Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to a curved photovoltaic tile. Background Art

[0002] The current curved photovoltaic tiles usually use PET and other materials as the backboard to support the entire curved photovoltaic tile, which leads to poor support effect and relatively low stability. In addition, the insulation effect of the current photovoltaic tiles is poor, which is prone to leakage. Utility Model Content

[0003] A first aspect of the utility model is to provide a curved photovoltaic tile.

[0004] The curved photovoltaic tile provided by the utility model comprises: a light-transmitting panel; a photovoltaic cell layer located on one side of the light-transmitting panel; an insulating layer located on a side of the photovoltaic cell layer away from the light-transmitting panel; and a metal back plate arranged on a side of the insulating layer away from the photovoltaic cell layer.

[0005] The curved photovoltaic tile of the utility model adjusts the conventional flexible backplane to a metal backplane, which can further improve the support strength of the photovoltaic tile. In addition, an insulating layer is provided between the metal backplane and the photovoltaic cell layer, which can prevent leakage and increase power generation. Furthermore, since the utility model adjusts the backplane to a metal backplane, a basis for backplane installation is provided. It is understandable that the current installation method can only be installed through a rigid panel and cannot be adjusted according to actual needs. After the utility model is adjusted to a metal backplane, since a basis for backplane installation is provided, a backplane can be selected to install the curved photovoltaic tile according to needs.

[0006] In some technical solutions, optionally, a mounting structure is provided on the metal back plate, and the mounting structure is used to fix the curved photovoltaic tile on the mounted body.

[0007] In this technical solution, the curved photovoltaic tiles are fixed by providing a mounting structure on the metal backplane, which is more convenient to install than the conventional technology of fixing the curved photovoltaic tiles by panels or frame installation. In addition, the metal backplane is more stable than the conventional flexible backplane. Optionally, the metal backplane is an aluminum backplane, which has the advantages of light weight and high corrosion resistance.

[0008] In some technical solutions, optionally, the metal back plate includes a protrusion, the protrusion is arranged to protrude from the photovoltaic cell layer, and the mounting structure is arranged on the protrusion.

[0009] In this technical solution, the mounting structure is arranged on the protruding part, making the installation more convenient. In addition, since the length of the metal back plate is greater than the length of the photovoltaic cell layer, the overall center of gravity of the curved photovoltaic tile can be biased toward the metal back plate, further improving the overall stability of the curved photovoltaic tile.

[0010] In some technical solutions, optionally, the mounting structure includes a mounting hole.

[0011] In this technical solution, the mounting structure includes a mounting hole, the number of which is at least 1. Of course, the mounting structure may also be a bolt, a rivet or a buckle as required. Optionally, the mounting structure is integrally formed with the metal back plate, which can improve the preparation efficiency.

[0012] In some technical solutions, optionally, the curved photovoltaic tile further includes a visible fiberglass cloth layer, and the visible fiberglass cloth layer is located between the light-transmitting panel and the photovoltaic cell layer.

[0013] In this technical solution, the photovoltaic tile of the utility model is provided with a visible fiberglass cloth layer above the photovoltaic cell layer, which can ensure the overall strength of the photovoltaic tile, provide good protection for the photovoltaic cell layer in a hail environment, and reduce the strength requirement for the light-transmitting panel, thereby making the material selection range of the light-transmitting panel wider, instead of having to use a rigid light-transmitting panel as in the prior art, which reduces the overall quality.

[0014] In some technical solutions, optionally, in the visible glass fiber cloth layer, the mass percentage of the glass fibers in the visible glass fiber cloth layer is greater than or equal to 25% and less than or equal to 35%.

[0015] In this technical solution, the glass fiber content is controlled to ensure that the curved photovoltaic tile has a certain strength and avoid damage to the photovoltaic cell layer. Under the condition of ensuring strength, it can also avoid excessive glass fiber content causing excessive overall mass. Optionally, the mass of the glass fiber accounts for 30% of the mass percentage of the visible glass fiber cloth layer.

[0016] In some technical solutions, optionally, the curved photovoltaic tile also includes a first adhesive layer, which is arranged between the visible glass fiber cloth layer and the light-transmitting panel; the material of the first adhesive layer includes at least one of ethylene-vinyl acetate copolymer, polyolefin elastomer, polyvinyl butyral and 2,4,6-trimethylbenzoyl-diphenylphosphine oxide.

[0017] In this technical solution, a first adhesive layer is provided between the visible glass fiber cloth layer and the light-transmitting panel, and the material of the first adhesive layer is limited, thereby improving the connection strength between the visible glass fiber cloth layer and the light-transmitting panel and ensuring a good light-transmitting effect.

[0018] In some technical solutions, optionally, the light-transmitting panel includes a PET (polyethylene glycolterephthalate) light-transmitting panel or a PET composite light-transmitting panel.

[0019] In this technical solution, since a visible glass fiber cloth layer is provided, the light-transmitting panel can be set as a PET light-transmitting panel or a PET composite light-transmitting panel, which ensures the strength while greatly reducing the overall quality, and does not need to be set as a rigid light-transmitting panel as in the prior art. In addition, the PET light-transmitting panel or the PET composite light-transmitting panel has a better light-transmitting effect than the rigid light-transmitting panel.

[0020] In some technical solutions, optionally, the curved photovoltaic tile further includes: a second adhesive layer, disposed between the photovoltaic cell layer and the insulating layer; and a third adhesive layer, disposed between the metal back plate and the insulating layer.

[0021] In this technical solution, the curved photovoltaic tile also includes a second adhesive layer and a third adhesive layer. The second adhesive layer is arranged between the photovoltaic cell layer and the insulating layer to achieve bonding between the photovoltaic cell layer and the insulating layer. The third adhesive layer is arranged between the metal backplane and the insulating layer to achieve bonding between the metal backplane and the insulating layer. By arranging the second adhesive layer and the third adhesive layer, the connection reliability of the photovoltaic cell layer, the insulating layer and the metal backplane is improved.

[0022] In some technical solutions, optionally, the material of the insulating layer includes PET, EPE (Expandable Polyethylene, polyethylene foam) or a composite material of PET and EPE.

[0023] In this technical solution, PET, EPE or a composite material of PET and EPE has a good insulation effect, further improving the power generation.

[0024] In some technical solutions, optionally, the material of the second adhesive layer includes at least one of ethylene-vinyl acetate copolymer, polyolefin elastomer, polyvinyl butyral and 2,4,6-trimethylbenzoyl-diphenylphosphine oxide. The material of the third adhesive layer includes at least one of ethylene-vinyl acetate copolymer, polyolefin elastomer, polyvinyl butyral and 2,4,6-trimethylbenzoyl-diphenylphosphine oxide.

[0025] In this technical solution, by selecting the materials of the second adhesive layer and the third adhesive layer, the second adhesive layer and the third adhesive layer have both good light transmission effect and can achieve reliable bonding.

[0026] In some technical solutions, optionally, the curved photovoltaic tile includes a curved structure, and the radius of the curved structure is greater than or equal to 26 mm and less than or equal to 200 mm.

[0027] In this technical solution, if the arc radius is too large, the wave crest position will be too flat, which is not conducive to the dispersion of light. If the arc radius is too small, it will not be conducive to the manufacture of curved photovoltaic tiles. Therefore, setting the radius of the curved structure between 26mm and 200mm can ensure the dispersion effect of light and facilitate the manufacture of curved photovoltaic tiles. For example, the radius of the curved structure is 40mm, 80mm or 120mm.

[0028] In some technical solutions, optionally, the curved surface structure includes wave peaks, and the number of the wave peaks is greater than or equal to 1 and less than or equal to 10.

[0029] In this technical solution, the curved surface structure is a concave-convex structure including crests and troughs. Too many crests will result in a too small radius at the crests of the curved surface structure, which is not conducive to manufacturing. Therefore, the number of crests is set between 1 and 10 to facilitate the manufacturing of curved photovoltaic tiles. For example, the number of crests is 4, 6 or 8.

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.

[0044] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the present invention. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the embodiments of the present invention is not limited to the specific embodiments disclosed below.

[0045] like Figure 1 As shown, the curved photovoltaic tile 110 provided in this embodiment includes: a light-transmitting panel 1101; a photovoltaic cell layer 1104, located on one side of the light-transmitting panel 1101; an insulating layer 1106, located on the side of the photovoltaic cell layer 1104 away from the light-transmitting panel 1101; and a metal backplane 1108, arranged on the side of the insulating layer 1106 away from the photovoltaic cell layer 1104.

[0046] The curved photovoltaic tile 110 of the present invention adjusts the conventional flexible backplane to a metal backplane 1108, which can further improve the support strength of the curved photovoltaic tile 110. In addition, an insulating layer 1106 is provided between the metal backplane 1108 and the photovoltaic cell layer 1104, which can prevent leakage and increase power generation. Furthermore, since the present invention adjusts the backplane to a metal backplane 1108, a basis for backplane installation is provided. It is understandable that the current installation method can only be installed through a rigid panel and cannot be adjusted according to actual needs. After the present invention is adjusted to a metal backplane 1108, since a basis for backplane installation is provided, a backplane can be selected to install the curved photovoltaic tile 110 according to needs.

[0047] In some embodiments, optionally, Figure 3 As shown, a mounting structure 1109 is provided on the metal back plate 1108, and the mounting structure 1109 is used to fix the curved photovoltaic tile 110 on the mounted object.

[0048] In this embodiment, the curved photovoltaic tile 110 is fixed by providing a mounting structure 1109 on the metal back plate 1108. Compared with the conventional technology of fixing the curved photovoltaic tile 110 by a panel or installing the frame, the installation is more convenient. In addition, the metal back plate 1108 is more stable than the conventional flexible back plate. Optionally, the metal back plate 1108 is an aluminum back plate, which has the advantages of light weight and high corrosion resistance.

[0049] In some embodiments, optionally, Figure 3 As shown, the metal back plate 1108 includes a protrusion 11082 , the protrusion 11082 is arranged to protrude from the photovoltaic cell layer 1104 , and the mounting structure 1109 is arranged on the protrusion 11082 .

[0050] In this embodiment, the mounting structure 1109 is arranged on the protrusion 11082, so that the installation is more convenient. In addition, since the length of the metal back plate 1108 is greater than the length of the photovoltaic cell layer 1104, the overall center of gravity of the curved photovoltaic tile 110 can be biased toward the metal back plate 1108, further improving the overall stability of the curved photovoltaic tile 110.

[0051] In some embodiments, optionally, Figure 4 and Figure 5 As shown, mounting structure 1109 includes mounting hole 11092 .

[0052] In this embodiment, the mounting structure 1109 includes a mounting hole 11092, the number of which is at least 1. Of course, the mounting structure 1109 may also be a bolt, a rivet or a buckle as required. Optionally, the mounting structure 1109 and the metal back plate 1108 are integrally formed, which can improve the manufacturing efficiency.

[0053] In some technical solutions, optionally, as Figure 2 As shown, the curved photovoltaic tile 110 further includes a visible fiberglass cloth layer 1103 , and the visible fiberglass cloth layer 1103 is located between the light-transmitting panel 1101 and the photovoltaic cell layer 1104 .

[0054] In this technical solution, the curved photovoltaic tile 110 of the utility model is provided with a visible fiberglass cloth layer 1103 above the photovoltaic cell layer 1104, so as to ensure the overall strength of the curved photovoltaic tile 110, to achieve good protection for the photovoltaic cell layer 1104 in a hail environment, and to reduce the strength requirement for the light-transmitting panel 1101, thereby making the material selection range of the light-transmitting panel 1101 wider, without having to use a rigid light-transmitting panel as in the prior art, thereby reducing the overall quality.

[0055] In some embodiments, optionally, in the visible glass fiber cloth layer 1103 , the mass percentage of the glass fibers in the visible glass fiber cloth layer 1103 is greater than or equal to 25% and less than or equal to 35%.

[0056] In this embodiment, the glass fiber content is controlled to ensure that the curved photovoltaic tile 110 has a certain strength and avoid damage to the photovoltaic cell layer 1104. Under the condition of ensuring strength, it can also avoid excessive glass fiber content leading to excessive overall mass. Optionally, the mass of the glass fiber accounts for 30% of the mass percentage of the visible glass fiber cloth layer 1103.

[0057] In some embodiments, optionally, the curved photovoltaic tile 110 further includes: a first adhesive layer 1102, disposed between the visible glass fiber cloth layer 1103 and the light-transmitting panel 1101; the material of the first adhesive layer 1102 includes at least one of ethylene-vinyl acetate copolymer, polyolefin elastomer, polyvinyl butyral and 2,4,6-trimethylbenzoyl-diphenylphosphine oxide.

[0058] In this embodiment, a first adhesive layer 1102 is provided between the visible glass fiber cloth layer 1103 and the light-transmitting panel 1101, and the material of the first adhesive layer 1102 is limited, thereby improving the connection strength between the visible glass fiber cloth layer 1103 and the light-transmitting panel 1101 and ensuring a good light-transmitting effect.

[0059] In some embodiments, optionally, Fig. 9 As shown, the light-transmitting panel 1101 includes a PET light-transmitting panel 11011 or a PET composite light-transmitting panel 11012 .

[0060] In this embodiment, due to the provision of the visible glass fiber cloth layer 1103, the light-transmitting panel 1101 can be set as a PET light-transmitting panel 11011 or a PET composite light-transmitting panel 11012, which ensures the strength while greatly reducing the overall quality, without the need to provide a rigid light-transmitting panel as in the prior art. In addition, the PET light-transmitting panel 11011 or the PET composite light-transmitting panel 11012 has a better light-transmitting effect than the rigid light-transmitting panel.

[0061] In some embodiments, optionally, Figure 2 As shown, the curved photovoltaic tile 110 also includes a second adhesive layer 1105 disposed between the photovoltaic cell layer 1104 and the insulating layer 1106 ; and a third adhesive layer 1107 disposed between the metal back plate 1108 and the insulating layer 1106 .

[0062] In this embodiment, the curved photovoltaic tile 110 also includes a second adhesive layer 1105 and a third adhesive layer 1107. The second adhesive layer 1105 is arranged between the photovoltaic cell layer 1104 and the insulating layer 1106 to achieve bonding between the photovoltaic cell layer 1104 and the insulating layer 1106. The third adhesive layer 1107 is arranged between the metal backplane 1108 and the insulating layer 1106 to achieve bonding between the metal backplane 1108 and the insulating layer 1106. By arranging the second adhesive layer 1105 and the third adhesive layer 1107, the connection reliability of the photovoltaic cell layer 1104, the insulating layer 1106 and the metal backplane 1108 is improved.

[0063] In some embodiments, optionally, the material of the insulating layer 1106 includes PET, EPE, or a composite material of PET and EPE.

[0064] In this embodiment, PET, EPE or a composite material of PET and EPE has a good insulation effect, further improving the power generation.

[0065] In some embodiments, optionally, the material of the second adhesive layer 1105 includes at least one of ethylene-vinyl acetate copolymer, polyolefin elastomer, polyvinyl butyral and 2,4,6-trimethylbenzoyl-diphenylphosphine oxide. The material of the third adhesive layer 1107 includes at least one of ethylene-vinyl acetate copolymer, polyolefin elastomer, polyvinyl butyral and 2,4,6-trimethylbenzoyl-diphenylphosphine oxide.

[0066] In this embodiment, by selecting the materials of the second adhesive layer 1105 and the third adhesive layer 1107 , the second adhesive layer 1105 and the third adhesive layer 1107 have both good light transmission effect and can achieve reliable bonding.

[0067] In some embodiments, optionally, the curved photovoltaic tile 110 includes a curved structure 1110, and the radius of the curved structure 1110 is greater than or equal to 26 mm and less than or equal to 200 mm.

[0068] In this embodiment, the curved photovoltaic tile 110 with a multi-segment curved surface structure 1110 is more conducive to the divergence of light and has better lighting. In addition, if the arc radius is too large, the position of the wave crest 11101 will be too flat, which is not conducive to the dispersion of light. If the arc radius is too small, it will be not conducive to the manufacture of the curved photovoltaic tile 110. Therefore, setting the radius of the curved surface structure 1110 between 26mm and 200mm can not only ensure the dispersion effect of light, but also facilitate the manufacture of the curved photovoltaic tile 110. For example, the radius of the curved surface structure 1110 is 40mm, 80mm or 120mm.

[0069] In some embodiments, optionally, the curved surface structure 1110 includes peaks 11101 , and the number of the peaks 11101 is greater than or equal to 1 and less than or equal to 10.

[0070] In this embodiment, too many peaks 11101 will result in too small a radius at the peaks 11101 of the curved structure 1110, which is not conducive to manufacturing. Therefore, the number of peaks 11101 is set between 1 and 10 to facilitate the manufacturing of the curved photovoltaic tile 110. For example, the number of peaks 11101 is 4, 6 or 8.

[0071] Another embodiment of the utility model provides a lightweight curved photovoltaic tile 110 that is light, has good mechanical properties, is easy to install, and is low-cost. The main purpose is to solve the problem that most existing curved photovoltaic tile 110 components rely on punching holes or frames on rigid panels for installation. The transparent rigid panel is used as the front panel, which makes the overall weight of the component too heavy and cannot meet the requirements of lightweight installation. Although the simple lightweight curved photovoltaic tile 110 is installed using a frame, it can improve the strength of the component to a certain extent, but in severe conditions such as hail, the protection of the battery cells is minimal.

[0072] The lightweight curved photovoltaic tile 110 provided in this embodiment is as follows: Figure 2 As shown, it consists of a light-transmitting panel 1101, a first adhesive layer 1102, a visible glass fiber cloth layer 1103, a photovoltaic cell layer 1104, a second adhesive layer 1105, an insulating layer 1106, a third adhesive layer 1107, and a metal backplane 1108. The light-transmitting panel 1101 is also called a photovoltaic front panel, which is composed of transparent polymer materials, and commonly used ones include PET and its composite materials. For example, there is a polymer material layer on the outside of the front panel, which is transparent PET with properties such as waterproof, weather resistance, etc.

[0073] The first adhesive layer 1102 is one of ethylene-vinyl acetate copolymer (EVA), polyolefin elastomer (POE), polyvinyl butyral (PVB) and 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO), such as polyolefin elastomer (POE), and has a thickness of 0.3 mm-0.7 mm.

[0074] The visible glass fiber cloth layer 1103 is also called a high-transmittance glass fiber cloth layer, which is a high-transmittance glass fiber prepreg, which refers to a resin matrix & reinforcement material combination made by fully impregnating glass fibers with a resin matrix under certain conditions and then hot-pressing. The resin matrix is, for example, an epoxy resin material, and the glass fibers are continuous glass fiber mesh cloths, such as satin spun glass fiber cloth, plain glass fiber cloth or twill glass fiber cloth, such as satin spun glass fiber cloth. The glass fiber content in the composite material is 30%, ensuring good mechanical support performance. For example, a high-transmittance glass fiber cloth material with an adhesive film.

[0075] Photovoltaic cell layer 1104, for example, a cell with an unobstructed front side, such as an XBC cell (a new type of high-efficiency cell derived from an IBC cell structure, an IBC cell being a crystalline silicon photovoltaic cell with full back electrode contact).

[0076] The second adhesive layer 1105 is one of ethylene-vinyl acetate copolymer (EVA), polyolefin elastomer (POE), polyvinyl butyral (PVB) and 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO), such as polyolefin elastomer (POE), and has a thickness of 0.3 mm-0.7 mm.

[0077] The material of the insulating layer 1106 is PET, EPE, fiber composite material, etc., for example, PET material with excellent insulation properties.

[0078] The third adhesive layer 1107 is one of ethylene-vinyl acetate copolymer (EVA), polyolefin elastomer (POE), polyvinyl butyral (PVB) and 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO), such as polyolefin elastomer (POE), and has a thickness of 0.3 mm-0.7 mm.

[0079] The metal back plate 1108 is also called a shaped metal plate. Figure 3 and Figure 4 As shown, for example, black, anodized aluminum plates, with a thickness of 0.5mm-3mm, shaped metal plates with a size greater than 100mm-700mm, and with mounting holes, the minimum number is 1.

[0080] The curved photovoltaic tile assembly of this embodiment is a curved surface, the radius of the curved surface is 26mm to 100mm, and the number of curved surfaces is 1 to 10. The process is a one-step method or a two-step method. The one-step method is to shape the metal plate as a curved surface, and then perform lamination and other processes after the materials are attached; the two-step method is to shape the metal plate as a flat surface, and first perform the lamination process and then perform assembly plasticization. Both methods can achieve the effect of a curved surface.

[0081] The lightweight curved photovoltaic tile provided in this embodiment is light in weight and easy to carry, which can effectively reduce transportation and packaging costs. It has good mechanical properties and can reduce the damage to the battery cells caused by severe impacts such as hail, thereby ensuring power generation efficiency and extending the service life of the components. The components themselves are equipped with installation holes, which are user-friendly and can be installed quickly.

[0082] like Figure 6 As shown, an embodiment of the second aspect of the utility model provides a roof 11, and the roof 11 provided in this embodiment includes the curved photovoltaic tile 110 of any embodiment of the first aspect of the utility model.

[0083] The third aspect of the utility model provides a building 1, such as Figure 7 As shown, the building 1 provided in this embodiment includes the curved photovoltaic tile 110 of any embodiment of the first aspect of the utility model, or as Figure 8 As shown, the building 1 includes a roof 11 according to an embodiment of the second aspect of the utility model.
