Description

Technical Field

[0001] The utility model relates to the technical field of solar cells, in particular to a solar cell assembly. Background Art

[0002] The solar panels in the prior art are made of lightweight materials, which results in poor impact resistance of the solar panels and poor light transmittance on the back of the solar panels, thereby affecting the light reception on the back of the solar panels. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, the utility model proposes a solar energy component.

[0005] To achieve at least one of the above purposes, the utility model proposes a solar energy component, including: a solar cell, used to convert light energy into electrical energy, the solar cell having a first mounting surface and a second mounting surface that are opposite to each other, the first mounting surface being able to receive light; a first protective layer, located on one side of the first mounting surface, the first protective layer being able to transmit light; a second protective layer, located on one side of the second mounting surface; a support mesh, located between the second protective layer and the solar cell, the support mesh being used to support the solar cell, the support mesh having a plurality of mesh holes.

[0006] The solar cell module proposed in the present application includes a solar cell, a first protective layer, a second protective layer and a support net. The solar cell is capable of receiving light energy and converting the light energy into electrical energy to realize the power generation function of the solar cell module. Specifically, the solar cell has a first mounting surface and a second mounting surface, the first mounting surface and the second mounting surface are opposite to each other, the first mounting surface is capable of receiving light, and the solar cell is capable of converting the light energy into electrical energy after receiving the light. The first mounting surface may be the front of the solar cell, and the second mounting surface may be the back of the solar cell. In one possible technical solution, when the solar cell module is installed on an object such as a building, the first mounting surface of the solar cell faces the outside world, and the second surface of the solar cell faces the building, so that the solar cell can receive light normally. In another possible technical solution, the second mounting surface of the solar cell can also receive light, so that the solar cell module can generate electricity on both sides.

[0007] Furthermore, in order to protect the solar cell, the present application provides a first protective layer and a second protective layer on one side of the first mounting surface and one side of the second mounting surface of the solar cell, respectively. Specifically, the first protective layer is located on one side of the first mounting surface of the solar cell, and the first protective layer is light-transmissive, so that light can pass through the first protective layer and illuminate the first mounting surface, so that the solar cell can receive light normally. The second protective layer is located on one side of the second mounting surface of the solar cell, and the second protective layer can be light-transmissive or light-impermeable. When the second protective layer is light-transmissive, both the first mounting surface and the second mounting surface of the solar cell can receive light, and double-sided power generation of the solar module can be achieved. When the second protective layer is light-impermeable, only the first mounting surface of the solar cell can receive light, and the solar module is single-sided power generation.

[0008] Furthermore, in order to improve the overall strength of the solar module, the present application also provides a support net in the solar module. The support net is located between the second protective layer and the solar cell. The support net can be made of metal material or other high-strength materials. The support net can play a certain supporting role on both the solar cell and the first protective layer to improve the overall strength of the solar module. When the solar module is impacted, the deformation of the solar cell is reduced and the damage to the solar cell is reduced. The support net also has a plurality of mesh holes, so that the support net can be light-transmitting. When the solar module is a double-sided power generation product, the second mounting surface can receive light normally. In addition, by providing a support net between the solar cell and the second protective layer, the light reflection of the second protective layer can be reduced, so that the colors of the front and back sides of the solar module tend to be consistent.

[0009] The solar module described above according to the utility model may also have the following distinguishing technical features:

[0010] In some technical solutions, optionally, the supporting mesh includes: a plurality of metal wires, the plurality of metal wires are cross-arranged to define mesh holes, the intersection area between any two metal wires defines an intersection, any two metal wires are connected to each other at corresponding intersections, and the number of intersections corresponding to any mesh hole is greater than or equal to three.

[0011] In the technical solution, the structure of the support net is further defined. The support net includes a plurality of metal wires, and the plurality of metal wires are arranged to cross each other to define mesh holes. Any two crossed metal wires are connected to each other. Specifically, the intersection area between any two metal wires defines a cross section, and any two metal wires are connected to each other at the cross section formed between the two metal wires. The two metal wires can be connected by welding or by winding each other.

[0012] Furthermore, the number of intersections corresponding to any mesh is greater than or equal to three. Understandably, the more the number of intersections corresponding to each mesh, the more balanced the force on the multiple metal wires constituting the mesh, and the higher the pulling strength of the support mesh. In a possible technical solution, the number of intersections corresponding to any mesh is four, and the four intersections are evenly distributed along the circumference of the mesh, so that the mesh is uniformly stressed in the four directions of up, down, left and right, thereby increasing the overall pulling strength of the support mesh. Among them, the metal wire can be made of aluminum wire or aluminum alloy wire, or can be made of iron wire, steel wire or copper wire, and the surface of the metal wire can be sprayed with color. The thickness range of the support mesh is 0.2mm to 1.5mm.

[0013] In some technical solutions, optionally, the hole area of ​​all meshes in the supporting net is P1, the coverage area of ​​all metal wires in the supporting net is P2, and P1 and P2 satisfy P1 / (P1+P2)≥0.5.

[0014] In this technical solution, the support net is further defined. The hole area of ​​all meshes in the support net is P1, the coverage area of ​​all metal wires in the support net is P2, and P1 and P2 satisfy P1 / (P1+P2)≥0.5. In this way, the light-transmitting area of ​​the support net can meet the use requirements, and when both the first mounting surface and the second mounting surface of the solar cell can receive light, the second mounting surface of the solar cell can receive sufficient light, reducing the light blocking by the support net and improving the power generation efficiency of the solar module.

[0015] In some technical solutions, optionally, the solar module further includes: an insulating layer, located between the supporting mesh and the solar cell sheet, and the insulating layer is capable of insulation.

[0016] In this technical solution, the solar module is further defined. The solar module also includes an insulating layer, and the insulating layer is made of an insulating material so that the insulating layer can be insulated. The insulating layer is located between the supporting mesh and the solar cell. Since the supporting mesh is made of a metal material, if the solar cell is in direct contact with the supporting mesh, there is a possibility of leakage or short circuit. In order to avoid the above problems, the present application sets an insulating layer between the solar cell and the supporting mesh, thereby avoiding the problems of leakage and short circuit. The insulating layer can be made of PET (polyethylene terephthalate). When the solar module is a single-sided power generation product, the insulating layer can be opaque, and when the solar module is a double-sided power generation product, the insulating layer is transparent. The thickness of the insulating layer ranges from 0.1mm to 0.8mm.

[0017] In some technical solutions, optionally, the solar panel also includes: a first adhesive layer, located between the first protective layer and the solar cell, the first adhesive layer is used to bond the first protective layer and the solar cell, and the first adhesive layer is light-transmissive; a second adhesive layer, located between the solar cell and the insulating layer, the second adhesive layer is used to bond the solar cell and the insulating layer; a third adhesive layer, located between the insulating layer and the supporting mesh, the third adhesive layer is used to bond the supporting mesh and the insulating layer; a fourth adhesive layer, located between the supporting mesh and the second protective layer, the fourth adhesive layer is used to bond the supporting mesh and the second protective layer.

[0018] In this technical solution, the solar module is further defined. In order to enable the first protective layer, the solar cell, the insulating layer, the support net and the second protective layer to be connected in sequence to form a whole, the present application also provides multiple adhesive layers in the solar module. Specifically, a first adhesive layer is provided between the first protective layer and the solar cell, and the first adhesive layer is used to bond the first protective layer and the solar cell. Further, the first adhesive layer can be light-transmissive, so that the light can pass through the first adhesive layer to the first mounting surface, so that the solar cell can receive the light normally. A second adhesive layer is provided between the solar cell and the insulating layer, and the second adhesive layer is used to bond the solar cell and the insulating layer. A third adhesive layer is provided between the insulating layer and the support net, and the third adhesive layer is used to bond the insulating layer and the support net. A fourth adhesive layer is provided between the support net and the second protective layer, and the fourth adhesive layer is used to bond the support net and the second protective layer. By providing the first adhesive layer, the second adhesive layer, the third adhesive layer and the fourth adhesive layer in the solar module, the first protective layer, the solar cell, the insulating layer, the support net and the second protective layer can be connected in sequence to form a whole.

[0019] In a possible technical solution, the first adhesive layer, the second adhesive layer, the third adhesive layer and the fourth adhesive layer are a kind of adhesive film having adhesive properties by melting at high temperature, and specifically may include one or more of EVA (ethylene-vinyl acetatecopolylmer), POE (polyolefin thermoplastic elastomer) or PVB (polyvinyl butyral) materials.

[0020] In some technical solutions, optionally, the thickness of the supporting mesh is H1, the thickness of the third adhesive layer is H2, the thickness of the fourth adhesive layer is H3, and H1, H2 and H3 satisfy H1≤H2+H3.

[0021] In this technical solution, the thickness relationship between the support mesh, the third adhesive layer and the fourth adhesive layer is defined. Specifically, the thickness of the support mesh is H1, the thickness of the third adhesive layer is H2, and the thickness of the fourth adhesive layer is H3, and H1, H2 and H3 satisfy H1≤H2+H3. It can be understood that the third adhesive layer is used to bond the support mesh and the insulating layer, and the fourth adhesive layer is used to bond the support mesh and the second protective layer. If the thickness of the third adhesive layer and the fourth adhesive layer is too thin, it will cause the support mesh to be not firmly bonded to the insulating layer and the second protective layer. By limiting the sum of the thickness of the third adhesive layer and the thickness of the fourth adhesive layer to be greater than or equal to the thickness of the support mesh, it can be ensured that the third adhesive layer and the fourth adhesive layer can firmly bond the support mesh to the insulating layer and the second protective layer.

[0022] In some technical solutions, optionally, the solar panel also includes: a supporting frame, located between the first protective layer and the insulating layer, the supporting frame having a receiving groove, the solar cell being located in the receiving groove, the first adhesive layer being also used to bond the supporting frame to the first protective layer, and the second adhesive layer being also used to bond the supporting frame to the insulating layer.

[0023] In this technical solution, the structure of the solar module is further defined. The solar module may also include a support frame, which is used to improve the overall strength of the solar module. Specifically, the support frame is located between the first protective layer and the insulating layer, the support frame has a receiving groove, the solar cell is located in the receiving groove, and the support frame surrounds the circumference of the solar cell, so that the solar cell can be protected by the support frame. The support frame is bonded to the first protective layer through a first adhesive layer, and is bonded to the insulating layer through a second adhesive layer. The support frame can be made of one or more materials selected from glass fiber board, epoxy resin, polyurethane, synthetic resin, metal or carbon fiber board.

[0024] By providing a support frame in the solar module, on the one hand, the overall strength of the solar module can be improved, and on the other hand, it can provide a certain degree of protection for the solar cell panels.

[0025] In some technical solutions, optionally, the edge of the support frame protrudes from the edge of the support net, or the edge of the support frame is flush with the edge of the support net.

[0026] In this technical solution, the positional relationship between the support frame and the support net is defined. Specifically, the edge of the support frame protrudes from the edge of the support net, or the edge of the support frame is flush with the edge of the support net. Understandably, if the support net protrudes from the edge of the support frame, on the one hand, it will make it difficult to trim the edges when cutting solar panels, and on the other hand, it will cause sharp protrusions on the edges of the solar panels, which may easily cause safety accidents. In order to avoid the above-mentioned problems, the present application sets the edge of the support frame to protrude from the edge of the support net, or makes the edge of the support frame flush with the edge of the support net, thereby avoiding the support net protruding from the edge of the support frame, so as to facilitate the trimming of solar panels and avoid protruding sharp points on solar panels, thereby improving the safety of the product.

[0027] In some technical schemes, optionally, the first protective layer includes: a first texture layer, the surface of the first texture layer has texture; a first protective plate; a fifth adhesive layer, used to bond the first texture layer and the first protective plate, along the direction toward the solar cell, the first texture layer, the fifth adhesive layer and the first protective plate are stacked in sequence, and the first texture layer, the first protective plate and the fifth adhesive layer are light-transmissive.

The first protective layer includes a first texture layer, a first protective plate and a fifth adhesive layer, wherein the fifth adhesive layer is located between the first texture layer and the first protective plate, and the fifth adhesive layer is used to bond the first texture layer and the first protective plate. In the direction toward the solar cell, the first texture layer, the fifth adhesive layer and the first protective plate are stacked in sequence, that is, the first texture layer is arranged toward the outside, and the first protective plate is arranged toward the solar cell.

[0029] Furthermore, the surface of the first texture layer has texture, and because the textured surface of the first texture layer is arranged to face the outside, on the one hand, the rainwater can be diverted through the texture, which is conducive to the rapid discharge of rainwater outside the solar module, and on the other hand, the aesthetics of the solar module can be improved. The first protective plate and the first texture layer can further protect the solar cell. The first texture layer, the first protective plate and the fifth adhesive layer are all light-transmissive, so that light can pass through the first texture layer, the first protective plate and the fifth adhesive layer to the first mounting surface of the solar cell, so that the solar cell can generate electricity normally. Among them, the first protective plate can be made of one or more of polyester, nylon, PET (polyethyleneterephthalate) materials, and the thickness of the first protective plate ranges from 0.1mm to 1.5mm. The first texture layer can be made of one or more of ETFE (ethylene-tetra-fluoro-ethylene), PVDF (polyvinylidene difluoride), and PVF (polyvinyl formal). The thickness of the first texture layer ranges from 0.01mm to 0.05mm. The fifth adhesive layer is a film with adhesive properties that melts at high temperature. Specifically, it can include one or more of EVA, POE or PVB.

[0030] In some technical solutions, optionally, the first protective layer includes: a second texture layer, the surface of the second texture layer has texture, and the second texture layer is light-transmissive; or a second protective plate, the surface of the second protective plate is flat, and the second protective plate is light-transmissive.

[0031] In this technical solution, two other structures of the first protective layer are defined. In a possible technical solution, the first protective layer may only include the second texture layer. Specifically, the surface of the second texture layer has textures, and because the surface of the second texture layer with textures is arranged to face the outside, on the one hand, the rainwater can be diverted through the textures, which is conducive to the rapid discharge of rainwater out of the solar module, and on the other hand, the aesthetics of the solar module can be improved. The second texture layer can be made of one or more of ETFE, PVDF, and PVF materials, and the thickness of the second texture layer ranges from 0.01mm to 0.05mm. The second texture layer can be light-transmissive, so that light can pass through the second texture layer to the first mounting surface of the solar cell, so that the solar cell can generate electricity normally.

[0032] In another possible technical solution, the first protective plate may also include only the second protective plate, and the surface of the second protective plate is a plane. The second protective plate may be made of one or more materials selected from polyester, nylon, and PET, and the thickness of the second protective plate ranges from 0.1 mm to 1.5 mm. The second protective plate is light-transmissive, so that light can pass through the second protective plate to the first mounting surface of the solar cell, so that the solar cell can generate electricity normally.

[0033] In some technical schemes, optionally, the second protective layer includes: a third texture layer, the surface of the third texture layer has texture; a third protective plate; a sixth adhesive layer, used to bond the third texture layer and the third protective plate, and the third texture layer, the sixth adhesive layer and the third protective plate are stacked in sequence along the direction toward the solar cell.

The second protective layer includes a third texture layer, a third protective plate and a sixth adhesive layer, wherein the sixth adhesive layer is located between the third texture layer and the third protective plate, and the sixth adhesive layer is used to bond the third texture layer and the third protective plate. In the direction toward the solar cell, the third texture layer, the sixth adhesive layer and the third protective plate are stacked in sequence, that is, the third texture layer is arranged toward the outside, and the third protective plate is arranged toward the solar cell.

[0035] Furthermore, the surface of the third texture layer has texture, and because the textured surface of the third texture layer is arranged to face the outside, on the one hand, the rainwater can be diverted through the texture, which is conducive to the rapid discharge of rainwater outside the solar module, and on the other hand, the aesthetics of the solar module can be improved. The third protective plate and the third texture layer can further protect the solar cell. Among them, the third protective plate can be made of one or more of polyester, nylon, and PET materials, and the thickness of the third protective plate ranges from 0.1mm to 1.5mm. The third texture layer can be made of one or more of ETFE, PVDF, and PVF materials, and the thickness of the third texture layer ranges from 0.01mm to 0.05mm. The sixth adhesive layer is an adhesive film with adhesive properties that melts at high temperature, and can specifically include one or more of EVA, POE or PVB materials.

[0036] Furthermore, the third texture layer, the sixth adhesive layer and the third protective plate may be light-transmissive or light-opaque. In the case where the solar panel is a product for generating electricity on both sides, the third texture layer, the sixth adhesive layer and the third protective plate are light-transmissive; in the case where the solar panel is a product for generating electricity on one side, the third texture layer, the sixth adhesive layer and the third protective plate are light-opaque.

DETAILED DESCRIPTION

[0059] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0060] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0061] Refer to the following Figures 1 to 16 A solar module 100 is described according to some embodiments of the present invention.

[0062] In one embodiment according to the present application, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model proposes a solar energy component 100, including: a solar cell 110, used to convert light energy into electrical energy, the solar cell 110 has a first mounting surface 111 and a second mounting surface 112 that are opposite to each other, and the first mounting surface 111 can receive light; a first protective layer 120, located on one side of the first mounting surface 111, and the first protective layer 120 can transmit light; a second protective layer 130, located on one side of the second mounting surface 112; a support mesh 140, located between the second protective layer 130 and the solar cell 110, the support mesh 140 is used to support the solar cell 110, and the support mesh 140 has a plurality of mesh holes 142.

[0063] The solar cell assembly 100 proposed in the present application includes a solar cell 110, a first protective layer 120, a second protective layer 130 and a support net 140. The solar cell 110 can receive light energy and convert the light energy into electrical energy to realize the power generation function of the solar cell assembly 100. Specifically, the solar cell 110 has a first mounting surface 111 and a second mounting surface 112, and the first mounting surface 111 and the second mounting surface 112 are opposite to each other, wherein the first mounting surface 111 can receive light, and the solar cell 110 can convert the light energy into electrical energy after receiving the light. The first mounting surface 111 can be the front of the solar cell 110, and the second mounting surface 112 can be the back of the solar cell 110. In a possible embodiment, when the solar cell assembly 100 is installed on an object such as a building, the first mounting surface 111 of the solar cell 110 faces the outside world, and the second surface of the solar cell 110 faces the building, so that the solar cell 110 can receive light normally. In another possible embodiment, the second mounting surface 112 of the solar cell 110 can also receive light, so that the solar module 100 can generate electricity on both sides. The solar cell 110 can include any one or more of a silicon solar cell, a thin film solar cell, an organic polymer solar cell, and a nanocrystalline solar cell.

[0064] Furthermore, in order to protect the solar cell 110, the present application provides a first protective layer 120 and a second protective layer 130 on one side of the first mounting surface 111 and one side of the second mounting surface 112 of the solar cell 110, respectively. Specifically, the first protective layer 120 is located on one side of the first mounting surface 111 of the solar cell 110, and the first protective layer 120 is light-transmissive, so that light can pass through the first protective layer 120 and irradiate the first mounting surface 111, so that the solar cell 110 can receive light normally. The second protective layer 130 is located on one side of the second mounting surface 112 of the solar cell 110, and the second protective layer 130 can be light-transmissive or light-impermeable. When the second protective layer 130 is light-transmissive, both the first mounting surface 111 and the second mounting surface 112 of the solar cell 110 can receive light, and the double-sided power generation of the solar module 100 can be realized. When the second protective layer 130 is light-impermeable, only the first mounting surface 111 of the solar cell 110 can receive light, and the solar module 100 is single-sided power generation.

[0065] Furthermore, in order to improve the overall strength of the solar module 100, the present application also provides a support net 140 in the solar module 100. The support net 140 is located between the second protective layer 130 and the solar cell 110. The support net 140 can be made of metal material or other high-strength materials. The support net 140 can play a certain supporting role on both the solar cell 110 and the first protective layer 120 to improve the overall strength of the solar module 100. When the solar module 100 is impacted, the deformation of the solar cell 110 is reduced, and the damage to the solar cell 110 is reduced. The support net 140 also has a plurality of meshes 142, so that the support net 140 can be light-transmissive. When the solar module 100 is a double-sided power generation product, the second mounting surface 112 can receive light normally. In addition, by providing the support net 140 between the solar cell 110 and the second protective layer 130, the light reflection of the second protective layer 130 can be reduced, so that the colors of the front and back sides of the solar module 100 tend to be consistent.

[0066] In some embodiments, optionally, Fig. 9 , Fig.10 and Fig.15 As shown, the support mesh 140 includes: a plurality of metal wires 141, the plurality of metal wires 141 are cross-arranged to define a mesh 142, the intersection area between any two metal wires 141 defines a cross section 143, any two metal wires 141 are interconnected at the corresponding cross sections 143, and the number of cross sections 143 corresponding to any mesh 142 is greater than or equal to three.

[0067] In this embodiment, the structure of the support net 140 is further defined. The support net 140 includes a plurality of metal wires 141, and the plurality of metal wires 141 are arranged to cross each other to define meshes 142. Any two crossed metal wires 141 are connected to each other. Specifically, the intersection area between any two metal wires 141 defines a cross section 143, and any two metal wires 141 are connected to each other at the cross section 143 formed therebetween. The two metal wires 141 can be connected by welding or by winding each other.

[0068] Furthermore, the number of intersections 143 corresponding to any mesh 142 is greater than or equal to three. It can be understood that the more the number of intersections 143 corresponding to each mesh 142 is, the more balanced the force on the multiple metal wires 141 constituting the mesh 142 is, and the higher the pulling strength of the support net 140 is. In a possible embodiment, as Fig.10 As shown, the number of the cross parts 143 corresponding to any mesh 142 is four, and the four cross parts 143 are evenly distributed along the circumference of the mesh 142, so that the mesh 142 is subjected to uniform forces in the four directions of up, down, left, and right, thereby increasing the overall tensile strength of the support net 140. Among them, the metal wire 141 can be made of aluminum wire or aluminum alloy wire, or iron wire, steel wire or copper wire, etc., and the surface of the metal wire 141 can be sprayed with color. The thickness of the support net 140 ranges from 0.2mm to 1.5mm.

[0069] In some embodiments, optionally, Fig. 9 As shown, the hole area of ​​all meshes 142 in the support net 140 is P1, the coverage area of ​​all metal wires 141 in the support net 140 is P2, and P1 and P2 satisfy P1 / (P1+P2)≥0.5.

[0070] In this embodiment, the support net 140 is further defined. The hole area of ​​all meshes 142 in the support net 140 is P1, the coverage area of ​​all metal wires 141 in the support net 140 is P2, and P1 and P2 satisfy P1 / (P1+P2)≥0.5. In this way, the light-transmitting area of ​​the support net 140 can meet the use requirements, and when the first mounting surface 111 and the second mounting surface 112 of the solar cell 110 can both receive light, the second mounting surface 112 of the solar cell 110 can receive sufficient light, thereby reducing the shielding of light by the support net 140 and improving the power generation efficiency of the solar module 100.

[0071] In some embodiments, optionally, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the solar module 100 further includes: an insulating layer 150 located between the support mesh 140 and the solar cell 110 , and the insulating layer 150 can provide insulation.

[0072] In this embodiment, the solar module 100 is further defined. The solar module 100 also includes an insulating layer 150, which is made of an insulating material so that the insulating layer 150 can be insulated. The insulating layer 150 is located between the support mesh 140 and the solar cell 110. Since the support mesh 140 is made of a metal material, if the solar cell 110 is in direct contact with the support mesh 140, there is a possibility of leakage or short circuit. In order to avoid the above problems, the present application sets an insulating layer 150 between the solar cell 110 and the support mesh 140, thereby avoiding the problems of leakage and short circuit. The insulating layer 150 can be made of PET. When the solar module 100 is a single-sided power generation product, the insulating layer 150 can be opaque, and when the solar module 100 is a double-sided power generation product, the insulating layer 150 is transparent. The thickness of the insulating layer 150 ranges from 0.1mm to 0.8mm.

[0073] In some embodiments, optionally, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the solar module 100 also includes: a first adhesive layer 171, located between the first protective layer 120 and the solar cell 110, the first adhesive layer 171 is used to bond the first protective layer 120 and the solar cell 110, and the first adhesive layer 171 is light-transmissive; a second adhesive layer 172, located between the solar cell 110 and the insulating layer 150, the second adhesive layer 172 is used to bond the solar cell 110 and the insulating layer 150; a third adhesive layer 173, located between the insulating layer 150 and the supporting mesh 140, the third adhesive layer 173 is used to bond the supporting mesh 140 and the insulating layer 150; a fourth adhesive layer 174, located between the supporting mesh 140 and the second protective layer 130, the fourth adhesive layer 174 is used to bond the supporting mesh 140 and the second protective layer 130.

[0074] In this embodiment, the solar module 100 is further defined. In order to enable the first protective layer 120, the solar cell 110, the insulating layer 150, the support net 140 and the second protective layer 130 to be connected in sequence to form a whole, the present application also provides a plurality of adhesive layers in the solar module 100. Specifically, a first adhesive layer 171 is provided between the first protective layer 120 and the solar cell 110, and the first adhesive layer 171 is used to bond the first protective layer 120 and the solar cell 110. Further, the first adhesive layer 171 is light-transmissive, so that light can pass through the first adhesive layer 171 to the first mounting surface 111, so that the solar cell 110 can receive light normally. A second adhesive layer 172 is provided between the solar cell 110 and the insulating layer 150, and the second adhesive layer 172 is used to bond the solar cell 110 and the insulating layer 150. A third adhesive layer 173 is provided between the insulating layer 150 and the supporting net 140, and the third adhesive layer 173 is used to bond the insulating layer 150 to the supporting net 140. A fourth adhesive layer 174 is provided between the supporting net 140 and the second protective layer 130, and the fourth adhesive layer 174 is used to bond the supporting net 140 to the second protective layer 130. By providing the first adhesive layer 171, the second adhesive layer 172, the third adhesive layer 173 and the fourth adhesive layer 174 in the solar module 100, the first protective layer 120, the solar cell 110, the insulating layer 150, the supporting net 140 and the second protective layer 130 can be sequentially connected to form a whole.

[0075] In a possible embodiment, the first adhesive layer 171 , the second adhesive layer 172 , the third adhesive layer 173 and the fourth adhesive layer 174 are adhesive films that have adhesive properties when melted at high temperatures, and may specifically include one or more of EVA, POE or PVB materials.

[0076] In some embodiments, optionally, Figure 8 As shown, the thickness of the support mesh 140 is H1, the thickness of the third adhesive layer 173 is H2, the thickness of the fourth adhesive layer 174 is H3, and H1, H2 and H3 satisfy H1≤H2+H3.

[0077] In this embodiment, the thickness relationship between the support mesh 140, the third adhesive layer 173 and the fourth adhesive layer 174 is defined. Specifically, the thickness of the support mesh 140 is H1, the thickness of the third adhesive layer 173 is H2, and the thickness of the fourth adhesive layer 174 is H3, and H1, H2 and H3 satisfy H1≤H2+H3. It can be understood that the third adhesive layer 173 is used to bond the support mesh 140 and the insulating layer 150, and the fourth adhesive layer 174 is used to bond the support mesh 140 and the second protective layer 130. If the thickness of the third adhesive layer 173 and the fourth adhesive layer 174 is too thin, it will cause the support mesh 140 to be loosely bonded to the insulating layer 150 and the second protective layer 130. By limiting the sum of the thickness of the third adhesive layer 173 and the thickness of the fourth adhesive layer 174 to be greater than or equal to the thickness of the support mesh 140 , it is possible to ensure that the third adhesive layer 173 and the fourth adhesive layer 174 can firmly bond the support mesh 140 to the insulating layer 150 and the second protective layer 130 .

[0078] In some embodiments, optionally, Figure 3 , Figure 4 and Figure 5 As shown, the solar module 100 also includes: a support frame 160, located between the first protective layer 120 and the insulating layer 150, the support frame 160 has a receiving groove 161, the solar cell 110 is located in the receiving groove 161, the first adhesive layer 171 is also used to bond the support frame 160 to the first protective layer 120, and the second adhesive layer 172 is also used to bond the support frame 160 to the insulating layer 150.

[0079] In this embodiment, the structure of the solar module 100 is further defined. The solar module 100 may further include a support frame 160, which is used to improve the overall strength of the solar module 100. Specifically, the support frame 160 is located between the first protective layer 120 and the insulating layer 150, and the support frame 160 has a receiving groove 161. The solar cell 110 is located in the receiving groove 161, and the support frame 160 surrounds the circumference of the solar cell 110, so that the solar cell 110 can be protected by the support frame 160. The support frame 160 is bonded to the first protective layer 120 through the first adhesive layer 171, and is bonded to the insulating layer 150 through the second adhesive layer 172. The support frame 160 can be made of one or more materials selected from glass fiber board, epoxy resin, polyurethane, synthetic resin, metal or carbon fiber board.

[0080] By providing the support frame 160 in the solar module 100 , on the one hand, the overall strength of the solar module 100 can be improved, and on the other hand, a certain protection effect can be provided to the solar cell 110 .

[0081] In some embodiments, optionally, Figure 6and Figure 7 As shown, the edge of the support frame 160 protrudes from the edge of the support net 140 , or the edge of the support frame 160 is flush with the edge of the support net 140 .

[0082] In this embodiment, the positional relationship between the support frame 160 and the support net 140 is defined. Specifically, the edge of the support frame 160 protrudes from the edge of the support net 140, or the edge of the support frame 160 is flush with the edge of the support net 140. It is understandable that if the support net 140 protrudes from the edge of the support frame 160, on the one hand, it will make it difficult to trim the edges when cutting the solar module 100, and on the other hand, it will cause sharp protrusions on the edge of the solar module 100, which is easy to cause safety accidents. In order to avoid the above problems, the present application sets the edge of the support frame 160 to protrude from the edge of the support net 140, or makes the edge of the support frame 160 flush with the edge of the support net 140, so as to avoid the support net 140 protruding from the edge of the support frame 160, so as to facilitate the trimming of the solar module 100, and avoid the solar module 100 from having protruding sharp points, thereby improving the safety of the product.

[0083] like Figure 6 As shown, the support frame 160 has a length of L1 and a width of W1, the support net 140 has a length of L2 and a width of W2, L1≥L2, W1≥W2.

[0084] In some embodiments, optionally, Fig.13 As shown, the first protective layer 120 includes: a first texture layer 121, the surface of the first texture layer 121 has texture; a first protective plate 122; a fifth adhesive layer 123, used to bond the first texture layer 121 and the first protective plate 122, along the direction toward the solar cell 110, the first texture layer 121, the fifth adhesive layer 123 and the first protective plate 122 are stacked in sequence, and the first texture layer 121, the first protective plate 122 and the fifth adhesive layer 123 are light-transmissive.

[0085] In this embodiment, a structure of the first protective layer 120 is defined. The first protective layer 120 includes a first texture layer 121, a first protective plate 122 and a fifth adhesive layer 123, wherein the fifth adhesive layer 123 is located between the first texture layer 121 and the first protective plate 122, and the fifth adhesive layer 123 is used to bond the first texture layer 121 and the first protective plate 122. In the direction toward the solar cell 110, the first texture layer 121, the fifth adhesive layer 123 and the first protective plate 122 are stacked in sequence, that is, the first texture layer 121 is arranged toward the outside, and the first protective plate 122 is arranged toward the solar cell 110.

[0086] Furthermore, the surface of the first texture layer 121 has textures, and because the surface of the first texture layer 121 with textures is arranged toward the outside, on the one hand, rainwater can be diverted through the textures, which is conducive to the rapid discharge of rainwater to the outside of the solar module 100, and on the other hand, the aesthetics of the solar module 100 can be improved. The first protective plate 122 and the first texture layer 121 can further protect the solar cell 110. The first texture layer 121, the first protective plate 122 and the fifth adhesive layer 123 are all light-transmissive, so that light can pass through the first texture layer 121, the first protective plate 122 and the fifth adhesive layer 123 to the first mounting surface 111 of the solar cell 110, so that the solar cell 110 can generate electricity normally. Among them, the first protective plate 122 can be made of one or more materials selected from polyester, nylon, and PET, and the thickness of the first protective plate 122 ranges from 0.1 mm to 1.5 mm. The first texture layer 121 can be made of one or more materials such as ETFE, PVDF, and PVF. The thickness of the first texture layer 121 ranges from 0.01 mm to 0.05 mm. The fifth adhesive layer 123 is a film that has adhesive properties when melted at high temperature. Specifically, it can include one or more materials such as EVA, POE, or PVB.

[0087] In some embodiments, optionally, Fig.11 and Fig.12 As shown, the first protective layer 120 includes: a second texture layer 124, the surface of the second texture layer 124 has textures and is light-transmissive; or a second protective plate 125, the surface of the second protective plate 125 is flat and is light-transmissive.

[0088] In this embodiment, two other structures of the first protective layer 120 are defined. In a possible embodiment, as Fig.12 As shown, the first protective layer 120 may only include the second texture layer 124. Specifically, the surface of the second texture layer 124 has textures, and because the surface of the second texture layer 124 with textures is arranged toward the outside, on the one hand, the rainwater can be diverted through the textures, which is conducive to the rapid discharge of rainwater to the outside of the solar module 100, and on the other hand, the aesthetics of the solar module 100 can be improved. The second texture layer 124 can be made of one or more of ETFE, PVDF, and PVF materials, and the thickness of the second texture layer 124 ranges from 0.01 mm to 0.05 mm. The second texture layer can be light-transmissive, so that light can pass through the second texture layer 124 to the first mounting surface 111 of the solar cell 110, so that the solar cell 110 can generate electricity normally.

[0089] In another possible embodiment, Fig.11As shown, the first protective plate 122 may also include only the second protective plate 125, and the surface of the second protective plate 125 is a plane. The second protective plate 125 may be made of one or more materials selected from polyester, nylon, and PET, and the thickness of the second protective plate 125 ranges from 0.1 mm to 1.5 mm. The second protective plate 125 is light-transmissive, so that light can pass through the second protective plate 125 to the first mounting surface 111 of the solar cell 110, so that the solar cell 110 can generate electricity normally.

[0090] In some embodiments, optionally, Figure 4 As shown, the second protective layer 130 includes: a third texture layer 131, the surface of the third texture layer 131 has texture; a third protective plate 132; a sixth adhesive layer 133, used to bond the third texture layer 131 and the third protective plate 132, along the direction toward the solar cell 110, the third texture layer 131, the sixth adhesive layer 133 and the third protective plate 132 are stacked in sequence.

[0091] In this embodiment, the structure of the second protective layer 130 is defined. The second protective layer 130 includes a third texture layer 131, a third protective plate 132 and a sixth adhesive layer 133, wherein the sixth adhesive layer 133 is located between the third texture layer 131 and the third protective plate 132, and the sixth adhesive layer 133 is used to bond the third texture layer 131 and the third protective plate 132. In the direction toward the solar cell 110, the third texture layer 131, the sixth adhesive layer 133 and the third protective plate 132 are stacked in sequence, that is, the third texture layer 131 is arranged toward the outside, and the third protective plate 132 is arranged toward the solar cell 110.

[0092] Furthermore, the surface of the third texture layer 131 has textures, and because the surface of the third texture layer 131 with textures is arranged toward the outside, on the one hand, the rainwater can be diverted through the textures, which is conducive to the rapid discharge of rainwater to the outside of the solar module 100, and on the other hand, the aesthetics of the solar module 100 can be improved. The third protective plate 132 and the third texture layer 131 can further protect the solar cell 110. Among them, the third protective plate 132 can be made of one or more materials selected from polyester, nylon, and PET, and the thickness of the third protective plate 132 ranges from 0.1 mm to 1.5 mm. The third texture layer 131 can be made of one or more materials selected from ETFE, PVDF, and PVF, and the thickness of the third texture layer 131 ranges from 0.01 mm to 0.05 mm. The sixth adhesive layer 133 is an adhesive film having adhesive properties by melting at high temperature, and can specifically include one or more materials selected from EVA, POE, or PVB.

[0093] Furthermore, the third texture layer 131, the sixth adhesive layer 133 and the third protective plate 132 may be light-transmissive or light-opaque. When the solar module 100 is a product for generating electricity on both sides, the third texture layer 131, the sixth adhesive layer 133 and the third protective plate 132 are light-transmissive; when the solar module 100 is a product for generating electricity on one side, the third texture layer 131, the sixth adhesive layer 133 and the third protective plate 132 are light-opaque.

[0094] In some embodiments, optionally, the second mounting surface 112 can receive light and the second protective layer 130 can transmit light.

[0095] In this embodiment, the second protective layer 130 is further defined. When the second mounting surface 112 can receive light, the solar module 100 is a double-sided power generation product, and the second protective layer 130 is made of a light-transmitting material so that light can pass through the second protective layer 130 to the second mounting surface 112, so that both the front and back sides of the solar cell 110 can receive light, thereby realizing double-sided power generation of the solar module 100.

[0096] In a possible embodiment, the solar module 100 includes a power generation layer (i.e., solar cell 110), and a layer of metal mesh (i.e., support mesh 140) is disposed on the back of the power generation layer (i.e., the second mounting surface 112). The metal mesh is a mesh structure with high light transmittance formed by horizontally and vertically interweaving metal materials. It has metal hardness and is far lower than the thermal deformation temperature of the material according to the maximum outdoor temperature of about 100°C, and will not affect the strength of the material. The metal mesh is fixed to the frame layer (i.e., support frame 160) by adhesive, so that the thermal strength of the entire surface is improved, and the installation and fixing of the structural parts on the outer surface of the product finally solves the problem of thermal deformation of the product caused by high temperature when the product is used outdoors. Since the metal mesh is made of metal, an insulating layer 150 is disposed between the metal mesh and the power generation layer to ensure that there will be no short circuit inside the product.

[0097] The process for making the solar module 100 is as follows (eg Fig.16 shown):

[0098] S1: Select a flat carrier and place the selected pockmarked cloth on the carrier;

[0099] S2: Laying out the various components included in the solar module in sequence according to the structure;

[0100] S3: placing the carrier with various components in a closed chamber of a laminator;

[0101] S4: According to the structure, select parameters for high temperature and high pressure processing and molding;

[0102] S5: Wait for the product to cool down to 20℃ to 30℃, and trim and shape it according to the drawing.

[0103] like Fig.14 As shown, first, a flat carrier 230 is selected, and the selected hemp-dot cloth 220 is placed on the carrier 230, and then laid in sequence according to the structure. When laying, the metal mesh is laid in the center with the power generation layer as the center, and the length of the frame layer is L1, the width is W1, the length of the metal mesh is L2, the width is W2, L2≤L1, W2≤W1, to ensure that the metal mesh does not exceed the frame layer, to prevent the product from being unable to trim when cutting and trimming, or leaking out of the product to cause sharp points and cause safety accidents. To ensure the reliability of bonding, the thickness of the metal mesh H1≤the thickness H2 of the third adhesive layer 173+the thickness H3 of the fourth adhesive layer 174, to ensure that there is no lack of glue. Then, a laminator 200 is used to laminate the various components placed on the carrier 230, and the carrier 230 with various components laid is placed in the closed chamber 210 of the laminator. Afterwards, according to the structure of the solar module 100, the parameters are selected for high temperature and high pressure processing and molding, and the parameter range is shown in Table 1. After that, cool and trim the product. After the product cools down to 20℃ to 30℃, trim the product according to the drawing.

[0104] Table 1

[0105]

[0106] In another possible embodiment, the solar module 100 includes: a light-transmitting protective layer (i.e., a first protective layer 120), a power generation layer (i.e., a solar cell 110), an insulating layer 150, a mesh support layer (i.e., a support mesh 140), and a back protective layer (i.e., a second protective layer 130). Each layer is bonded to form a whole by adhesive films (a first adhesive layer 171, a second adhesive layer 172, a third adhesive layer 173, and a fourth adhesive layer 174). There are three types of light-transmitting protective layers:

[0107] 1. A light-transmitting protective layer of a planar structure (i.e., the second protective plate 125);

[0108] 2. A light-transmitting protective layer having different concave and convex textures (i.e., the second texture layer 124);

[0109] 3. A light-transmitting protective layer composed of a texture layer (ie, the first texture layer 121), an adhesive layer (ie, the fifth adhesive layer 123) and a rigid layer (ie, the first protective plate 122).

[0110] The manufacturing process of the solar module 100 is as follows:

[0111] The mesh support layer is a thin metal material that is interwoven horizontally and vertically to form a mesh structure. The interweaving points (i.e., the intersection 143) can be wound or welded to ensure that each interweaving point can effectively form a ring grid (i.e., the mesh 142). The ring grid is formed by at least three interweaving points, that is, the number of interweaving points corresponding to the ring grid is ≥3, and the number can be four. Fig.10 As shown, the four interlaced points can make the grid (i.e., mesh 142) bear the same force in the four directions of up, down, left, and right, thereby increasing the overall tensile strength. In order to make both sides of the solar module 100 transparent and generate electricity, the mesh support layer can be made of aluminum or aluminum alloy, or one or more metals selected from iron, steel, and copper, which are resistant to high density. Fig.15 As shown, the length of the mesh is M2, the width is N2, the distance of the metal wires constituting the mesh along the length direction is M1, and the distance of the metal wires constituting the mesh along the width direction is N1, N1>N2, M1>M2.

The terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense.
