[0058] The present application provides a photovoltaic module, such as Figure 1 As shown, the photovoltaic component includes: a frame 100, a laminate 200 and an impact-resistant member 300, the frame 100 is used to be installed on a mounting platform 700; the laminate 200 is installed on the frame 100; the impact-resistant member 300 is installed on the frame 100, and the impact-resistant member 300 is arranged on the side of the laminate 200 away from the mounting platform 700, and the impact-resistant member 300 is injection molded by aliphatic or aromatic polycarbonate.

[0059] The above-mentioned photovoltaic module is provided with an impact-resistant part 300 and a laminate 200 on the frame 100, and the impact-resistant part 300 is arranged on the side of the laminate 200 away from the installation platform 700, that is, the impact-resistant part 300 is arranged on the side of the laminate 200 facing the light, and the impact-resistant part 300 is injection molded by aliphatic or aromatic polycarbonate, and has high structural strength and strong impact resistance. The impact-resistant part 300 serves as a protective layer of the laminate 200, thereby improving the impact resistance of the photovoltaic module.

[0060] In some embodiments, the impact-resistant member 300 and the laminate 200 are laminated. The impact-resistant member 300 and the laminate 200 are laminated and arranged so that the impact-resistant member 300 serves as a protective layer of the laminate 200.

[0061] Specifically, Figure 1 As shown, in this embodiment, the frame 100 is provided with two mounting grooves 110 arranged at intervals along the height direction of the frame 100, and the impact-resistant member 300 and the laminated member 200 are respectively installed in the corresponding mounting grooves 110. By providing two mounting grooves 110 on the frame 100, and the two mounting grooves 110 are arranged at intervals along the height direction of the frame 100, that is, the two mounting grooves 110 have a gap, so that there is a gap between the laminated member 200 and the impact-resistant member 300 installed in the two mounting grooves 110, thereby preventing the impact-resistant member 300 from squeezing the laminated member 200.

[0062] Specifically, the dimension of the impact member 300 along the height direction of the frame 100 is within the range of 2-4 mm. The dimension of the impact member 300 along the height direction of the frame 100, i.e., the thickness of the impact member 300, limits the thickness of the impact member 300, thereby limiting the impact resistance of the impact member 300.

[0063] Preferably, the dimension of the impact-resistant member 300 along the height direction of the frame 100 is 3 mm.

[0064] Specifically, the light transmittance of the impact-resistant member 300 is ≥ 91%. By limiting the light transmittance of the impact-resistant member 300 , the influence of the impact-resistant member 300 on the light absorption efficiency of the laminate 200 is reduced.

The ultra-white coated tempered glass 210 and the crystalline silicon solar cell layer 230 are connected by the first connection layer 220, and the back tempered glass 250 and the crystalline silicon solar cell layer 230 are connected by the second connection layer 240. The ultra-white coated tempered glass 210 and the back tempered glass 250 serve as protective layers for the crystalline silicon solar cell layer 230, thereby improving the impact resistance of the laminate 200. In addition, the ultra-white coated tempered glass 210 is located on a side close to the anti-impact member 300, that is, at Figure 1 The viewing angle is small, the laminate 200 is arranged below the anti-impact member 300 , and the light-facing surface of the laminate 200 faces the lower end surface of the anti-impact member 300 , which further improves the impact resistance of the laminate 200 .

[0066] Specifically, the first connection layer 220 or the second connection layer 240 is a thermoplastic or thermosetting adhesive film.

[0067] Specifically, a hydrophobic film layer is disposed on the side of the ultra-clear coated tempered glass 210 away from the first connecting layer 220. That is, the hydrophobic film layer is laid on the light-facing surface of the ultra-clear coated tempered glass 210, thereby improving the waterproof performance of the laminate 200.

[0068] Specifically, an anti-reflection and anti-reflection film layer is provided on the side of the hydrophobic film layer away from the ultra-clear coated tempered glass 210. That is, the anti-reflection and anti-reflection film layer is laid on the light-facing surface of the hydrophobic film layer, thereby reducing the reflected light on the surface of the laminate 200, thereby increasing the light transmittance of the laminate 200, reducing stray light, and improving the conversion efficiency of the laminate 200.

[0069] Specifically, a grid coating is disposed on the side of the rear tempered glass 250 that is away from the second connection layer 240. That is, a grid coating is disposed on the backlight surface of the rear tempered glass 250, thereby improving the crack resistance and durability of the laminate 200.

[0070] More specifically, the various structural components of the laminate 200 are arranged in the order of anti-reflection and anti-reflection film, hydrophobic film, ultra-clear coated tempered glass 210, first connecting layer 220, crystalline silicon solar cell layer 230, second connecting layer 240 and back tempered glass 250.
