[0002] This application claims priority and benefits of the patent application with patent application number 202323081150.3 filed with the State Intellectual Property Office of China on November 14, 2023 and the patent application with patent application number 202323236472.0 filed with the State Intellectual Property Office of China on November 27, 2023, and the entire text of which is incorporated herein by reference. Technical Field
[0003] The present application relates to the technical field of solar cells, and in particular to a solar module and a solar curtain wall. Background Art
[0004] In the prior art, solar modules capable of generating electricity on both sides are usually designed in black or white, which are relatively monotonous in color and difficult to meet the user's requirements for aesthetics. Therefore, it is necessary to propose a solar module with color.
[0005] Summary of the Invention
[0006] This application aims to solve at least one of the technical problems existing in the prior art or related art.
[0007] To this end, the first object of the present application is to provide a solar module.
[0008] The second purpose of this application is to provide a solar curtain wall.
[0009] To achieve at least one of the above-mentioned purposes, according to the first aspect of the present application, a solar cell module is proposed, comprising: a cell layer, the cell layer comprising a first receiving surface and a second receiving surface, the first receiving surface and the second receiving surface being capable of receiving light; a first packaging component, arranged on the first receiving surface, the first packaging component being capable of transmitting light; a second packaging component, arranged on the second receiving surface, the second receiving surface being capable of transmitting light, the second packaging component comprising at least one colored light-transmitting adhesive film layer capable of displaying color.
[0010] The solar module proposed in this application includes a cell layer, a first packaging assembly, and a second packaging assembly. The cell layer is used to receive light and convert light energy into electrical energy, and the first packaging assembly and the second packaging assembly are used to protect the cell layer. Specifically, the cell layer has a first receiving surface and a second receiving surface. The first receiving surface can be the front side of the cell layer, and the second receiving surface can be the back side of the cell layer. Both the first receiving surface and the second receiving surface can receive light. In this way, the cell layer can have the function of bifacial power generation, thereby improving the power generation efficiency of the cell layer and, in turn, the power generation efficiency of the solar module.
[0011] Furthermore, a first packaging component is provided on the first receiving surface. Specifically, the first packaging component is mounted on the first receiving surface and is light-transmissive. Light can pass through the first packaging component and be transmitted to the first receiving surface. Thus, on the one hand, the first packaging component can protect the first receiving surface of the battery cell layer. On the other hand, since the first packaging component is light-transmissive, the first receiving surface of the battery cell layer can normally receive light, thereby not affecting the power generation effect of the battery cell layer.
[0012] Furthermore, a second packaging component is installed on the second receiving surface. The second packaging component is light-transmitting, and light can be transmitted to the second receiving surface through the second packaging component. In this way, on the one hand, the second receiving surface of the battery cell layer can be protected by the second packaging component. On the other hand, since the second packaging component is light-transmitting, the second receiving surface of the battery cell layer can receive light normally, thereby not affecting the power generation effect of the battery cell layer.
[0013] Furthermore, the second packaging component includes at least one color-transparent adhesive film layer capable of displaying colors. In this way, the solar module can display colors, improve the aesthetics of the solar module, and meet the various usage needs of users.
[0014] The solar module described above in this application may also have the following distinguishing technical features:
[0015] In some technical solutions, optionally, the second packaging component includes: a first color translucent adhesive film layer, which is capable of transmitting light and displaying colors; and a packaging backplane, which is capable of transmitting light; wherein the battery cell layer, the first color translucent adhesive film layer and the packaging backplane are stacked in sequence.
[0016] In this technical solution, a second packaging component is defined. Specifically, the second packaging component includes a first colored light-transmitting adhesive film layer and an encapsulation backplane. Both the first colored light-transmitting adhesive film layer and the encapsulation backplane are light-transmitting. This allows light to penetrate the encapsulation backplane and the first colored light-transmitting adhesive film layer and reach the second receiving surface of the solar cell layer, allowing the solar cell layer to properly receive light and convert the light energy into electrical energy, thereby enabling the solar panel to generate electricity normally.
[0017] Furthermore, the first colored light-transmitting adhesive film layer can display color. Since the encapsulation backsheet is light-transmitting, the color of the first colored light-transmitting adhesive film layer can be displayed to the outside world. In this way, the solar panel can display color, improving the aesthetics of the solar panel and meeting the various usage needs of users.

By limiting the thickness of the second color light-transmitting adhesive film layer within the above-mentioned size range, the strength of the second color light-transmitting adhesive film layer can meet the requirements, and the strength of the second packaging component can meet the protection requirements for the battery cell layer. By limiting the transmittance of the second color light-transmitting adhesive film layer within the above-mentioned range, the transmittance of the second packaging component can meet the light transmission requirements, and the battery cell layer can receive sufficient light. In addition, by limiting the thickness of the first waterproof layer within the above-mentioned size range, on the one hand, the waterproof requirements of the product can be met, and on the other hand, the thickness of the product can be avoided from being too large.
[0034] In a possible technical solution, the thickness of the second colored light-transmitting adhesive film layer is 0.6 mm, the thickness of the first waterproof layer is 35 μm, and the light transmittance of the second colored light-transmitting adhesive film layer is 50%.

[0079] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.
[0080] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.
[0081] Implementation method one:
[0082] The following describes a solar module 100 and a solar curtain wall provided according to some embodiments of the present application with reference to FIG. 1 to FIG. 6 .
[0083] In one embodiment of the present application, as shown in Figures 1, 2, 3, 4, 5 and 6, the present application proposes a solar module 100, including: a cell layer 110, the cell layer 110 including a first receiving surface 111 and a second receiving surface 112, the first receiving surface 111 and the second receiving surface 112 being capable of receiving light; a first packaging component 120, provided on the first receiving surface 111, the first packaging component 120 being capable of transmitting light; a second packaging component 130, provided on the second receiving surface 112, the second receiving surface 112 being capable of transmitting light, and the second packaging component 130 including at least one colored light-transmitting adhesive film layer 140 capable of displaying color.
[0084] The solar module 100 proposed in this application includes a cell layer 110, a first packaging component 120, and a second packaging component 130. The cell layer 110 is used to receive light and convert light energy into electrical energy, and the first packaging component 120 and the second packaging component 130 are used to protect the cell layer 110. Specifically, the cell layer 110 has a first receiving surface 111 and a second receiving surface 112. The first receiving surface 111 can be the front side of the cell layer 110, and the second receiving surface 112 can be the back side of the cell layer 110. Both the first receiving surface 111 and the second receiving surface 112 can receive light. In this way, the cell layer 110 can have the function of bifacial power generation, thereby improving the power generation efficiency of the cell layer 110, and thereby improving the power generation efficiency of the solar module 100.
[0085] Furthermore, the first packaging component 120 is provided on the first receiving surface 111. Specifically, the first packaging component 120 is installed on the first receiving surface 111. The first packaging component 120 is light-transmissive, and light can pass through the first packaging component 120 to the first receiving surface 111. In this way, on the one hand, the first packaging component 120 can protect the first receiving surface 111 of the battery layer 110. On the other hand, because the first packaging component 120 is light-transmissive, the first receiving surface 111 of the battery layer 110 can normally receive light, thereby not affecting the power generation effect of the battery layer 110.
[0086] Furthermore, the second packaging component 130 is installed on the second receiving surface 112. The second packaging component 130 is light-transmissive, and light can be transmitted to the second receiving surface 112 through the second packaging component 130. In this way, on the one hand, the second receiving surface 112 of the battery layer 110 can be protected by the second packaging component 130. On the other hand, since the second packaging component 130 is light-transmissive, the second receiving surface 112 of the battery layer 110 can receive light normally, and therefore will not affect the power generation effect of the battery layer 110.
[0087] Furthermore, the second packaging component 130 includes at least one color-transmissive adhesive film layer 140 capable of displaying colors. In this way, the solar module 100 can display colors, thereby improving the aesthetics of the solar module 100 and meeting various user needs.
[0088] In some embodiments, optionally, as shown in Figures 1 and 4, the second packaging component 130 includes: a first color translucent adhesive film layer 141, which is capable of transmitting light and displaying color; a packaging backplane 131, which is capable of transmitting light; wherein the battery cell layer 110, the first color translucent adhesive film layer 141 and the packaging backplane 131 are stacked in sequence.
[0089] In this embodiment, the second encapsulation component 130 is defined. Specifically, the second encapsulation component 130 includes a first colored light-transmitting adhesive film layer 141 and an encapsulation backsheet 131. Both the first colored light-transmitting adhesive film layer 141 and the encapsulation backsheet 131 are light-transmitting. This allows light to penetrate the encapsulation backsheet 131 and the first colored light-transmitting adhesive film layer 141 and reach the second receiving surface 112 of the solar cell layer 110, allowing the solar cell layer 110 to properly receive light and convert the light energy into electrical energy, thereby enabling the solar module 100 to properly generate electricity.
[0090] Furthermore, the first colored light-transmitting adhesive film layer 141 is capable of displaying color. Since the encapsulation backsheet 131 is light-transmitting, the color of the first colored light-transmitting adhesive film layer 141 can be displayed to the outside world. This allows the solar module 100 to display color, enhancing the aesthetics of the solar module 100 and meeting various user needs.
[0091] In a possible embodiment, the first colored light-transmitting adhesive film layer 141 is made of colored light-transmitting PVB, and the packaging backplane 131 is made of transparent PET.
[0092] In some embodiments, optionally, the thickness of the first color translucent adhesive film layer 141 ranges from 0.3 mm to 0.8 mm, the transmittance of the first color translucent adhesive film layer 141 ranges from 30% to 70%, and the thickness of the packaging backplane 131 ranges from 0.3 mm to 0.6 mm.
[0093] In this embodiment, the first colored light-transmitting adhesive film layer 141 and the encapsulation backsheet 131 are sized and specified. Specifically, the thickness of the first colored light-transmitting adhesive film layer 141 ranges from 0.3 mm to 0.8 mm, the transmittance of the first colored light-transmitting adhesive film layer 141 ranges from 30% to 70%, and the thickness of the encapsulation backsheet 131 ranges from 0.3 mm to 0.6 mm. By limiting the thickness of the first colored light-transmitting adhesive film layer 141 and the encapsulation backsheet 131 to the aforementioned size ranges, and limiting the transmittance of the first colored light-transmitting adhesive film layer 141 to the aforementioned ranges, the transmittance of the first encapsulation assembly 120 can meet the required light transmission, allowing the cell layer 110 to receive sufficient light. Furthermore, the strength of the first colored light-transmitting adhesive film layer 141 and the encapsulation backsheet 131 can meet the required strength, ensuring that the strength of the second encapsulation assembly 130 meets the required protection for the cell layer 110.

[0096] In this embodiment, the structure of the first packaging component 120 is defined. The first packaging component 120 includes an encapsulation glass layer 121 and a first encapsulation film layer 124, wherein the thickness of the encapsulation glass layer 121 ranges from 1.6 mm to 3.2 mm, and the thickness of the first encapsulation film layer 124 ranges from 0.4 mm to 0.8 mm. The encapsulation glass layer 121, the first encapsulation film layer 124, and the battery cell layer 110 are stacked in sequence. By limiting the thickness of the encapsulation glass layer 121 and the first encapsulation film layer 124 to the above-mentioned size range, the strength of the encapsulation glass layer 121 and the first encapsulation film layer 124 can meet the requirements, so that the strength of the first packaging component 120 can meet the protection requirements for the battery cell layer 110.

[0101] In some embodiments, optionally, as shown in Figure 4, the second packaging component 130 also includes: a second color translucent adhesive film layer 142, which is translucent and can display color; a first waterproof layer 132, which is translucent and waterproof; wherein the battery layer 110, the first color translucent adhesive film layer 141, the packaging backplane 131, the second color translucent adhesive film layer 142 and the first waterproof layer 132 are stacked in sequence.
[0102] In this embodiment, another structure of the second packaging component 130 is defined.

Thus, light can penetrate the second colored light-transmitting adhesive film layer 142 and the first waterproof layer 132 and be transmitted to the second receiving surface 112 of the cell layer 110, allowing the cell layer 110 to properly receive light and convert light energy into electrical energy, thereby enabling the solar module 100 to properly generate electricity.
[0103] Furthermore, the second colored light-transmitting film layer 142 is capable of displaying color. Since the first waterproof layer 132 is light-transmitting, the colors of the first and second colored light-transmitting film layers 141, 142 can be displayed to the outside world. This allows the solar module 100 to display color, enhancing its aesthetics and meeting various user needs.
[0104] In a possible embodiment, the second colored light-transmitting adhesive film layer 142 is made of colored light-transmitting PVB, and the first waterproof layer 132 is made of a fluorine-containing polymer film material, specifically, one of PVDF film, PVF film, or ETFE film.

By limiting the thickness of the second colored light-transmitting film layer 142 within these dimensional ranges, the strength of the second colored light-transmitting film layer 142 meets the required strength, ensuring that the strength of the second packaging assembly 130 meets the required protection for the cell layer 110. By limiting the transmittance of the second colored light-transmitting film layer 142 within these dimensional ranges, the transmittance of the second packaging assembly 130 meets the required light transmission, allowing the cell layer 110 to receive sufficient light. Furthermore, by limiting the thickness of the first waterproof layer 132 within these dimensional ranges, the product's waterproof requirements are met while preventing excessive thickness.
[0107] In a possible embodiment, the thickness of the second colored light-transmitting adhesive film layer 142 is 0.6 mm, the thickness of the first waterproof layer 132 is 35 μm, and the light transmittance of the second colored light-transmitting adhesive film layer 142 is 50%.

Specifically, the first color-transmitting adhesive film layer 141 and the second color-transmitting adhesive film layer 142 are the same color. This allows the appearance and color of the solar module 100 to remain consistent, improving the product's aesthetics.

By limiting the thickness of the second waterproof layer 123, the second encapsulating film layer 126, the encapsulating front plate 125, and the third encapsulating film layer 122 to within the aforementioned ranges, the strength of the first encapsulating assembly 120 can be ensured to meet the protection requirements for the solar cell layer 110, while also preventing the product from being too thick.

[0122] Implementation method 2:
[0123] Example 1:
[0124] As shown in Figures 7 and 8, this embodiment provides a solar module, which belongs to a portable solar device. A solar module includes: a second waterproof layer 121, a second encapsulation film layer 126, an encapsulation glass layer 121, a first encapsulation film layer 124, a battery layer 110, a first color transparent film layer 141 and an encapsulation backplane 131, which are stacked in sequence from the front to the back. The first encapsulation film layer 124 bonds the encapsulation glass layer 121 and the battery layer 110, and the first color transparent film layer 141 bonds the encapsulation backplane 131 and the battery layer 110. The second waterproof layer 121 is bonded to the side of the encapsulation glass layer 121 away from the battery layer 110 through the second encapsulation film layer 126. The front and back sides of the battery layer 110 are both provided with power generation surfaces. The second waterproof layer 121, the encapsulation glass layer 121 and the encapsulation backplane 131 all allow light to penetrate.
[0125] Furthermore, the first encapsulation film layer 124 and the second encapsulation film layer 126 are both configured as transparent films, and the first color light-transmitting film layer 141 is configured as a color light-transmitting film.
[0126] Specifically, on the front side of the cell layer 110, external light can directly penetrate the encapsulating glass layer 121 and the first encapsulating film layer 124. On the back side of the cell layer 110, because the first colored light-transmitting film layer 141 is a colored light-transmitting film, it visually blocks the back structure of the cell layer 110, maintaining aesthetics, while also allowing incident light to pass through the back side of the solar module, allowing the back side power generation surface of the cell layer 110 to receive incident light, thereby improving power generation efficiency. Furthermore, the second waterproof layer 121, the second encapsulating film layer 126, the encapsulating glass layer 121, the first encapsulating film layer 124, the cell layer 110, the first colored light-transmitting film layer 141, and the encapsulating backsheet 131 can be directly laminated, eliminating the need for an additional back light-transmitting structure for the cell layer 110. This reduces the manufacturing cost of conventional cell layer 110.
[0127] Exemplarily, the second waterproof layer 121 is made of a fluorine-containing polymer film material, preferably one of PVDF (polyvinylidene fluoride) film, PVF (polyvinyl fluoride resin) film or ETFE (copolymer of ethylene and tetrafluoroethylene) film. While effectively preventing moisture from entering the interior of the solar module, it can also resist wear and scratches during daily use, effectively extending the service life of the solar module.
[0128] Exemplarily, the thickness of the second waterproof layer 121 is 25 μm-45 μm.
[0129] For example, the second packaging film layer 126 is preferably made of transparent EVA (copolymer of ethylene and vinyl acetate) material, which is a highly light-transmitting film with a thickness of 0.3 mm to 0.7 mm.
[0130] Exemplarily, the encapsulation glass layer 121 is made of transparent PET (polyethylene terephthalate) or EPE (expanded polyethylene plastic) film material.
[0131] Exemplarily, the thickness of the encapsulation glass layer 121 is 0.25 mm-0.7 mm.
[0132] Exemplarily, the first packaging film layer 124 is made of EVA material, POE (copolymer of ethylene and octene) material or a co-extruded film material of EVA and POE, and is a highly light-transmitting film.
[0133] Exemplarily, the thickness of the first packaging film layer 124 is 0.4 mm-0.7 mm.
[0134] For example, as shown in Figures 7 and 8, the cell layer 110 includes a bifacial power generation unit 310, which includes a plurality of bifacial cells 301 electrically connected to each other through welding ribbons. The welding ribbons are located on the back side of the bifacial cell 301, and the first colored light-transmitting adhesive film layer 141 blocks the welding ribbons from the back side to maintain aesthetics.
[0135] Exemplarily, bifacial cell 301 employs a back-contact cell with no metal grid lines on the front side and positive and negative metal electrodes extending from the back side, such as an IBC (interdigitated back contact) cell, a TBC (tunnel oxide barrier contact) cell, an HPBC (high-efficiency back contact) cell, or an ABC (all-back contact) cell. As shown in FIG7 , no metal grid lines, positive and negative metal electrodes, or soldering ribbons are exposed on the front side of the solar module. On the back side of the solar module, the first colored light-transmitting adhesive film layer 141 shields the metal grid lines, positive and negative metal electrodes, and soldering ribbons from being exposed, thereby improving the aesthetics.
[0136] Illustratively, the first color-transparent adhesive film layer 141 is made of a color-transparent EVA material or PVB (polyvinyl butyral) material, which exhibits excellent light transmittance, flexibility, and weather resistance. The color-transparent EVA or PVB material is formed by mixing a masterbatch during the manufacturing process. The manufacturing process and material composition are well-known in the art and will not be further described here.
[0137] Exemplarily, the thickness of the first color light-transmitting adhesive film layer 141 is 0.3 mm-0.8 mm.

[0139] Exemplarily, the packaging back plate 131 is a transparent PET reinforced plate with high light transmittance, high strength, high weather resistance and good processing performance.
[0140] Exemplarily, as shown in FIG7 , the solar module further includes an outer frame 900 , which is fixed to the periphery of the solar module and covers the edges of the internal laminate structure to support and protect the edges of the solar module.

The solar module provided in this embodiment can be expanded or folded by rotating the solar module to improve portability and flexibility, and the bifacial cell 301 is placed in the hollow portion within the rigid frame 302 to enhance physical protection of the bifacial cell 301, thereby improving reliability.
[0144] In this embodiment, as shown in FIG. 9 , four bifacial power generation units 310 are provided.
[0145] Exemplarily, as shown in FIG10 , the encapsulation glass layer 121 and the first encapsulation film layer 124 are both arranged in one-to-one correspondence with the bifacial power generation unit 310 , and the back side of the first encapsulation film layer 124 is bonded to the hard frame 302 and the bifacial cell 301 .

[0147] Exemplarily, as shown in Figure 10, the bifacial power generation unit 310 also includes a third adhesive layer 303 and a second transparent back plate 304. The third adhesive layer 303 and the second transparent back plate 304 are both arranged in the hollow portion. The third adhesive layer 303 bonds the second transparent back plate 304 and the bifacial battery cell 301. The second transparent back plate 304 supports the bifacial battery cell 301. The third adhesive layer 303 is set as a colored translucent adhesive film to enhance the visual shielding of the back of the bifacial battery cell 301.
[0148] Of course, in other embodiments, the third adhesive layer 303 may also be made of a high-transmittance adhesive film.
[0149] Exemplarily, the light transmittance of the third adhesive layer 303 is 30% to 70%.
