Description

[Technical Field]

[0001] The present invention relates to a solar cell module and a solar cell panel. [Background technology]

[0002] Solar cell modules having perovskite solar cell elements that convert solar light energy into electrical energy are fixed to mounting surfaces such as roofs or walls of buildings or vehicle bodies and used (see, for example, Patent Documents 1 to 3).

[0003] Patent Document 1 describes a solar cell module that is fixed to a mounting base by a frame that can press the outer periphery of the solar cell module. The frame has a flange for pressing the outer periphery and legs that can be fixed to the mounting base, and the cross section of the frame is such that the flange and legs are continuously connected in a roughly inverted L-shape.

[0004] Patent Document 2 describes a solar cell module that is provided with a fixing part having a nut that can be fixed to a mounting part on the surface opposite to the light-receiving surface of the solar cell module. The fixing part has a protrusion that penetrates the sealing material that seals the solar cell and abuts against the glass substrate.

[0005] Patent Document 3 describes a solar cell module equipped with a reinforcing member embedded in the outer periphery of a sealing material (a light-transmitting substrate in Patent Document 3) that seals the solar cells. The reinforcing member has a mounting hole formed therein for fixing the solar cell module to a mounting portion. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-311281 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-162608 [Patent Document 3] Japanese Patent Application Laid-Open No. 2007-300086 Summary of the Invention [Problem to be solved by the invention]

[0007] Since the frame described in Patent Document 1 is a separate part from the solar cell module, the number of parts and labor required to install the solar cell module on the mounting portion increases, making it impossible to perform the installation work efficiently.

[0008] In the solar cell module described in Patent Document 2, the fixing part is bonded to the sealing material by a protrusion that penetrates the sealing material, but because the area of ​​the protrusion relative to the sealing material is small, the adhesive strength is low and there is a risk that the bond strength between the solar cell module and the mounting part cannot be maintained over a long period of time. Also, because the fixing part is provided on the surface opposite to the light-receiving surface, the installation work of the solar cell module cannot be carried out efficiently.

[0009] In the solar cell module described in Patent Document 3, the mounting hardware penetrates the first and second protective layers that cover the encapsulant, so there is a risk that the first and second protective layers will be gouged out by the rotational torque of the mounting hardware. Furthermore, there is a risk that the adhesive on the protective layers will peel off due to the axial force of the bolts, causing lift around the reinforcing member and reducing the bonding strength between the solar cell module and the mounting portion.

[0010] The present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide a solar cell module and a solar cell panel that are easy to attach to the attachment portion and that can maintain the bonding strength between the solar cell module and the attachment portion. [Means for solving the problem]

[0011] A solar cell module according to the present invention is characterized in that it comprises a solar cell having a perovskite solar cell element, a sealing material that seals the solar cell, a first protective layer that protects a first surface of the sealing material, a second protective layer that protects a second surface opposite the first surface, and a mounting member for installation, wherein the mounting member has an embedded portion embedded in the sealing material and a protruding portion that protrudes outward from the sealing material and is fixed to a mounting portion.

[0012] According to this configuration, the mounting member is fixed to the solar cell module by the embedded portion embedded in the sealing material, and the solar cell module can be fixed to the mounting base via the mounting member by the protruding portion protruding outward from the sealing material. This makes it possible to efficiently install the solar cell module. Furthermore, when the protruding portion is fixed to the mounting base with a bolt or the like, the bolt or the like does not penetrate the first protective layer or the second protective layer, which prevents damage to the protective layer due to rotational torque or axial force and suppresses a decrease in the bond strength between the mounting member and the mounting base.

[0014] First Embodiment Hereinafter, embodiments of a solar cell module 200 and a solar cell panel 300 according to the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments, and various modifications are possible without departing from the spirit of the present invention.

[0015] [Schematic configuration of solar cell module] As shown in Fig. 1, the solar cell module 200 includes a solar cell 100, a sealing material 5, a first protective layer 6, and a second protective layer 7. The solar cell 100 is made up of a plurality of solar cell cells 10 electrically connected together. The solar cell 10 is made up of a substrate 1, a conductive layer 2, a perovskite solar cell element 3, and an electrode 4 laminated in this order.

[0016] 〔substrate〕 The substrate 1 functions as a support for the perovskite solar cell element 3 and the electrode 4. The substrate 1 is a transparent glass substrate, a semi-transparent glass substrate, a transparent resin substrate, or the like, and has insulating properties. The substrate 1 has a rectangular shape when viewed along the Z direction.

[0017] As shown in FIG. 1, an electrically conductive layer 2 is laminated on a substrate 1. The orientation of the solar cell module 200 during use is not particularly limited, but it is preferable that light is incident on the Z2 side of the substrate 1, i.e., the side where the first protective layer 6 is provided. Hereinafter, the direction from the substrate 1 to the electrically conductive layer 2 will be referred to as the "Z1 direction" (an example of a lamination direction), the opposite direction will be referred to as the "Z2 direction," and the Z1 direction and the Z2 direction will be collectively referred to as the "Z direction." Furthermore, one of the directions perpendicular to the Z direction will be referred to as the "X direction," and the direction perpendicular to the Z direction and the X direction will be referred to as the "Y direction" (see FIG. 2). Note that FIG. 2 is a view of the solar cell module 200 shown in FIG. 1 as viewed along the Z2 direction.

[0018] [Conductive Layer] The conductive layer 2 is formed on the Z1 side surface of the substrate 1 by CVD (chemical vapor deposition), sputtering, or the like. In this embodiment, the conductive layer 2 is formed on the entire Z1 side surface of the substrate 1. The conductive layer 2 contains, for example, fluorine-doped tin oxide (FTO), tin oxide (TO), or the like as a material. The perovskite solar cell element 3 is disposed (stacked) on the conductive layer 2 (on the Z1 side surface).

[0019] [Perovskite solar cell element] The perovskite solar cell element 3 converts light energy into electrical energy. The perovskite solar cell element 3 has an electron transport layer 31, a photoelectric conversion layer 32, and a hole transport layer 33, which are arranged in this order along the Z1 direction. When viewed along the Z direction, the electron transport layer 31, the photoelectric conversion layer 32, and the hole transport layer 33 each have a rectangular shape, and in this embodiment, when viewed along the Z direction, the electron transport layer 31, the photoelectric conversion layer 32, and the hole transport layer 33 each have the same size (area).

[0020] The electron transport layer 31 is disposed on the Z1-side surface of the conductive layer 2. The electron transport layer 31 passes through (transports) electrons received from the photoelectric conversion layer 32 (described later). The electron transport layer 31 includes, as a material, a metal oxide such as titanium oxide, tin oxide, or zinc oxide. In this embodiment, the electron transport layer 31 includes an insulating layer 311 extending into the recess 21 formed by removing a portion of the conductive layer 2. The insulating layer 311 divides the conductive layer 2, which is in contact with the perovskite solar cell element 3, into two sections along the X direction. In the electron transport layer 31, electrons can move in the Z direction but have difficulty moving in directions perpendicular to the Z direction (the X and Y directions), restricting their movement between the two sections of the conductive layer 2 corresponding to each perovskite solar cell element 3. The electron transport layer 31 is sometimes referred to as a "blocking layer."

[0021] Since the substrate 1, the conductive layer 2, and the electron transport layer 31 are optically transparent, light such as sunlight and indoor light is guided to the photoelectric conversion layer 32 without being substantially absorbed (or without being absorbed) by the substrate 1, the conductive layer 2, and the electron transport layer 31.

[0022] The photoelectric conversion layer 32 absorbs light energy and converts it into electrical energy. Specifically, the photoelectric conversion layer 32 absorbs light and transfers excited electrons and holes to perform photoelectric conversion. The photoelectric conversion layer 32 includes a perovskite layer made of a perovskite compound. The photoelectric conversion layer 32 further includes a porous oxide semiconductor layer (for example, a porous titanium layer).

[0023] The hole transport layer 33 allows holes received from the photoelectric conversion layer 32 to pass through (transports holes). The hole transport layer 33 contains, for example, an organic compound such as chlorobenzene as a material. An electrode 4 is disposed on the hole transport layer 33 (on the Z1 side).

[0024] The electrode 4 is conductive and functions as a positive electrode. As shown in FIG. 1, the electrode 4 is disposed on (a part of) the Z1-side surface of the conductive layer 2, extending in the Z direction from the Z1-side surface of the hole transport layer 33, past each side surface of the perovskite solar cell element 3. The electrode 4 contains, for example, graphite, carbon black, carbon nanotubes, carbon nanofibers, carbon fibers, graphene, fullerene, or the like as a material. The electrode 4 may also be formed using a metal such as gold, platinum, silver, or copper, an alloy thereof, or an oxide conductor such as FTO or indium tin oxide (ITO).

[0025] A conductive layer 2, a perovskite solar cell element 3, and an electrode 4 are formed in this order on a substrate 1 to form a solar cell 10. In this embodiment, a plurality of solar cells 10 arranged along the X direction are electrically connected via the conductive layer 2 and the electrode 4.

[0026] [Sealing material] 1 and 2, the solar cell 100 is sealed with a sealing material 5. This shields the perovskite solar cell element 3 and the electrode 4 from the atmosphere, improving the durability of the solar cell module 200. The sealing material 5 is preferably a weather-resistant, transparent resin, and examples of materials that can be used include acrylic resin, polyvinyl chloride resin, polycarbonate, fluorine-based resin, silicone resin, and ethylene-vinyl acetate copolymer resin.

[0027] 1 and 2, the area of ​​the sealing material 5 in a plan view is larger than the area of ​​the solar cell 100. The sealing material 5 adheres to the solar cell 100 and covers the entire solar cell 100, thereby protecting the solar cell 100 from external stresses acting on the solar cell 100, etc.

[0028] [Protective layer] A first protective layer 6 is provided on a first surface 5A, which is the surface on the Z2 side of the sealing material 5, and a second protective layer 7 is provided on a second surface 5B, which is the surface on the Z1 side. The first protective layer 6 and the second protective layer 7 are adhered to the sealing material 5 and serve to prevent adhesion between the sealing material 5 and an external component. It is preferable that the areas of these layers in a plan view are substantially the same as the area of ​​the sealing material 5. The first protective layer 6 is made of, for example, a fluorine-based resin. The second protective layer 7 is made of, for example, a resin such as polyethylene terephthalate. Since light enters from the surface of the first protective layer 6 in the Z2 direction, it is preferable that the first protective layer 6 is transparent.

[0029] Light, such as sunlight, enters the solar cell module 200 from the Z2 side. The light enters the solar cell 100 through the first protective layer 6 and the encapsulant 5, and then reaches the photoelectric conversion layer 32 via the substrate 1, the conductive layer 2, and the electron transport layer 31. The light is absorbed by the photoelectric conversion layer 32, generating electrons and holes. The electrons generated in the photoelectric conversion layer 32 migrate to the conductive layer 2 (negative electrode) via the electron transport layer 31. At the same time, the holes generated in the photoelectric conversion layer 32 migrate to the electrode 4 (positive electrode) electrically connected to the hole transport layer 33. When a load (not shown) is connected between the conductive layer 2 and the electrode 4, the holes combine with the electrons that have traveled through the load. As a result, electricity is generated. Note that the electrons moving through the electron transport layer 31 move smoothly along the Z2 direction to reach the conductive layer 2, but as described above, the insulating layer 311 restricts their movement in a direction perpendicular to the Z direction. In other words, the solar cell module 200 is configured to prevent short circuits.

[0030] [Mounting parts] The solar cell module 200 is used by being attached to a mounting portion such as the roof or wall of a building or a vehicle. The solar cell module 200 according to this embodiment has a pair of mounting members 8, 8 for mounting to the mounting portion. As shown in FIGS. 1 and 2, the pair of mounting members 8, 8 are provided on both sides of the solar cell module 200 in the X direction. The mounting members 8 provided on each side in the X direction may be of the same shape. The mounting members 8 are preferably made of a lightweight weather-resistant material, and may be made of a metal such as aluminum, for example.

[0031] The mounting member 8 is flat and has an embedded portion 81 embedded in the sealing material 5 and a protruding portion 82 protruding outward from the sealing material 5. The protruding portion 82 has a plurality of through holes 84 (three in this embodiment) for fastening to the mounting portion. The solar cell module 200 can be mounted to the mounting portion by inserting a fastening member such as a rivet or a drill screw into the through holes 84 and fastening the protruding portion 82 to the mounting portion. Furthermore, because the fastening through holes 84 are provided outside the first protective layer 6, the second protective layer 7, and the sealing material 5, the fastening member does not come into contact with these. This prevents damage to the first protective layer 6 and the like due to the rotational torque or axial force of the fastening member.

[0032] The embedded portion 81 may have an adhesive structure that improves adhesion with the sealing material 5. The adhesive structure may be, for example, a roughened portion consisting of numerous microscopic protrusions formed on the surface of the embedded portion 81 by a surface roughening treatment, or holes formed in the surface of the embedded portion 81. The formation of the roughened portion or holes increases the contact area between the embedded portion 81 and the sealing material 5, thereby allowing the embedded portion 81 to adhere closely to the sealing material 5 and increasing the adhesive strength between them. The adhesive structure in this embodiment is a hole 83 formed in the surface of the embedded portion 81. The size of the hole 83 in the embedded portion 81 can be determined arbitrarily, but in order to improve the adhesive strength between the embedded portion 81 and the sealing material 5, it is preferable that the hole 83 occupies more than half of the surface area of ​​the embedded portion 81. By filling a portion of the sealing material 5 into the hole 83, the adhesiveness between the embedded portion 81 and the sealing material 5 is improved.

[0033] The dimension of the mounting member 8 in the Y direction is preferably smaller than the dimension of the sealing material 5 in the Y direction. The mounting member 8 is preferably disposed at a position spaced a predetermined distance from the solar cell 100. The dimensions of the embedded portion 81 and the protruding portion 82 in the X direction can be any value, but are preferably dimensions that ensure the bonding strength between the solar cell module 200 and the portion to be mounted. The dimension of the mounting member 8 in the Z direction is preferably 0.3 mm to 0.7 mm. If the dimension of the mounting member 8 in the Z direction is 0.3 mm or more, the strength of the mounting member 8 can be maintained, and if it is 0.7 mm or less, the thickness of the solar cell module 200 is not increased.

[0034] [Method for manufacturing solar cell module] Next, a description will be given of a method for manufacturing the solar cell module 200. The method for manufacturing the solar cell module 200 in this embodiment includes a step of forming the solar cells 100 and a step of sealing the solar cells 100.

[0035] First, in the step of forming the solar cell 100, a conductive layer 2 is formed on the Z1 side surface of the substrate 1. The conductive layer 2 may be formed by, for example, CVD (chemical vapor deposition) or sputtering. Next, laser scribing is performed to partially remove the conductive layer 2, forming recesses 21. Thereafter, a perovskite solar cell element 3 and an electrode 4 are formed on the Z1 side surface of the conductive layer 2 by a known method, thereby obtaining a solar cell 10. A plurality of solar cell cells 10 are formed, thereby obtaining a solar cell 100.

[0036] Next, as shown in FIG. 3 , the solar cell 100 and the mounting member 8 are placed on the Z1 side surface of the first sealing material 51 that forms the sealing material 5. A first protective layer 6 may be placed on the Z2 side surface of the first sealing material 51. The dimension of the first sealing material 51 in the Z direction may be, for example, 0.3 mm. The solar cell 100 may be placed on the first sealing material 51 after the mounting member 8 is positioned, or the mounting member 8 may be placed after the solar cell 100 is placed. The mounting member 8 may be positioned so that the hole 83 of the embedded portion 81 is located on the first sealing material 51. The mounting members 8, 8 placed on both sides in the X direction are preferably placed symmetrically with respect to the solar cell 100.

[0037] Next, the second sealing material 52 that forms the sealing material 5 is placed on the Z1-side surfaces of the solar cell 100 and the mounting member 8. A second protective layer 7 may be placed on the Z1-side surface of the second sealing material 52, and the area of ​​the second sealing material 52 in a plan view may be approximately the same as that of the first sealing material 51. The dimension of the second sealing material 52 in the Z direction may be, for example, 0.5 mm. After the second sealing material 52 is placed so as to overlap the first sealing material 51 in a Z-direction view, they are thermally welded together, whereby the first sealing material 51 and the second sealing material 52 melt and enter the spaces between the hole portion 83 and the embedded portion 81 and the solar cell 100. As a result, the solar cell 100 is sealed in the sealing material 5, and the embedded portion 81 is fixed to the sealing material 5.

[0038] [Solar panel] Next, a solar cell panel 300 having a plurality of solar cell modules 200 will be described with reference to Fig. 4. The solar cell panel 300 has a plurality of solar cell modules 200 (two in this embodiment).

[0039] The solar cell module 200 is arranged along the surface of the mounting portion W with the first protective layer 6 facing forward. Fig. 4 is a view of the solar cell panel 300 as viewed from the Z1 side (front). The solar cell module 200 is mounted to the mounting portion W by inserting fixing members R such as rivets into the through holes 84 of the mounting member 8 and fixing the solar cell module 200 to the mounting portion W.

[0040] When viewed from the front (viewing the solar cell panel 300 from the Z1 side), the protrusions 82, 82 of adjacent solar cell modules 200 are arranged so that their respective through holes 84, 84 overlap. Because the through holes 84 of adjacent solar cell modules 200 overlap, they can be fastened together, improving the efficiency of the installation work of the solar cell modules 200. Furthermore, the installation area of ​​the solar cell panel 300 on the mounting portion W can be reduced, thereby enabling space saving.

[0041] The method of installing the multiple solar cell modules 200 in the solar cell panel 300 is not particularly limited, but in terms of installing the solar cell modules 200 along the horizontal surface of the installation target W, it is preferable that the pair of protrusions 82, 82 of the solar cell modules 200 are arranged on the same plane. That is, it is preferable that the protrusions 82, 82 of an adjacent solar cell module 200 are arranged so as to overlap the Z1-side surfaces of the pair of protrusions 82, 82 of one solar cell module 200, and that the other protrusion 82 of the adjacent solar cell module 200 is arranged so as to overlap the Z1-side surface of the protrusion 82 of the adjacent solar cell module 200 on the opposite side to the one solar cell module 200.

[0042] Other Embodiments 5, the embedded portion 81 of the mounting member 8 may have a plurality of circular holes 85. By filling the plurality of holes 85 with the sealing material 5, the adhesive strength between the sealing material 5 and the mounting member 8 can be improved.

[0043] 6, the embedded portion 81 of the mounting member 8 may have a plurality of rectangular holes 86. By filling the plurality of holes 85 with the sealing material 5, the adhesive strength between the sealing material 5 and the mounting member 8 can be improved.

[0044] (c) In the above embodiment, the adhesion structure of the embedded portion 81 is formed by forming a roughened portion on the surface of the embedded portion 81 through a surface roughening treatment or by forming the hole 83, but the shape of the adhesion structure is not limited to these. Furthermore, the shape of the hole 83, 85, 86 is not limited to the above-described shapes and can be any shape. Furthermore, if the adhesion structure is a roughened portion, the adhesive strength between the embedded portion 81 and the sealing material 5 can be further increased by the so-called anchor effect.

[0045] (d) As shown in FIG. 7 , the protrusion 82 may have multiple notches 87. When viewed from the X direction, the notch 87 of the protrusion 82 protruding from one side of the sealing material 5 may overlap with the protrusion 82 protruding from the other side opposite the one side, and the notch 87 of the other protrusion 82 may overlap with one of the protrusions 82. When solar cell modules 200 having such protrusions 82 are arranged along the X direction with the first protective layer 6 facing forward, one protrusion 82 fits into the notch 87 of the other protrusion 82, and the other protrusion 82 fits into the notch 87 of the one protrusion 82. In other words, when viewed from the Y direction, the protrusions 82 of adjacent solar cell modules 200 overlap. This allows for a reduction in the installation area of ​​the solar cell panel 300 on the mounting portion W, thereby enabling space saving.

[0046] (e) In the above embodiment, the solar cell 100 is sealed with the sealing material 5, but it may be sealed with an adhesive having waterproof or gas barrier properties, or with an aluminum-deposited PET film, and then sealed with the sealing material 5. This can improve the durability of the solar cell module 200.

[0047] In the above-described embodiment, the following configurations are envisioned. (1) A solar cell module 200 comprising a solar cell 100 having a perovskite solar cell element 3, a sealing material 5 that seals the solar cell 100, a first protective layer 6 that protects a first surface 5A of the sealing material 5, a second protective layer 7 that protects a second surface 5B opposite to the first surface 5A, and a mounting member 8 for mounting, wherein the mounting member 8 has an embedded portion 81 embedded in the sealing material 5 and a protruding portion 82 that protrudes outward from the sealing material 5 and is fixed to a mounting portion.

[0048] According to this configuration, the mounting member 8 is fixed to the solar cell module 200 by the embedded portion 81 embedded in the sealing material 5, and the solar cell module 200 can be fixed to the mounting base W via the mounting member 8 by the protruding portion 82 protruding outward from the sealing material 5. This makes it possible to improve the efficiency of the mounting work of the solar cell module 200. Furthermore, when the protruding portion 82 is fixed to the mounting base W with a fixing member R such as a rivet, the fixing member R does not penetrate the first protective layer 6 or the second protective layer 7, so that damage to the protective layers 6 and 7 due to rotational torque or axial force can be prevented, and a decrease in the bonding strength between the mounting member 8 and the mounting base W can be suppressed.

[0049] (2) In the solar cell module 200 of (1), it is preferable that the protruding portion 82 has a through-hole 84 for fastening to the mounting portion W.

[0050] According to this configuration, the solar cell module 200 can be fixed to the mounting portion W by the fixing member R, which makes it easy to mount the solar cell module 200.

[0051] (3) In the solar cell module 200 of (1) or (2), the embedded portion 81 preferably has an adhesive structure that improves adhesiveness with the sealing material 5.

[0052] According to this configuration, it is possible to improve the adhesion between the embedded portion 81 and the sealing material 5, thereby increasing the adhesive strength between the mounting member 8 and the sealing material 5. This makes it possible to maintain the bond between the solar cell module 200 and the mounting portion W for a long period of time.

[0053] (4) A solar cell panel 300 having a plurality of solar cell modules 200 of any one of (1) to (3), wherein the plurality of solar cell modules 200 are arranged along the surface of the mounting portion W so that the first protective layer 6 is positioned at the front, and when viewed from the front, the protrusions 82 of adjacent solar cell modules 200 overlap each other.

[0054] According to this configuration, the protruding portions 82 of adjacent solar cell modules 200 overlap each other, making it possible to fasten the adjacent protruding portions 82 together. This reduces the installation area of ​​the mounting member 8, and makes it possible to save space on the fixing surface of the mounting portion W for the solar cell panel 300.
