on a dashboard to provide various information about the vehicle, it is necessary to provide an information display section, such as a display screen or LED display section, in addition to the wood grain pattern. From a design or cost perspective, it is sometimes desirable to display visual information directly on a dashboard or similar surface with a wood grain pattern. Therefore, light emitted from a light-emitting device located on the back side of the dashboard or similar surface needs to pass through the decorative layer forming the wood grain pattern to reach the user's eyes.

[0009] In addition, coatings or printing are sometimes used to form a film on the surface of a substrate to impart various functions such as design or waterproofing. For example, to impart design or waterproofing, a decorative layer is sometimes formed on the surface of a solar cell facing the light source by means of a coating. If the entire solar cell is covered by a decorative layer and light is suppressed, the function of the solar cell is reduced. Even when a decorative layer is formed on the surface of the solar cell, it is still necessary for light to pass through the decorative layer to reach the solar cell. That is, sometimes even when a decorative layer is formed to impart design or various functions to an item, it is desirable for light to pass through the decorative layer.

[0010] The present disclosure addresses the aforementioned issues and aims to provide printed materials, display devices, solar cells, and solar cell systems that allow light to pass through the printed layer even when the printed layer is used as a decorative layer to impart design or various functions.

[0011] Solution for solving the problem

[0012] The printed matter disclosed herein includes: a printed layer having ink portions composed of printed ink and forming a plurality of apertures for light to pass through; and a substrate having the printed layer printed on its surface, wherein the plurality of apertures are each composed of micropores that are difficult to be visually identified by the naked eye.

[0013] The display device disclosed herein includes: a printed material with the above-described structure; and a light-emitting device disposed on the back side of the printed material, wherein the printed material constitutes a display panel, and light emitted by the light-emitting device and transmitted through a plurality of holes from the back side displays text, graphics, symbols, or images on the display section.

[0014] The solar cell disclosed herein is a printed material with the above-described structure. The substrate includes a power generation layer, which is stacked with the printed layer. Power generation is achieved by transmitting light through a plurality of apertures in the printed layer. The printed layer is printed on the light-receiving side of the power generation layer.

[0015] The solar cell system disclosed herein includes: a printed material with the above-described structure, the printed material being disposed on a light-receiving side; and a solar cell, the solar cell being disposed facing the printed material and generating electricity by transmitting light through a plurality of holes in the printed material, the substrate being composed of a transparent substrate having a light-transmitting transparent component and a printed layer printed on its surface.

[0016] The effects of the invention

[0017] According to this disclosure, the printed material includes: a printed layer having ink portions composed of printed ink and forming a plurality of apertures for light to pass through; and a substrate having the printed layer printed on its surface. The plurality of apertures are each composed of micropores that are difficult to see with the naked eye. Even when the ink portions of the printed layer form a decorative layer for design purposes or various functions, light can still pass through the printed layer through the plurality of apertures.

[0047] Implementation Method 1

[0048] [100 printed materials]

[0049] Figure 1 This is a top view showing an example of the printed material 100 of Embodiment 1. Figure 2 This is a conceptual diagram showing an example of a cross-section of the printed material 100 according to Embodiment 1. (See diagram below.) Figure 1 As shown, printed matter 100 is an article on which printing has been applied to its surface.

[0050] Printed materials 100 can be, for example, a car dashboard or a solar cell, but any item that is printed can be used, and is not limited to dashboards. Furthermore, by applying printing, the appearance and texture of an item can be altered, for example, by adding design or functional value to its exterior.

[0051] like Figure 2 As shown, the printed material 100 of Embodiment 1 includes a printing layer 110 and a substrate 120. Furthermore, in Figure 2 In this process, the printing layer 110 consists of a single layer, but it can also consist of multiple layers. The printed material 100, through the ink portions 111 (described later) of the printing layer 110, forms a decorative layer to which various designs such as text, graphics, patterns, images, and color separations are applied. Furthermore, the printed material 100 can also, through the ink portions 111 (described later) of the printing layer 110, form a decorative layer with various functions such as water resistance, hydrophobicity, stain resistance, antibacterial properties, or rust prevention.

[0052] Figure 3 This refers to the printed material 100 representing Embodiment 1. Figure 1 A partial enlarged view of an example of an enlarged view of part A. Figure 4 yes Figure 3 Sectional view along line B-B. Figure 5 This refers to the printed material 100 representing Embodiment 1. Figure 1 Another example of a magnified view of part A. Figure 6 yes Figure 5 The B-B line sectional view. In addition, part A is a part defined to illustrate the enlarged shape of the printed layer 110, and the position of part A is not limited to the position shown in the figure, and may be in other positions.

[0053] like Figures 3-6 As shown, the printing layer 110 has an ink portion 111 composed of printed ink and has a plurality of apertures 112 through which light passes. The printing layer 110 includes the ink portion 111 and the plurality of apertures 112.

[0054] Ink portion 111 is a portion of the printed layer 110 in which ink is disposed. Ink portion 111 is, for example, a halftone dot. Ink portion 111 is a portion formed by placing printed ink on the substrate 120. Ink portion 111 is a portion in which an ink film is formed relative to the substrate 120. The halftone dots of ink portion 111 are arranged irregularly, for example, in the printed matter 100. The halftone dots of ink portion 111 may also be arranged regularly in the printed matter 100, but an irregular arrangement is preferred.

[0055] The ink layer 111 and the printing layer 110 are formed by printing. For example... Figure 3 As shown, the ink section 111 can be constructed using so-called full-page printing. Full-page printing is printing in which a defined printing area of ​​the printed surface of the printed material 100 is completely filled with ink without any gaps. For example... Figure 5 As shown, the ink portion 111 can also be formed by printing with granular dots, such as halftone dots. The ink portion 111 can also be formed by ink that suppresses light transmission. The ink portion 111 can also be formed by ink that has light-blocking properties. The ink portion 111 is printed directly or indirectly on the substrate 120.

[0056] The printing layer 110 forms patterns through the ink portions 111. The printing layer 110 uses the halftone dots of the ink portions 111 to represent patterns. Furthermore, halftone dots refer to the grid-like dots used to represent the varying shades of a printed object. For example, the printing layer 110 can form a wood grain pattern through the ink portions 111. The printing layer 110 can also use the ink portions 111 to create various designs such as text, graphics, colors, and patterns.

[0057] The plurality of apertures 112 are holes that penetrate the printed layer 110. Even if the printed layer 110 comprises multiple layers, the plurality of apertures 112 are holes that penetrate multiple layers. The plurality of apertures 112 are each composed of micro-pores that are difficult to be visually identified with the naked eye. The plurality of apertures 112 are, for example, apertures with a diameter D of 2 micrometers or more and 10 micrometers or less. Alternatively, the plurality of apertures 112 are, for example, apertures with a diameter D of 5 micrometers or more and 100 micrometers or less. Preferably, the apertures 112 are mostly formed in the deeper printed portions of the printed layer 110, while the shallower printed portions are formed in the deeper printed portions.

[0058] Multiple holes 112 can be like Figure 3 The structure shown is dotted, or it can be as follows: Figure 4 The gap shown is formed by the ink section 111. Furthermore, Figure 3 and Figure 4 The arrangement of ink portion 111 and hole portion 112 shown is an example and is not limited to the arrangement shown.

[0059] Substrate 120 is a component on which a printed layer 110 is printed. Substrate 120 is printed directly or indirectly by ink portions 111. For example... Figure 4As shown, the substrate 120 of Embodiment 1 is a transparent component that allows light to pass through, and is a transparent substrate on which a printed layer 110 is printed. The substrate 120 of Embodiment 1 is, for example, a synthetic resin or glass, but is not limited to this material.

[0060] The substrate 120 can be a plate-shaped component or a thin film-shaped component. In addition, the substrate 120 can be not only a planar component, but also a three-dimensional curved component. Figure 4 and Figure 6 The white arrows shown indicate the transmission of light. (As...) Figure 4 and Figure 6 As shown, light passes through multiple apertures 112 and then through the printed layer 110.

[0061] like Figure 4 and Figure 6 As shown, light from the surface side of the printed material 100 can pass through the plurality of holes 112, penetrate the substrate 120, and illuminate the back side of the printed material 100. Additionally, as... Figure 4 and Figure 6 As shown, light from the back side of the printed material 100 toward the printed material 100 can pass through the substrate 120 and shine onto the surface side of the printed material 100 through a plurality of holes 112.

[0062] Light passes through the multiple apertures 112 through the printed layer 110, through the substrate 120, and through the printed material 100. That is, the printed material 100 can allow light to pass through portions of the multiple apertures 112 of the printed layer 110.

[0063] Furthermore, the layers constituting the printed matter 100 are not limited to the two layers of printing layer 110 and substrate 120. For example, the printed matter 100 may also have a protective layer made of transparent material above the printing layer 110 to protect the printing layer 110.

[0064] Figure 7 This is a partial enlarged view of the comparative example printout 100L. In a typical printout, as shown in the comparative example printout 100L, the dots of the ink portions 111L are arranged neatly in both the vertical and horizontal directions. In contrast, in the printout 100 of Embodiment 1, the dots of the ink portions 111 are arranged irregularly. The printout 100 can prevent moiré patterns by arranging the dots of the ink portions 111 irregularly. Moiré patterns are striped patterns that appear when geometrically regular patterns of dots or lines are superimposed.

[0065] [The effects of printed materials]

[0066] The printed material 100 includes: a printed layer 110 having ink portions 111 formed of printed ink and having a plurality of apertures 112 for light to pass through; and a substrate 120 on which the printed layer 110 is printed. The plurality of apertures 112 are each composed of tiny pores that are difficult to see with the naked eye. Even when the printed material 100 is used to form a decorative layer from the ink portions 111 of the printed layer 110 for design or various functions, light can still pass through the printed layer 110 through the plurality of apertures 112. Furthermore, when the substrate 120 is composed of a transparent component that allows light to pass through, light passes through the plurality of apertures 112 of the printed layer 110 and the substrate 120, from the surface side of the printed material 100 toward the back side or from the back side of the printed material 100 toward the surface side.

[0067] Furthermore, in the printed material 100, each of the multiple apertures 112 is composed of tiny pores that are difficult to see with the naked eye. Therefore, the presence of the multiple apertures 112 is not visible in the printed material 100 when light does not pass through the printed layer 110, making the presence of the ink portions 111 of the printed layer 110 obvious. When the ink portions 111 of the printed layer 110 form a decorative layer for imparting design or various functions, the presence of the multiple apertures 112 is not visible in the printed material 100 when light does not pass through the printed layer 110. Therefore, the decorative layer formed by the ink portions 111 is obvious in the printed material 100 when light does not pass through the printed layer 110.

[0068] Each of the multiple apertures 112 has a diameter D of 2 micrometers or more and 10 micrometers or less. Alternatively, each of the multiple apertures 112 has a diameter D of 5 micrometers or more and 100 micrometers or less. The multiple apertures 112 are difficult to visually identify with the naked eye due to their small opening diameters. Furthermore, when the multiple apertures 112 have a diameter D of 2 micrometers or more and 10 micrometers or less, they are even more difficult to visually identify with the naked eye compared to when the diameter D is 5 micrometers or more and 100 micrometers or less. With this structure, even when the printed material 100 is used to form a decorative layer from the ink portions 111 of the printing layer 110 for design purposes or various functions, light can still pass through the printing layer 110 via the multiple apertures 112.

[0069] The ink section 111 may also be made of light-blocking ink that is opaque to light. When the ink section 111 is made of light-blocking ink that is opaque to light, the printed matter 100 can block light in the ink section 111 and allow light to pass through in the aperture section 112. Therefore, it is possible to clearly distinguish between the part that is to allow light to pass through and the part that is to allow light to pass through.

[0070] Implementation Method 2

[0071] Figure 8This is a top view showing an example of the printed material 100 of Embodiment 2. Figure 9 This is a conceptual diagram showing an example of an enlarged cross-section of the display section 210 of the printed material 100 according to Embodiment 2. Components having the same functions and effects as those in the printed material 100 of Embodiment 1 are labeled with the same reference numerals, and their descriptions are omitted. Furthermore, Figure 9 The white arrow shown indicates the light passing through the aperture 112. Hereinafter, using... Figures 8-9 The structure of Embodiment 2 will be described focusing on the differences from Embodiment 1. Furthermore, any structures not described in Embodiment 2 are the same as those in Embodiment 1.

[0072] The printed material 100 of Embodiment 2 has a display section 210. The display section 210 will be described below. Figure 9 As shown, when the side that the user observes is designated as the surface side and the back side of the surface side is designated as the back side relative to the printed layer 110, as... Figure 8 As shown, the printed layer 110 has a display portion 210 on its surface side, which constitutes a portion for displaying text, graphics, symbols, or images. The display portion 210 is composed of a plurality of holes 112, and displays text, graphics, symbols, or images by transmitting light through the plurality of holes 112 from the back side.

[0073] Display unit 210 is, for example, a part that displays information. Figure 8 As shown, the display unit 210 may include, for example, a first display unit 211 for displaying text, a second display unit 212 for displaying graphics, and a third display unit 213 for displaying symbols or images. The text includes numbers, and the graphics include, for example, patterns or designs. There may be one or more display units 210.

[0074] exist Figure 8 The diagram illustrates an example of text, graphics, symbols, or images through the first display unit 211, the second display unit 212, and the third display unit 213. However, the displayed content is not limited to the example shown. For instance, the first display unit 211 may consist of multiple characters, or it may consist of Chinese characters or numbers. For example, the third display unit 213 may... Figure 8 The displayed symbols or images can be weather-related, or they can be vehicle-related information, etc.

[0075] In addition, Figure 8In the illustration, for the purpose of explaining the display unit 210, a first display unit 211, a second display unit 212, and a third display unit 213 are shown. However, the display unit 210 may also be composed of any one or more of the first display unit 211, the second display unit 212, and the third display unit 213. Furthermore, the display unit 210 may also consist of multiple instances of any one or more of the first display unit 211, the second display unit 212, and the third display unit 213.

[0076] Figure 10 It is the printed matter 100 of embodiment 2. Figure 8 The enlarged concept diagram of part E is shown. Figure 11 It is the printed matter 100 of embodiment 2. Figure 8 An enlarged conceptual diagram of another example of section E is shown. (See diagram below.) Figure 10 As shown, the number of holes 112 forming parts constituting the display section 210 is greater than the number of holes not constituting the display section 210. Figure 10 In the process, multiple holes 112 are also formed in the portions that do not constitute the display portion 210, but the portions that do not constitute the display portion 210 may also be formed by ink portions 111 through so-called full-page printing without holes 112. The multiple holes 112 can be formed as follows: Figure 10 The irregular arrangement shown can also be as follows: Figure 11 The arrangement is as shown in the diagram, with regular vertical and horizontal lines.

[0077] like Figure 1 and Figure 8 As shown, the printing layer 110 is composed of ink portions 111 forming a pattern. The pattern is, for example, as shown... Figure 1 and Figure 8 The image shown is of a wood grain pattern, but it is not limited to a wood grain pattern. Furthermore, patterns include designs. The display unit 210 uses, for example... Figure 9 The light transmitted through the multiple apertures 112 from the back side is shown, as Figure 8 The display is shown in a manner where light shines through the pattern and appears to float on it. When light does not pass through the multiple apertures 112 from the back side, the display unit 210, as shown... Figure 1 The pattern is not displayed on the design to maintain its appearance.

[0078] like Figure 9 As shown, the substrate 120 of Embodiment 2 is a transparent component that allows light to pass through, and is a transparent substrate on which a printed layer 110 is printed. The substrate 120 of Embodiment 2 is, for example, a synthetic resin or glass, but is not limited to these materials. The substrate 120 can be a plate-shaped component or a film-shaped component such as a thin film. In addition, the substrate 120 can be not only a planar component, but also a three-dimensional curved component. Figure 9 The white arrows shown indicate the transmission of light. (As...) Figure 9 As shown, light passes through multiple apertures 112 and then through the printed layer 110.

[0079] like Figure 9 As shown, light from the back side of the printed material 100 can pass through the substrate 120, through multiple holes 112, and onto the surface side of the printed material 100. The light passes through the substrate 120, through the multiple holes 112, through the printing layer 110, and through the printed material 100. That is, the printed material 100 can allow light to pass through portions of the multiple holes 112 in the printing layer 110.

[0080] Figure 12 This is a conceptual diagram illustrating an example of a display device 500 using the printed material 100 of Embodiment 2. The display device 500 includes the printed material 100 and a light-emitting device 400 disposed on the back side of the printed material 100. In the display device 500, the printed material 100 constitutes a display panel, and text, graphics, symbols, or images are displayed on the display section 210 by light emitted from the light-emitting device 400 and transmitted through a plurality of apertures 112 from the back side.

[0081] The light-emitting device 400 constitutes the light-emitting part in the display device 500. The light-emitting device 400 is in a light-emitting state by being set to an "on" state and in a non-light-emitting state by being set to an "off" state. When light is emitted from the light-emitting device 400, light passes through the plurality of holes 112 of the printed material 100 and light passes through the printed layer 110. When light is not emitted from the light-emitting device 400, light does not pass through the plurality of holes 112 of the printed material 100 and light does not pass through the printed layer 110.

[0082] When the light-emitting device 400 emits light, the display unit 210 appears on the surface of the printed material 100 due to the light passing through the plurality of holes 112. When the light-emitting device 400 does not emit light, light does not pass through the plurality of holes 112, and the display unit 210 does not appear on the surface of the printed material 100.

[0083] The light-emitting device 400 includes, for example, a light source substrate 410 and a light-emitting element 420 that serves as a light source. As an example, the light source substrate 410 is a substrate formed in a plate shape and on which the light-emitting element 420 is mounted. The light source substrate 410 is provided with a light source circuit including the light-emitting element 420.

[0084] The light-emitting element 420 is, for example, an LED (Light Emitting Diode). The light-emitting device 400 is, for example, a COB (Chip-On Board) – LED (Light Emitting Diode). Furthermore, Figure 12 The light-emitting device 400 shown is conceptual, and the number and arrangement of the light-emitting elements 420 are not limited to those shown.

[0085] Furthermore, the light-emitting element 420 can also be a solid-state light-emitting element other than an LED, such as an organic EL (Electro-Luminescence) or a laser. In addition, the light-emitting device 400 can be any light-emitting device, such as a device using a light bulb, and is not limited to a device that has LEDs installed.

[0086] The light-emitting device 400 or the light-emitting element 420 may also be respectively provided in the first display unit 211, the second display unit 212 and the third display unit 213 (see reference). Figure 8 When multiple display units 210 are provided, the light-emitting device 400 or the light-emitting element 420 may also be provided for each display unit 210.

[0087] Display device 500 via, for example Figure 9 The light transmitted through the multiple apertures 112 from the back side is shown, as Figure 8 The display unit 210 is shown in a manner where light passes through the pattern, causing the display section 210 to appear above the pattern. The display unit 210 is displayed when light does not pass through the multiple apertures 112 from the back side, as... Figure 1 The display unit 210 shown does not display the pattern on the printed layer 110, but maintains the appearance of the pattern.

[0088] [The effects of printed materials]

[0089] The printing layer 110 of the printed material 100 in Embodiment 2 is as follows Figure 8 The diagram shows a display section 210 on its surface side, comprising portions for displaying text, graphics, symbols, or images. The display section 210 is composed of a plurality of apertures 112, and displays text, graphics, symbols, or images by light passing through the apertures 112 from the back side. The substrate 120 is a transparent component that allows light to pass through, and is a transparent substrate on which a printing layer 110 is printed. The presence of the display section 210 is not discernible on the printed material 100 when light does not pass through the printing layer 110. Therefore, the design of the decorative layer formed by the ink portions 111 is clearly visible on the printed material 100 when light does not pass through the printing layer 110. The presence of the display section 210 is discernible on the printed material 100 when light passes through the printing layer 110 via the apertures 112. Therefore, the printed material 100 can display the display content of the display section 210 when light passes through the printing layer 110, for example, it can convey information formed by the display content of the display section 210.

[0090] Furthermore, the number of holes 112 forming parts constituting the display section 210 is greater than the number of holes not constituting the display section 210. With this structure, the printed material 100 can make the brightness difference between the display section 210 and other parts obvious, and can make the display of the display section 210 clear.

[0091] Furthermore, the display unit 210 displays light by passing through the multiple apertures 112 from the back side, so that the light passes through the pattern of the printed layer 110 and appears on the pattern of the printed layer 110. When light does not pass through the multiple apertures 112 from the back side, the display unit 210 does not appear on the pattern of the printed layer 110, thus maintaining the appearance of the pattern of the printed layer 110. With this structure, the printed material 100 can recognize the presence of the display unit 210 when light passes through the multiple apertures 112 on the printed layer 110. With this structure, the design of the decorative layer formed by the ink portions 111 can be clearly seen on the printed material 100 when light does not pass through the printed layer 110.

[0092] With this structure, the display of the display unit 210 can be made to appear on the pattern formed by the printing layer 110 by light passing through the printed material 100, allowing the viewer of the printed material 100 to recognize the presence of the display unit 210. Furthermore, with this structure, the display unit 210 is not displayed on the printing layer 110 when light does not pass through it, so the viewer of the printed material 100 will not be aware of its presence. In other words, by controlling the presence or absence of light passing through the multiple apertures 112, the viewer of the printed material 100 can switch between recognizing and not recognizing the presence of the display unit 210.

[0093] Furthermore, the display device 500 includes a printed material 100 and a light-emitting device 400 disposed on the back side of the printed material 100. In the display device 500, the printed material 100 constitutes a display panel, and text, graphics, symbols, or images are displayed on the display section 210 by light emitted from the light-emitting device 400 and transmitted through multiple apertures 112 from the back side. With this structure, the display device 500 can identify the presence of the display section 210 of the printed material 100 even when light emitted from the light-emitting device 400 passes through the multiple apertures 112 and through the printed layer 110. With this structure, the display device 500 can make the design of the decorative layer formed by the ink portions 111 of the printed material 100 clearly visible even when no light is emitted from the light-emitting device 400 and no light passes through the printed layer 110 of the printed material 100.

[0094] With this structure, the display device 500 allows light emitted from the light-emitting device 400 to pass through the printing layer 110, enabling the display of the display section 210 to appear on the pattern formed by the printing layer 110 of the printed matter 100. Therefore, the display device 500 allows the observer of the printed matter 100 to recognize the presence of the display section 210 through the light emitted by the light-emitting device 400. Furthermore, with this structure, the display device 500 can prevent the printing layer 110 from being displayed on the display section 210 when no light is emitted from the light-emitting device 400 and light does not pass through the printing layer 110, thus preventing the observer of the printed matter 100 from becoming aware of the presence of the display section 210. The display device 500 can make the design of the decorative layer formed by the ink portion 111 of the printed matter 100 clearly visible without the observer of the printed matter 100 becoming aware of the presence of the display section 210.

[0095] The display device 500, by turning on the light-emitting device 400 and allowing light to pass through the printed material 100, enables a person viewing the printed material 100 to recognize the presence of the display unit 210. Conversely, by turning off the light-emitting device 400 and not allowing light to pass through the printed material 100, the display device 500 enables a person viewing the printed material 100 to not recognize the presence of the display unit 210. In other words, the display device 500 can switch the presence or absence of the display unit 210 by switching the light-emitting device 400 on or off.

[0096] The ink portion 111 can also be made of light-blocking ink. When the ink portion 111 is made of light-blocking ink, the boundary between the ink portion 111 and the plurality of perforations 112 becomes more distinct in the printed matter 100. The arrangement of the plurality of perforations 112 provides the following advantages when displaying text, graphics, symbols, or images on the display section 210: When the ink portion 111 is made of light-blocking ink, compared to when it is made of ink with low light-blocking properties, the outlines and boundaries of text, etc., can be clearly distinguished in the printed matter 100, thus improving visual recognizability.

[0097] Implementation Method 3

[0098] Figure 13 This is a conceptual diagram showing an example of an enlarged cross-section of the printed material 100 according to Embodiment 3. Components having the same function and effect as those in the printed materials 100 of Embodiments 1 and 2 are labeled with the same reference numerals, and their descriptions are omitted. Furthermore, Figure 13 The white arrow shown indicates the light passing through the aperture 112. Hereinafter, using... Figure 13 The structure of Embodiment 3 will be described focusing on its differences from Embodiments 1 and 2. Furthermore, any structures not described in Embodiment 3 are the same as those in Embodiments 1 and 2.

[0099] The printed material 100 of Embodiment 3 has a display printing layer 310, which has a plurality of light-shielding ink portions 311 made of light-shielding ink that is light-blocking. The printed material 100 can block the transmission of light by means of the light-shielding ink portions 311. The light-shielding ink portions 311 and the display printing layer 310 are formed by printing. In the printed material 100, the printing layer 110 and the display printing layer 310 are arranged in a stacked state, with the printing layer 110 disposed on the surface side and the display printing layer 310 disposed on the back side opposite to the printing layer 110. As an example, the display printing layer 310 is disposed on the opposite side of the printing layer 110 through the substrate 120.

[0100] In the printed material 100, in the lamination direction T of the printed layer 110 and the display printed layer 310, a plurality of light-shielding ink portions 311 are disposed facing the ink portions 111 of the printed layer 110. In the printed material 100, in the lamination direction T of the printed layer 110 and the display printed layer 310, the light-shielding ink portions 311 are disposed in portions that do not face the aperture portions 112 constituting the display portion 210. In other words, in the printed material 100, in the lamination direction T of the printed layer 110 and the display printed layer 310, the light-shielding ink portions 311 are disposed in portions that do not face the aperture portions 112 constituting the display portion 210.

[0101] The light-blocking ink portion 311 may also face the aperture portion 112 that does not constitute the display portion 210. The space between adjacent light-blocking ink portions 311 is configured to face one or more aperture portions 112. The printed matter 100 can block the transmission of light through the light-blocking ink portion 311, and by blocking the transmission of light in portions other than the display portion 210, the display of graphics, etc., on the light-transmitting display portion 210 can be made clear.

[0102] Figure 14 This is a conceptual diagram showing the relationship between the light-blocking ink portion 311 and the display portion 210 as viewed in the lamination direction T of the printed material 100 in Embodiment 3. Furthermore, Figure 14 For example is Figure 8 Part E. Figure 14 In the image, the left side represents the display printing layer 310, and the right side represents the printing layer 110. Multiple light-shielding ink portions 311 are arranged, for example, along the outer edge 215 of the display portion 210 in the stacking direction T between the printing layer 110 and the display printing layer 310.

[0103] Figure 15 This is a conceptual diagram showing another example of an enlarged cross-section of the printed material 100 according to Embodiment 3. The stacking order of the printed layer 110, the substrate 120, and the display printed layer 310 is not limited to... Figure 13 In this way. For example... Figure 15As shown, the display printing layer 310 can also be disposed between the printing layer 110 and the substrate 120. The printing layer 110 is printed on the substrate 120 via the display printing layer 310. The printed material 100 only needs to be formed such that the pattern formed on the printing layer 110 can be seen by the user. In addition, the layers constituting the printed material 100 are not limited to the three layers of the printing layer 110, the substrate 120, and the display printing layer 310. For example, the printed material 100 may also have a protective layer made of a transparent material above the printing layer 110 to protect the printing layer 110.

[0104] Figure 16 This is a conceptual diagram illustrating an example of a display device 500 using the printed material 100 of Embodiment 3. The display device 500 includes the printed material 100 and a light-emitting device 400 disposed on the back side of the printed material 100. In the display device 500, the printed material 100 constitutes a display panel, and text, graphics, symbols, or images are displayed on the display section 210 by light emitted from the light-emitting device 400 and transmitted through a plurality of apertures 112 from the back side.

[0105] like Figure 13 , Figure 15 and Figure 16 As shown, the substrate 120 of Embodiment 3 is a transparent component that allows light to pass through, and it is a transparent substrate on which a printed layer 110 is printed. The substrate 120 of Embodiment 3 is, for example, a synthetic resin or glass, but is not limited to this material. The substrate 120 can be a plate-shaped component or a film-shaped component such as a thin film. In addition, the substrate 120 can be not only a planar component, but also a three-dimensional curved component. Figure 13 , Figure 15 and Figure 16 The white arrows shown indicate the transmission of light. (As...) Figure 13 , Figure 15 and Figure 16 As shown, light passes through multiple apertures 112 and then through the printed layer 110.

[0106] like Figure 13 , Figure 15 and Figure 16 As shown, light from the back side of the printed material 100 can pass through the substrate 120, through multiple holes 112, and onto the surface side of the printed material 100. The light passes through the substrate 120, through the multiple holes 112, through the printing layer 110, and through the printed material 100. That is, the printed material 100 can allow light to pass through portions of the multiple holes 112 in the printing layer 110.

[0107] [The effects of printed materials]

[0108] The printed material 100 of Embodiment 3 has a display printing layer 310, which has a plurality of light-shielding ink portions 311 made of light-shielding ink with light-blocking properties. In the printed material 100, the printing layer 110 and the display printing layer 310 are arranged in a stacked state, with the printing layer 110 disposed on the surface side and the display printing layer 310 disposed on the back side opposite to the printing layer 110. In the printed material 100, in the stacking direction T of the printing layer 110 and the display printing layer 310, the plurality of light-shielding ink portions 311 are arranged facing the ink portions 111 of the printing layer 110.

[0109] The printed material 100, through the light-blocking properties of the light-blocking ink portion 311, makes the brightness difference between the display portion 210 and other areas clearly apparent, thus ensuring clear display of the display portion 210. With this structure, the boundary between the ink portion 111 and the plurality of perforations 112 becomes more distinct in the printed material 100. When the light-blocking ink portion 311 is composed of light-blocking ink, compared to when it is composed of ink with low light-blocking properties, the outlines and boundaries of text and other elements can be clearly distinguished, thereby improving visual recognizability.

[0110] In Embodiment 3, the plurality of light-shielding ink portions 311 of the printed material 100 are arranged along the outer edge 215 of the display portion 210 in the lamination direction T between the printed layer 110 and the display printed layer 310. With this structure, the boundary between the ink portions 111 and the plurality of perforations 112 becomes more distinct in the printed material 100. This structure also allows the printed material 100 to clearly distinguish the outlines and boundaries of text, thereby improving the visual recognizability of the display portion 210.

[0111] The display printing layer 310 is disposed on the opposite side of the printing layer 110, separated from the substrate 120. Alternatively, the display printing layer 310 may be disposed between the printing layer 110 and the substrate 120. The arrangement of the display printing layer 310, the printing layer 110, and the substrate 120 can be selected according to the usage or the structure of the printing apparatus, etc.

[0112] Furthermore, the display device 500 includes a printed material 100 and a light-emitting device 400 disposed on the back side of the printed material 100. In the display device 500, the printed material 100 constitutes a display panel, and text, graphics, symbols, or images are displayed on the display section 210 by light emitted from the light-emitting device 400 and transmitted through multiple apertures 112 from the back side. The display device 500 can switch the presence or absence of display on the display section 210 by switching the light-emitting device 400 on or off. With this structure, the display device 500 can achieve the same effect as the display device 500 of Embodiment 1.

[0113] Implementation Method 4

[0114] Figure 17This is a conceptual diagram showing an example of an enlarged cross-section of the printed material 100 according to Embodiment 4. For constituent elements having the same function and effect as the printed materials 100 of Embodiments 1 to 3, the same reference numerals are used, and their descriptions are omitted. Furthermore, Figure 17 The white arrow shown indicates the light passing through the aperture 112. Hereinafter, using... Figure 17 The structure of Embodiment 4 will be described focusing on the differences from Embodiments 1 to 3. Furthermore, structures not described in Embodiment 4 are the same as those in Embodiments 1 to 3.

[0115] The printed material 100 of Embodiment 4 has a display printing layer 310, which has a plurality of translucent ink portions 312 made of translucent ink that transmits light. The translucent ink portions 312 and the display printing layer 310 are formed by printing. In the printed material 100, the plurality of translucent ink portions 312 are made of at least one color of colored ink. The translucent ink portions 312 can be of one color, or different colors can be used depending on the position of the ink. For example, the color of the ink in the translucent ink portions 312 can also be based on the first display portion 211, the second display portion 212, and the third display portion 213 (see reference). Figure 8 Different colors are used.

[0116] In the printed material 100, the printed layer 110 and the display printed layer 310 are configured in a stacked state, with the printed layer 110 disposed on the surface side and the display printed layer 310 disposed on the back side relative to the printed layer 110. As an example, the display printed layer 310 is disposed on the opposite side of the printed layer 110, separated from the substrate 120.

[0117] In the lamination direction T of the printed layer 110 and the display printed layer 310, the light-transmitting ink portion 312 is provided in a position facing the display portion 210. In the printed matter 100, in the lamination direction T of the printed layer 110 and the display printed layer 310, the light-transmitting ink portion 312 is provided in a position facing the aperture portion 112 constituting the display portion 210. Furthermore, the light-transmitting ink portion 312 may also have a portion facing the ink portion 111 in the lamination direction T of the printed layer 110 and the display printed layer 310. That is, in the lamination direction T, the light-transmitting ink portion 312 may also be configured to face one or more aperture portions 112.

[0118] Figure 18 This is a conceptual diagram showing another example of an enlarged cross-section of the printed material 100 according to Embodiment 4. Furthermore, in Figure 18 In order to make the distinction between adjacent translucent ink areas 312 more obvious, the type of shadow is changed. The stacking order of the printing layer 110, the substrate 120, and the display printing layer 310 is not limited to... Figure 17 In this way. For example... Figure 18As shown, the display printing layer 310 can also be disposed between the printing layer 110 and the substrate 120. The printing layer 110 is printed on the substrate 120 via the display printing layer 310. The printed material 100 only needs to be formed such that the pattern formed on the printing layer 110 can be seen by the user. In addition, the layers constituting the printed material 100 are not limited to the three layers of the printing layer 110, the substrate 120, and the display printing layer 310. For example, the printed material 100 may also have a protective layer made of transparent material above the printing layer 110 to protect the printing layer 110. Furthermore, other ink components or filler materials may be used between adjacent light-transmitting ink portions 312.

[0119] Figure 19 This is a conceptual diagram showing another example of an enlarged cross-section of the printed material 100 according to Embodiment 4. (See diagram below.) Figure 19 As shown, the printed material 100 may also have a translucent ink portion 312 disposed in the aperture portion 112. For example... Figure 19 As shown, the printed material 100 may also be configured as at least a portion of the printed layer 110 and form the same layer as the display printed layer 310.

[0120] Figure 20 This is a conceptual diagram showing another example of an enlarged cross-section of the printed material 100 according to Embodiment 4. The plurality of translucent ink portions 312 may, for example, include multiple colored inks of different concentrations. Figure 20 As shown, the plurality of translucent ink portions 312 may include, for example, a translucent ink portion 312A composed of a relatively concentrated colored ink and a translucent ink portion 312B composed of a relatively light-concentrated colored ink.

[0121] Figure 21 This is a conceptual diagram illustrating an example of a display device 500 using the printed material 100 of Embodiment 4. The display device 500 includes the printed material 100 and a light-emitting device 400 disposed on the back side of the printed material 100. In the display device 500, the printed material 100 constitutes a display panel, and text, graphics, symbols, or images are displayed on the display section 210 by light emitted from the light-emitting device 400 and transmitted through a plurality of apertures 112 from the back side.

[0122] like Figures 17-20 As shown, the substrate 120 of Embodiment 4 is a transparent component that allows light to pass through, and it is a transparent substrate on which a printed layer 110 is printed. The substrate 120 of Embodiment 4 is, for example, a synthetic resin or glass, but is not limited to these materials. The substrate 120 can be a plate-shaped component or a film-shaped component such as a thin film. In addition, the substrate 120 can be not only a planar component, but also a three-dimensional curved component. Figures 17-20 The white arrows shown indicate the transmission of light. (As...) Figures 17-20 As shown, light passes through multiple apertures 112 and then through the printed layer 110.

[0123] like Figures 17-20 As shown, light from the back side of the printed material 100 can pass through the substrate 120, through multiple holes 112, and onto the surface side of the printed material 100. The light passes through the substrate 120, through the multiple holes 112, through the printing layer 110, and through the printed material 100. That is, the printed material 100 can allow light to pass through portions of the multiple holes 112 in the printing layer 110.

[0124] [The effects of printed materials]

[0125] The printed material 100 of Embodiment 4 has a display printing layer 310, which has a plurality of light-transmitting ink portions 312 made of light-transmitting ink. In the printed material 100, the plurality of light-transmitting ink portions 312 are made of at least one color ink. In the printed material 100, the printing layer 110 and the display printing layer 310 are arranged in a stacked state, with the printing layer 110 disposed on the surface side and the display printing layer 310 disposed on the back side opposite to the printing layer 110. As an example, the display printing layer 310 is disposed on the opposite side of the printing layer 110 through the substrate 120. In the stacking direction T of the printing layer 110 and the display printing layer 310, the light-transmitting ink portions 312 are provided in the portion facing the display portion 210.

[0126] With this structure, the printed material 100 can color the display of the display unit 210 by transmitting the color of the ink through the translucent ink portion 312. Because this structure enables coloring of the display of the display unit 210 on the printed material 100, the color-separated display unit 210 can differentiate information content based on color separation. For example, the printed material 100 can differentiate the importance of displayed information by assigning high importance to the red display unit 210, medium importance to the yellow display unit 210, and low importance to the blue display unit 210, etc.

[0127] With this structure, the display portion 210 of the printed material 100 can be colored, thus making the presence of the display portion 210 more apparent when it is displayed. For example, with the above structure, the printed material 100 can make the color of the pattern formed by the printing layer 110 and the color of the display portion 210 complementary colors. With the above structure, the printed material 100 can make the color difference between the display portion 210 and other parts of the display portion 210 more obvious, thus making the display of the display portion 210 clear.

[0128] The display printing layer 310 is disposed on the opposite side of the printing layer 110, separated from the substrate 120. Alternatively, the display printing layer 310 may be disposed between the printing layer 110 and the substrate 120. The arrangement of the display printing layer 310, the printing layer 110, and the substrate 120 can be selected according to the usage or the structure of the printing apparatus, etc.

[0129] Furthermore, the display device 500 includes a printed material 100 and a light-emitting device 400 disposed on the back side of the printed material 100. In the display device 500, the printed material 100 constitutes a display panel, and text, graphics, symbols, or images are displayed on the display section 210 by light emitted from the light-emitting device 400 and transmitted through multiple apertures 112 from the back side. The display device 500 can switch the presence or absence of display on the display section 210 by switching the light-emitting device 400 on or off. With this structure, the display device 500 can achieve the same effect as the display device 500 of Embodiment 1.

[0130] Implementation Method 5

[0131] Figure 22 This is a conceptual diagram showing an example of an enlarged cross-section of the printed material 100 according to Embodiment 5. For constituent elements having the same function and effect as the printed materials 100 of Embodiments 1 to 4, the same reference numerals are used, and their descriptions are omitted. Furthermore, Figure 22 The white arrow shown indicates the light passing through the aperture 112. Hereinafter, using... Figure 22 The structure of Embodiment 5 will be described focusing on the differences from Embodiments 1 to 4. Furthermore, any structures not described in Embodiment 5 are the same as those in Embodiments 1 to 4.

[0132] The printed material 100 of Embodiment 5 has a display printing layer 310, which has a plurality of light-transmitting ink portions 312 made of light-transmitting ink and light-shielding ink portions 311 made of light-blocking ink. The plurality of light-transmitting ink portions 312 are made of at least one color ink.

[0133] In the printed material 100, the printed layer 110 and the display printed layer 310 are configured in a stacked state, with the printed layer 110 disposed on the surface side and the display printed layer 310 disposed on the back side relative to the printed layer 110. As an example, the display printed layer 310 is disposed on the opposite side of the printed layer 110, separated from the substrate 120.

[0134] In the printed material 100, in the lamination direction T of the printed layer 110 and the display printed layer 310, the light-shielding ink portion 311 is disposed facing the ink portion 111 of the printed layer 110. In the printed material 100, in the lamination direction T of the printed layer 110 and the display printed layer 310, the light-shielding ink portion 311 is disposed in a portion that does not face the aperture portion 112 constituting the display portion 210. In other words, in the printed material 100, in the lamination direction T of the printed layer 110 and the display printed layer 310, the light-shielding ink portion 311 is disposed in a portion that does not face the display portion 210. Furthermore, the light-shielding ink portion 311 may also face an aperture portion 112 that does not constitute the display portion 210. The space between adjacent light-shielding ink portions 311 may also be configured to face one or more aperture portions 112.

[0135] In the printed material 100, in the lamination direction T of the printed layer 110 and the display printed layer 310, a light-transmitting ink portion 312 is provided in a position facing the display portion 210. In the printed material 100, in the lamination direction T of the printed layer 110 and the display printed layer 310, the light-transmitting ink portion 312 is provided in a position facing the aperture portion 112 constituting the display portion 210. Furthermore, the light-transmitting ink portion 312 may also have a portion facing the ink portion 111 in the lamination direction T of the printed layer 110 and the display printed layer 310. That is, one light-blocking ink portion 311 may also be configured to face one or more aperture portions 112.

[0136] The light-blocking ink portion 311 may also be disposed along the outer edge 215 of the display portion 210 in the lamination direction T between the printing layer 110 and the display printing layer 310 (see reference). Figure 14 ).

[0137] Figure 23 This is a conceptual diagram showing another example of an enlarged cross-section of the printed material 100 according to Embodiment 5. The stacking order of the printed layer 110, the substrate 120, and the display printed layer 310 is not limited to... Figure 22 In this way. For example... Figure 23 As shown, the display printing layer 310 can also be disposed between the printing layer 110 and the substrate 120. The printing layer 110 is printed on the substrate 120 via the display printing layer 310. The printed material 100 only needs to be formed such that the pattern formed on the printing layer 110 can be seen by the user. In addition, the layers constituting the printed material 100 are not limited to the three layers of the printing layer 110, the substrate 120, and the display printing layer 310. For example, the printed material 100 may also have a protective layer made of a transparent material above the printing layer 110 to protect the printing layer 110.

[0138] Figure 24This is a conceptual diagram illustrating an example of a display device 500 using the printed material 100 of Embodiment 5. The display device 500 includes the printed material 100 and a light-emitting device 400 disposed on the back side of the printed material 100. In the display device 500, the printed material 100 constitutes a display panel, and text, graphics, symbols, or images are displayed on the display section 210 by light emitted from the light-emitting device 400 and transmitted through a plurality of apertures 112 from the back side.

[0139] like Figures 22-24 As shown, the substrate 120 of Embodiment 5 is a transparent component that allows light to pass through, and it is a transparent substrate on which a printed layer 110 is printed. The substrate 120 of Embodiment 5 is, for example, a synthetic resin or glass, but is not limited to this material. The substrate 120 can be a plate-shaped component or a film-shaped component such as a thin film. In addition, the substrate 120 can be not only a planar component, but also a three-dimensional curved component. Figures 22-24 The white arrows shown indicate the transmission of light. (As...) Figures 22-24 As shown, light passes through multiple apertures 112 and then through the printed layer 110.

[0140] like Figures 22-24 As shown, light from the back side of the printed material 100 can pass through the substrate 120, through multiple holes 112, and onto the surface side of the printed material 100. The light passes through the substrate 120, through the multiple holes 112, through the printing layer 110, and through the printed material 100. That is, the printed material 100 can allow light to pass through portions of the multiple holes 112 in the printing layer 110.

[0141] [The effects of printed materials]

[0142] The printed material 100 of Embodiment 5 has a display printing layer 310, which has a plurality of light-transmitting ink portions 312 made of light-transmitting ink and a light-shielding ink portion 311 made of light-blocking ink. The plurality of light-transmitting ink portions 312 are made of at least one color ink. In the printed material 100, in the lamination direction T between the printing layer 110 and the display printing layer 310, the light-shielding ink portion 311 is disposed facing the ink portion 111 of the printing layer 110. In the printed material 100, in the lamination direction T between the printing layer 110 and the display printing layer 310, the light-transmitting ink portion 312 is disposed in the portion facing the display portion 210.

[0143] With this structure, the printed material 100 can make the brightness difference between the display section 210 and other parts of the display section 210 more obvious, thus making the display section 210 clearer. With this structure, the boundary between the ink section 111 and the plurality of perforations 112 in the printed material 100 becomes more distinct. When the light-blocking ink section 311 of the printed material 100 is composed of light-blocking ink, compared to when it is composed of ink with low light-blocking properties, the outlines and boundaries of characters can be clearly distinguished, thereby improving visual recognizability.

[0144] With this structure, the boundary between the ink portion 111 and the plurality of perforations 112 becomes clear in the printed material 100, and the color of the ink transmitted through the translucent ink portion 312 enables the display portion 210 to be colored. Because the printed material 100 enables the display portion 210 to be colored, the color-separated display portion 210 allows for the differentiation of information content based on color separation.

[0145] In Embodiment 5, the light-shielding ink portion 311 of the printed material 100 is disposed along the outer edge 215 of the display portion 210 in the lamination direction T between the printed layer 110 and the display printed layer 310. With this structure, the boundary between the ink portion 111 and the plurality of perforations 112 becomes more distinct in the printed material 100. This structure also allows the printed material 100 to clearly distinguish the outlines and boundaries of text, thereby improving the visual recognizability of the display portion 210.

[0146] The display printing layer 310 is disposed on the opposite side of the printing layer 110, separated from the substrate 120. Alternatively, the display printing layer 310 may be disposed between the printing layer 110 and the substrate 120. The arrangement of the display printing layer 310, the printing layer 110, and the substrate 120 can be selected according to the usage or the structure of the printing apparatus, etc.

[0147] Furthermore, the display device 500 includes a printed material 100 and a light-emitting device 400 disposed on the back side of the printed material 100. In the display device 500, the printed material 100 constitutes a display panel, and text, graphics, symbols, or images are displayed on the display section 210 by light emitted from the light-emitting device 400 and transmitted through multiple apertures 112 from the back side. The display device 500 can switch the presence or absence of display on the display section 210 by switching the light-emitting device 400 on or off. With this structure, the display device 500 can achieve the same effect as the display device 500 of Embodiment 1.

[0148] The printed material 100 of Embodiment 5 includes the structure of the printed material 100 of Embodiments 3 and 4, and therefore can achieve the same effect as the printed material 100 of Embodiments 3 and 4.

[0149] Implementation Method 6

[0150] Figure 25 This is an exploded concept diagram showing an example of the solar cell 600 of Embodiment 6. Figure 26 This is a conceptual diagram showing an example of an enlarged cross-section of the solar cell 600 according to Embodiment 6. For constituent elements having the same function and effect as the printed materials 100 of Embodiments 1 to 5, the same reference numerals are used, and their descriptions are omitted. Furthermore, Figure 26 The white arrow shown indicates the light passing through the aperture 112. Hereinafter, using... Figure 25 and Figure 26 The structure of Embodiment 6 will be described focusing on the differences from Embodiments 1 to 5. Furthermore, any structures not described in Embodiment 6 are the same as those in Embodiments 1 to 5.

[0151] The printed material 100 in Embodiment 6 is a solar cell 600. The solar cell 600 is a device that converts solar energy into electrical energy using the photoelectric effect of semiconductors. As an example, the solar cell 600 is a perovskite solar cell. However, the solar cell 600 is not limited to a perovskite solar cell. For example, the solar cell 600 can also be other types of solar cells, such as silicon-based solar cells.

[0152] The solar cell 600 includes: a printed layer 110 having an ink portion 111 composed of printed ink and having a plurality of aperture portions 112 through which light passes; and a substrate 120 on which the printed layer 110 is printed.

[0153] The printed layer 110 of the solar cell 600 is the same as the printed layer 110 of the printed material 100 in Embodiment 1. The printed layer 110 constitutes a part of the solar cell 600 and is used to decorate the solar cell 600. In Embodiment 6, the ink portion 111 in the printed layer 110 may also be a translucent ink.

[0154] Each of the multiple apertures 112 is composed of tiny pores that are difficult to see with the naked eye. Each of the multiple apertures 112 has, for example, a diameter D of 2 micrometers or more and 10 micrometers or less. Alternatively, each of the multiple apertures 112 has, for example, a diameter D of 5 micrometers or more and 100 micrometers or less. The printed layer 110 of Embodiment 6 is, for example, a layer with a light transmittance of 60% or more and 90% or less.

[0155] The substrate 120 is formed from a flexible, thin-film member. The substrate 120 is a member on which a printed layer 110 is printed. The substrate 120 includes a power-generating layer 120A, which is stacked with the printed layer 110 and generates electricity by transmitting light through a plurality of apertures 112 in the printed layer 110. The printed layer 110 is printed on the light-receiving side of the power-generating layer 120A. The printed layer 110 may be directly printed on the light-receiving surface of the power-generating layer 120A, for example. For example, the printed layer 110 may be directly printed on the perovskite surface constituting the power-generating layer 120A. Direct printing also includes coatings applied by printing. Furthermore, a coating may be applied to the top of the perovskite surface. The printed layer 110 may also be indirectly printed on the light-receiving surface of the power-generating layer 120A, for example, via a transparent film.

[0156] The power generation layer 120A is a layer that generates photoelectric conversion through light irradiation, producing electrons and pores from excitons generated by absorbing light. The solar cell 600 is, for example, a thin-film solar cell, and the power generation layer 120A is, for example, a flexible layer. The printed layer 110 and the power generation layer 120A, for example, constitute part of a perovskite solar cell.

[0157] The substrate 120 includes a thin film layer 120B on the side of the power generation layer 120A opposite to the printed layer 110. The thin film layer 120B is composed of a thin film-like component such as a thin film and is flexible. The thin film layer 120B is, for example, a synthetic resin, but is not limited to this material. Furthermore, the layers constituting the substrate 120 of the solar cell 600 are not limited to the power generation layer 120A and the thin film layer 120B. Although not shown in the figure, the substrate 120 of the solar cell 600, in addition to the power generation layer 120A, has various functional layers such as an electrode layer that perform the function of the solar cell 600.

[0158] Figure 26 The white arrows shown indicate the transmission of light. (As...) Figure 26 As shown, light passes through multiple apertures 112 and then through the printed layer 110. Figure 26 As shown, light from the surface of the solar cell 600 toward the power generation layer 120A passes through multiple holes 112 in the printed layer 110. That is, the light received by the solar cell 600 passes through the multiple holes 112 and through the printed layer 110 to reach the power generation layer 120A of the solar cell 600.

[0159] [The effects of printed materials]

[0160] The solar cell 600 is a printed material 100. The substrate 120 of the printed material 100 includes a power-generating layer 120A, which is stacked with a printed layer 110. Power generation occurs through light passing through a plurality of apertures 112 in the printed layer 110. The printed layer 110 is printed on the light-receiving side of the power-generating layer 120A. Even if the ink portions 111 of the printed layer 110 form a decorative layer for design or various functions, light can still pass through the printed layer 110 through the plurality of apertures 112, thus enabling power generation through the power-generating layer 120A of the substrate 120. Since the solar cell 600 includes the printed layer 110, power generation can occur in a state where the printed layer 110 is effectively utilized in design.

[0161] Furthermore, the printed layer 110 and the power-generating layer 120A constitute part of a perovskite solar cell. Perovskite solar cells can be mass-produced using printing technology. Therefore, the solar cell 600 can utilize printing technology to manufacture the printed layer 110 and the power-generating layer 120A, thus simplifying manufacturing and reducing costs compared to manufacturing solar cells without printing technology. Perovskite solar cells exhibit strong resistance to deformation and can be lightweight, allowing the solar cell 600 to be installed in locations where silicon solar cells have been unable to be installed until now, while still utilizing the design and functions of the printed layer 110.

[0162] Furthermore, the printed layer 110 has a light transmittance of 60% or more and 90% or less. Because the solar cell 600 has this structure in its printed layer 110, it can generate electricity through the power generation layer 120A of the substrate 120. Since the solar cell 600 includes the printed layer 110, it can generate electricity in a way that effectively utilizes the printed layer 110 in its design.

[0163] Furthermore, the substrate 120 is formed from a flexible, thin-film component. The power generation layer 120A is a flexible layer, and the solar cell 600 is a thin-film solar cell. Because of this structure, the solar cell 600 has strong resistance to deformation and can be lightweight. Therefore, it is possible to place the solar cell 600 in locations where silicon solar cells could not be installed until now, while still utilizing the design and other functions of the printed layer 110.

[0164] Implementation Method 7

[0165] Figure 27 This is an exploded concept diagram showing an example of the solar cell system 700 of Embodiment 7. Figure 28 This is a conceptual diagram showing an example of an enlarged cross-section of the solar cell system 700 according to Embodiment 7. For components having the same function and operation as the printed materials 100 of Embodiments 1 to 5, the same reference numerals are used, and their descriptions are omitted. Furthermore, Figure 28 The white arrow shown indicates the light passing through the aperture 112. Hereinafter, using... Figure 27 and Figure 28 The structure of Embodiment 7 will be described focusing on the differences from Embodiments 1 to 6. Furthermore, any structures not described in Embodiment 7 are the same as those in Embodiments 1 to 6.

[0166] The solar cell system 700 includes: a printed material 100 disposed on the light-receiving side; and a solar cell 600 disposed facing the printed material 100 and generating electricity by transmitting light through a plurality of holes 112 in the printed material 100.

[0167] The printed material 100 is the printed material 100 of Embodiment 1. The printed material 100 is used to decorate the solar cell 600, etc. The printed material 100 includes: a printed layer 110 having ink portions 111 made of printed ink and having a plurality of holes 112 for light to pass through; and a substrate 120 on which the printed layer 110 is printed.

[0168] like Figure 28 As shown, the substrate 120 of Embodiment 7 is a transparent component that allows light to pass through, and it is a transparent substrate on which a printed layer 110 is printed. The substrate 120 of Embodiment 7 is, for example, a synthetic resin or glass, but is not limited to this material. The substrate 120 can be a plate-shaped component or a film-shaped component such as a thin film. In addition, the substrate 120 can be not only a planar component, but also a three-dimensional curved component. Figure 28 The white arrows shown indicate the transmission of light. (As...) Figure 28 As shown, light passes through multiple apertures 112 and then through the printed layer 110.

[0169] Figure 28 The white arrows shown indicate the transmission of light. (As...) Figure 28 As shown, light passes through multiple apertures 112 and then through the printed layer 110. Light shining from the surface of the solar cell system 700 onto the solar cell 600 passes through multiple apertures 112 of the printed layer 110, and the light received by the solar cell 600 passes through the multiple apertures 112 and then through the printed layer 110 and the substrate 120 to reach the solar cell 600.

[0170] As an example, solar cell 600 is a perovskite solar cell, but it is not limited to perovskite solar cells. Perovskite solar cells have strong resistance to deformation and can achieve lightweight design, thus allowing them to be installed in locations where silicon solar cells have been unable to be installed until now. Therefore, when solar cell 600 is a perovskite solar cell, solar cell system 700 can install solar cell 600 in locations where silicon solar cells have been unable to be installed until now, while still utilizing the design and other functions of printed layer 110.

[0171] [The effects of printed materials]

[0172] The solar cell system 700 includes: a printed material 100 disposed on the light-receiving side; and a solar cell 600 disposed facing the printed material 100 and generating electricity through light passing through a plurality of apertures 112 in the printed material 100. The substrate 120 is a transparent substrate with a transparent, light-transmitting component and a printed layer 110 printed on its surface. Even when the printed material 100 has an ink portion 111 forming a decorative layer for design or various functions, light can still pass through the printed layer 110 through the plurality of apertures 112, thus enabling the solar cell 600 to generate electricity. By mounting the printed material 100 onto the solar cell 600, the solar cell system 700 can generate electricity in a manner that effectively utilizes the design of the printed material 100.

[0173] The present disclosure has been described above based on the embodiments, but the present disclosure is not limited to the structure of the above-described embodiments. In particular, the combination of constituent elements is not limited to the combination in the embodiments and can be appropriately modified.
