It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0052] The photovoltaic panel of the present application is based on a perovskite solar cell. Before entering the wiring mounting equipment, the perovskite liquid has been set in the photovoltaic panel, which is believed to generate current. The perovskite solar cell is a solar cell that uses perovskite type organic metal halide semiconductor as light absorbing material, which belongs to the third generation solar cell, also known as new concept solar cell.

[0053] When receiving solar irradiation, the perovskite layer first absorbs photons to generate electron-hole pairs. Due to the difference in the excitation binding energy of the perovskite material, these carriers become free carriers or form excitons. Moreover, because these perovskite materials often have low carrier recombination probability and high carrier mobility, the diffusion distance and lifetime of the carriers are long. For specific perovskite cell power generation principle, refer to the prior art. Perovskite material needs to be concentrated: because perovskite belongs to ionic crystal material, it is more fragile and less stable than crystalline silicon, has the disadvantages of easy oxidation and poor high temperature resistance.

[0054] Overall, the present application includes the device. After the perovskite layer inside the photovoltaic glass panel is processed by the previous process, the internal perovskite layer can generate current by light. Then, after the installation and welding of the wiring, the glue coating, lamination and heating, the wiring bending, the installation and welding of the junction box, the glue injection and the frame assembly, the photovoltaic glass panel processing is completed.
