[0020] By arranging plate-type heat sinks 2 and protective plates 3 on both side surfaces of the photovoltaic cell 1, the photovoltaic cell 1 can be cooled and protected. At the same time, a fireproof plate 4 is also arranged on the outer side of the plate-type heat sink 2, so that the photovoltaic component has good fireproof performance, greatly improving the stability and service life of the photovoltaic component.

[0021] In this embodiment, preferably, the fireproof board 4 is a high-pressure decorative fire-resistant board.

[0022] Specifically, the photovoltaic cell 1 is formed by a plurality of single cell slices interconnected by interconnecting strips.

[0023] Furthermore, a fixing structure 5 is provided between the plate-type heat sink 2 , the photovoltaic cell 1 and the protection plate 3 , which can fix the three to the fireproof plate 4 .

[0024] Specifically, the fixing structure 5 includes several clamps 51 and fixing screws 52 provided on the clamps 51 and capable of being screwed and fixed to the fireproof board 4. The upper and lower ends of the plate-type heat sink 2, photovoltaic cell 1 and protective plate 3 are respectively embedded in the clamps 51.

[0025] During assembly, first, the plate heat sink 2, photovoltaic cell 1 and protective plate 3 are attached in this order, and then the two ends of the attached assembly are respectively embedded in the clamp 51 for fixation, and finally the fixing screws 52 are screwed on the fireproof board 4 to complete the assembly. It is practical and convenient, and the installation process can adopt a simple pasting installation process, which is simple and fast, avoiding the complicated installation process of conventional roof photovoltaic panels, and also saving roof space.
