TECHNICAL FIELD

[0001] The utility model relates to photovoltaic technology field, specifically, relate to a photovoltaic tile. BACKGROUND

[0002] The current curved photovoltaic tile sets silica aerogel felt on the back of the cell layer to achieve fireproofing. However, this method directly connects the cell layer with the silica aerogel felt, and the silica aerogel felt has weak impact resistance, which leads to the cell layer being easily damaged under external force. SUMMARY

[0003] The utility model aims at least solves the problem that the conventional photovoltaic tile in the prior art directly connects the cell layer with the aerogel felt, leading to the cell layer being easily damaged.

[0004] Therefore, the utility model provides a photovoltaic tile, the photovoltaic tile is a curved structure, and the photovoltaic tile comprises a light-transmitting panel, a cell layer arranged on one side of the light-transmitting panel, a reinforcing plate arranged on the side of the cell layer away from the light-transmitting panel, and an aerogel thermal insulation layer arranged on the side of the reinforcing plate away from the cell layer.

[0005] The photovoltaic tile provided in the application is a curved structure, and the photovoltaic tile with the curved structure can maximize the reception of direct sunlight and has high photoelectric conversion efficiency. The reinforcing plate arranged between the aerogel thermal insulation layer and the cell layer can improve the impact resistance of the side of the cell layer where the aerogel thermal insulation layer is located. In addition, the aerogel thermal insulation layer has better fireproofing effect than conventional fireproofing materials such as high-flame-retardant glass fiber resin plates.

[0006] In the above technical solution, the aerogel thermal insulation layer comprises one or a combination of the following: an aerogel thermal insulation blanket, an aerogel thermal insulation felt, an aerogel-glass cloth composite layer, an aerogel-PET (Polyethylene-Terephthalate) composite layer, and an aerogel-aluminum foil composite layer.

[0007] In the technical solution, the aerogel thermal insulation blanket and the aerogel thermal insulation felt are convenient to purchase and easy to prepare. The aerogel-glass cloth composite layer retains the excellent heat insulation and fireproofing performance of aerogel, significantly improves the mechanical strength and tear resistance through the reinforcement of glass cloth, and is more suitable for photovoltaic tile scenarios that need to bear loads or are easily impacted by external forces. The aerogel-PET composite layer is more suitable for the bending requirements of curved photovoltaic tiles on the basis of maintaining fireproofing performance due to the flexibility and lightweight characteristics of the PET film, and the weather resistance of PET can delay the pulverization of aerogel. The aerogel-aluminum foil composite layer significantly improves the overall fireproofing performance at high temperatures through the reflection and radiation ability of the aluminum foil and the heat resistance of aerogel, and the moisture-proof characteristics of the aluminum foil can protect the aerogel from water vapor erosion and prolong the service life.

[0008] In the above technical solution, optionally, the thickness of the aerogel insulation layer is greater than or equal to 1 mm and less than or equal to 5 mm.

[0009] In this technical solution, the aerogel insulation layer has a certain thickness, which provides better fire resistance compared to conventional aerogel insulation films that are less than 1mm thick.

[0010] In the above technical solution, the reinforcing plate may optionally include one or a combination of the following: PET plate, CPC (Continuous-fiber-reinforced-Polycarbonate) plate and fiberglass plate.

[0011] In this technical solution, the PET board, as the reinforcing plate of the photovoltaic tile, is lightweight, highly tough, and weather-resistant, effectively resisting ultraviolet aging and suitable for flexible photovoltaic modules; the CPC board has high strength, impact resistance, and dimensional stability, making it suitable for high-load or extreme climate environments; and the fiberglass board has excellent mechanical strength, high temperature resistance, and corrosion resistance, making it suitable for long-term outdoor use.

[0012] In the above technical solution, optionally, the thickness of the reinforcing plate is greater than or equal to 0.3 mm and less than or equal to 0.7 mm.

[0013] In this technical solution, the thickness of the reinforcing plate is limited to ensure a certain level of support strength and to prevent the overall thickness of the photovoltaic tile from becoming too thick.

[0014] Optionally, in the above technical solution, the photovoltaic tile further includes a first adhesive layer disposed between the reinforcing plate and the aerogel insulation layer for connecting the reinforcing plate and the aerogel insulation layer; the first adhesive layer includes one or a combination of the following: EVA (Ethylene-Vinyl-Acetate) adhesive layer, POE (Polyolefin-Elastomer) adhesive layer, EPE (Ethylene-Polyethylene-Ethylene) adhesive layer and PVB (Polyvinyl-Butyral) adhesive layer.

[0015] In this technical solution, since the aerogel insulation layer of this application has a certain thickness, the connection strength between the reinforcing plate and the aerogel insulation layer can be improved by connecting them through the first adhesive layer. Furthermore, EVA, POE, EPE, and PVB adhesive layers are all suitable encapsulation materials for photovoltaic tiles.

[0016] In the above technical solution, optionally, the thickness of the first adhesive layer is greater than or equal to 0.3 mm and less than or equal to 0.6 mm.

[0017] In the technical solution, the thickness of the first bonding layer is limited, which is beneficial to guarantee the connection strength between the reinforcing plate and the aerogel thermal insulation layer, and also does not make the overall thickness of the photovoltaic tile too large, which is in line with the lightweight development.

[0018] In the above technical solution, the photovoltaic tile further comprises: a second bonding layer arranged between the light-transmitting panel and the cell layer; and a third bonding layer arranged between the reinforcing plate and the cell layer, and the second bonding layer and the third bonding layer each comprise one or a combination of the following: an EVA glue layer, a POE glue layer, an EPE glue layer, and a PVB glue layer.

[0019] In the technical solution, the light-transmitting panel and the cell layer are bonded through the bonding layer, and the reinforcing plate and the cell layer are also bonded through the bonding layer, so that the connection strength of the entire photovoltaic tile can be guaranteed, and the service life is improved.

[0020] In the above technical solution, the light-transmitting panel comprises a tempered glass panel and / or a resin panel.

[0021] In the technical solution, when the tempered glass panel is used as the panel of the photovoltaic tile, it has high light transmittance (greater than or equal to 91%), excellent weather resistance and mechanical strength, can withstand hail impact and snow load, and has strong ultraviolet aging resistance; the resin panel is light in weight, has excellent impact resistance, and can be bent to adapt to the design of a curved surface.

[0022] In the above technical solution, the resin panel comprises a polycarbonate panel and / or a polymethyl methacrylate panel.

[0023] In the technical solution, the polycarbonate panel and / or the polymethyl methacrylate panel each has good impact resistance, and is thus suitable for use as the panel of the photovoltaic tile.

[0024] In the above technical solution, the cell layer comprises one or a combination of the following: a PERC (Passivated-Emitter-Rear-Cell) cell (passivated-emitter-rear-cell) layer, a TOPCON (Tunnel-Oxide-Passivated-Contact) cell (tunnel-oxide-passivated-contact) layer, an IBC (Interdigitated-Back-Contact) cell (interdigitated-back-contact) layer, and an HJT (Heterojunction-Technology) cell (heterojunction-technology) layer.

[0025] In the technical solution, the PERC cell layer, the TOPCON cell layer, the IBC cell layer, and the HJT cell layer each has good power generation efficiency, and is particularly suitable for power generation of the photovoltaic tile.

[0026] In the above technical solution, optionally, the radius of the curved surface structure is greater than or equal to 30mm and less than or equal to 150mm.

[0027] In this technical solution, if the radius of the arc is too large, the peak position will be too flat, which is not conducive to the dispersion of light. If the radius of the arc is too small, it will not be conducive to the manufacturing of curved photovoltaic tiles. Therefore, the radius of the curved structure is set between 30mm and 150mm, which can both ensure the dispersion effect of light and facilitate the manufacturing of curved photovoltaic tiles.

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

[0029] In this technical solution, the curved structure is a concave-convex structure including crests and troughs. Too many crests will result in the radius of the crest of the curved structure being too small, 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. Attached Figure Description

[0034] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0036] like Figure 1The utility model provides a kind of photovoltaic tile 1 of curved surface structure, photovoltaic tile 1 of curved surface structure can maximize receive solar direct light, photoelectric conversion efficiency is higher.

[0037] Photovoltaic tile 1 includes light-transmitting panel 11, cell layer 13, reinforcing plate 15 and aerogel heat insulation layer 17 connected in sequence, light-transmitting panel 11 has high light transmittance, and is located the outermost layer of photovoltaic tile 1, play anti ultraviolet, can ensure that more sunlight is effectively converted into electric energy, and then improve the power generation efficiency of entire photovoltaic tile 1 system. Cell layer 13 is located at one side of light-transmitting panel 11, converts light energy into electric energy. Reinforcing plate 15 is located at the side of cell layer 13 away from light-transmitting panel 11;Aerogel heat insulation layer 17 is located at the side of reinforcing plate 15 away from cell layer 13.

[0038] The photovoltaic tile 1 provided by the application has certain fireproof performance by setting the aerogel heat insulation layer 17, and the aerogel heat insulation layer 17 has better fireproof effect than the conventional high-flame-retardant glass fiber resin plate and other fireproof materials. In addition, the reinforcing plate 15 is arranged between the aerogel heat insulation layer 17 and the cell layer 13, so that the impact resistance of the cell layer 13 on the side of the aerogel heat insulation layer 17 is improved.

[0039] In the above technical solution, optionally, the aerogel heat insulation layer 17 includes one or a combination of the following: aerogel heat insulation blanket, aerogel heat insulation felt, aerogel-glass cloth composite layer, aerogel-PET composite layer, and aerogel-aluminum foil composite layer.

[0040] In this technical solution, the aerogel heat insulation layer 17 can be aerogel or a derivative product of aerogel, such as an aerogel-glass cloth composite layer, an aerogel-PET composite layer, and an aerogel-aluminum foil composite layer.

[0041] The aerogel heat insulation blanket and the aerogel heat insulation felt are easy to purchase and convenient to prepare. In addition, the aerogel is nanoscale, that is, the pore size of the aerogel is greater than or equal to 1 nm and less than or equal to 100 nm. The nanometer pores of the nanometer aerogel felt / blanket can block high-temperature heat radiation, and the nanometer skeleton can withstand the deformation of the component after being combined with the fiber, which improves the efficiency by more than 50% compared with traditional microporous insulation cotton (such as rock wool).

[0042] The specific surface area of the aerogel heat insulation layer 17 of the application is greater than or equal to 500 m2 / g and less than or equal to 1000 m2 / g, which greatly improves the heat insulation performance due to the ultra-high specific surface area.

[0043] The aerogel-glass cloth composite layer retains the excellent heat insulation and fireproof performance of aerogel, and significantly improves the mechanical strength and tear resistance through the reinforcement of glass cloth, making it more suitable for scenarios that need to bear load or are easily impacted by external forces; the aerogel-PET composite layer is more suitable for the bending requirement of curved photovoltaic tiles on the basis of maintaining fireproof performance due to the flexibility and lightweight characteristics of PET film, and the weather resistance of PET can delay the pulverization of aerogel; the aerogel-aluminum foil composite layer significantly improves the overall fireproof performance at high temperatures through the radiation reflection ability of aluminum foil in cooperation with the heat resistance of aerogel, and the moisture-proof property of aluminum foil can protect aerogel from water vapor erosion and prolong the service life.

[0044] In the above technical solution, the thickness of the aerogel heat insulation layer 17 is greater than or equal to 1 mm and less than or equal to 5 mm.

[0045] In this technical solution, the aerogel heat insulation layer 17 has a certain thickness, and compared with the conventional aerogel heat insulation film with a thickness of less than 1 mm, the fireproof effect is better.

[0046] In addition, some of the disclosed photovoltaic tiles in the file directly connect the aerogel heat insulation layer 17 and the battery layer 13, and protect the battery layer 13 through the aerogel heat insulation layer 17. Therefore, the thickness of the aerogel heat insulation layer 17 is usually set to be more than 10 mm, which makes the overall thickness of the photovoltaic tile 1 larger, which is not conducive to miniaturization. In the present application, the reinforcing plate 15 is added between the aerogel heat insulation layer 17 and the battery layer 13, so that the thickness of the aerogel heat insulation layer 17 does not need to be set so large, and is less than or equal to 5 mm, so that the overall volume of the photovoltaic tile 1 is smaller.

[0047] Optionally, the thickness of the gel heat insulation layer is greater than or equal to 2 mm and less than or equal to 4 mm. For example, 3 mm or 4 mm.

[0048] In the above technical solution, the reinforcing plate 15 includes one or a combination of the following: a PET (Polyethylene-Terephthalate) plate, a CPC (Continuous-fiber-reinforced-Polycarbonate) plate, and a glass fiber plate.

[0049] In this technical solution, the PET plate as the reinforcing plate 15 of the photovoltaic tile 1 has the characteristics of lightweight, high toughness and weather resistance, can effectively resist ultraviolet aging, and is suitable for flexible photovoltaic modules; the CPC plate has high strength, impact resistance and dimensional stability, and is suitable for high load or extreme climate environments; the glass fiber plate has excellent mechanical strength, high temperature resistance and corrosion resistance, and is suitable for long-term outdoor use.

[0050] The thickness of the reinforcing plate 15 can be greater than or equal to 0.3 mm and less than or equal to 0.7 mm. By limiting the thickness of the reinforcing plate 15, a certain supporting strength is ensured, and the overall thickness of the photovoltaic tile 1 can also be prevented from being too thick.

[0051] Of course, in some embodiments, the reinforcing plate 15 can be a flexible metal layer. The flexible metal layer (such as a copper foil, an aluminum foil, or a stainless steel sheet) can significantly improve the bending and tearing resistance of the battery layer 13, prevent brittle battery materials (such as a silicon wafer or a perovskite layer) from cracking in bending or vibration, and adapt to curved installation or mobile scenarios.

[0052] In the above technical solution, the photovoltaic tile 1 further includes a first adhesive layer 16 arranged between the reinforcing plate 15 and the aerogel thermal insulation layer 17, and used for connecting the reinforcing plate 15 and the aerogel thermal insulation layer 17. The first adhesive layer 16 includes one or a combination of the following: an EVA (Ethylene-Vinyl-Acetate) adhesive layer, a POE (Polyolefin-Elastomer) adhesive layer, an EPE (Ethylene-Polyethylene-Ethylene) adhesive layer, and a PVB (Polyvinyl-Butyral) adhesive layer.

[0053] In this technical solution, since the aerogel thermal insulation layer 17 has a certain thickness, the connection strength between the reinforcing plate 15 and the aerogel thermal insulation layer 17 can be improved by the first adhesive layer 16. The EVA adhesive layer, the POE adhesive layer, the EPE adhesive layer, and the PVB adhesive layer are all suitable for the packaging material of the photovoltaic tile 1.

[0054] The thickness of the first adhesive layer 16 is greater than or equal to 0.3 mm and less than or equal to 0.6 mm. By limiting the thickness of the first adhesive layer 16, the connection strength between the reinforcing plate 15 and the aerogel thermal insulation layer 17 can be ensured, and the overall thickness of the photovoltaic tile 1 can also be prevented from being too large, which is in line with the development of lightweight.

[0055] Optionally, the thickness of the first adhesive layer 16 is greater than or equal to 0.4 mm and less than or equal to 0.5 mm. For example, 0.4 mm or 0.5 mm.

[0056] In the above technical solution, the photovoltaic tile 1 further includes a second adhesive layer 12 arranged between the light-transmitting panel 11 and the battery layer 13, and a third adhesive layer 14 arranged between the reinforcing plate 15 and the battery layer 13. The second adhesive layer 12 and the third adhesive layer 14 each include one or a combination of the following: an EVA adhesive layer, a POE adhesive layer, an EPE adhesive layer, and a PVB adhesive layer.

[0057] In the technical solution, the light-transmitting panel 11 and the battery layer 13 and the reinforcing plate 15 and the battery layer 13 are bonded through the bonding layers, so that the connection strength of the entire photovoltaic tile 1 can be ensured, and the service life is improved.

[0058] It should be understood that the components of the first bonding layer 16, the second bonding layer 12, and the third bonding layer 14 can be the same. Of course, when different materials need to be connected, the components of the first bonding layer 16, the second bonding layer 12, and the third bonding layer 14 can also be different from each other.

[0059] The thickness of the second bonding layer 12 and the third bonding layer 14 can be consistent with the thickness of the first bonding layer 16, or can be inconsistent.

[0060] In the above technical solution, the light-transmitting panel 11 includes a tempered glass plate and / or a resin plate. The resin plate includes a polycarbonate plate and / or a polymethyl methacrylate plate.

[0061] In the technical solution, when the tempered glass plate is used as the panel of the photovoltaic tile 1, it has high light transmittance (greater than or equal to 91%), excellent weather resistance and mechanical strength, can withstand hail impact and snow load, and has strong ultraviolet aging resistance; the resin plate is light in weight, has excellent impact resistance, and can be bent to adapt to curved surface design.

[0062] In the above technical solution, the battery layer 13 includes one or a combination of the following: a PERC (Passivated-Emitter-Rear-Cell) battery (passivated emitter and rear cell) layer, a TOPCON (Tunnel-Oxide-Passivated-Contact) battery (tunnel-oxide-passivated-contact battery) layer, an IBC (Interdigitated-Back-Contact) battery (interdigitated-back-contact battery) layer, and an HJT (Heterojunction-Technology) battery (heterojunction-technology battery) layer.

[0063] In the technical solution, the PERC battery layer, the TOPCON battery layer, the IBC battery layer, and the HJT battery layer all have good power generation efficiency, long photoelectric conversion life, and low power decay, and are particularly suitable for power generation of the photovoltaic tile 1.

[0064] The battery layer 13 can be composed of a battery and a frame, and a certain gap is provided between the battery and the frame. In this way, when an external force is applied, the frame has a certain displacement buffer, so as to avoid damage to the battery due to scratching, but the gap should not be too large, and can be less than or equal to 5 mm.

[0065] Optionally, the radius of the curved surface structure is greater than or equal to 30 mm and less than or equal to 150 mm.

[0066] In this technical solution, if the radius of the arc is too large, the position of the wave peak 18 is too flat, which is not conducive to the dispersion of light, and if the radius of the arc is too small, it is not conducive to the manufacture of the curved photovoltaic tile 1. Therefore, the radius of the curved surface structure is set to be between 30 mm and 150 mm, which can not only ensure the dispersion effect of light, but also be conducive to the manufacture of the curved photovoltaic tile 1.

[0067] Optionally, the radius of the curved surface structure is greater than or equal to 50 mm and less than or equal to 120 mm. For example, 80 mm, 100 mm, or 120 mm.

[0068] In the above technical solution, optionally, the curved surface structure includes wave peaks 18, and the number of the wave peaks 18 is greater than or equal to 1 and less than or equal to 10.

[0069] In this technical solution, the curved surface structure is a concave-convex structure including wave peaks 18 and wave troughs. If the number of the wave peaks 18 is too large, the radius at the wave peak 18 of the curved surface structure will be too small, which is not conducive to the manufacture. Therefore, the number of the wave peaks 18 is set to be between 1 and 10, which is conducive to the manufacture of the curved photovoltaic tile 1.

[0070] Optionally, the number of the wave peaks 18 is greater than or equal to 3 and less than or equal to 8. For example, 3, 5, or 8.

[0071] Another embodiment of the present application provides a photovoltaic module. It needs to be understood that the curved photovoltaic tile provides a choice for building photovoltaic integration due to its good building adaptability and high power generation efficiency, but in the building field, it is often required to have excellent fireproof characteristics.

[0072] The aerogel series products have been widely used in the field of building fire protection, and the supplier system is mature. The product packaging scheme is diverse (back glue, combined with PET, aluminum foil, etc.), not only has CLASS A fireproof test certification, but also is relatively hydrophobic, can adapt to curved surfaces, and is easy to cut.

[0075] ​2. The encapsulation adhesive film (i.e. the second adhesive layer 12, the third adhesive layer 14 and the first adhesive layer 16 described above) is selected from one of EVA adhesive film, POE adhesive film, EPE adhesive film or PVB adhesive film, and the thickness is 0.3mm-0.6mm.
