The perovskite solar cell is a solar cell using perovskite type organic metal halide semiconductor as light absorbing material, which belongs to the third generation solar cell and is also called new concept solar cell.

[0106] When receiving solar irradiation, the perovskite layer first absorbs photons to generate electron-hole pairs. Due to the difference in the exciton 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.

[0107] Then, these unrecombined electrons and holes are collected by the electron transport layer and hole transport layer, respectively. Electrons are transported from the perovskite layer to the isoelectronic transport layer and finally collected by the FTO; holes are transported from the perovskite layer to the hole transport layer and finally collected by the metal electrode. Of course, these processes inevitably involve some carrier loss, such as reversible recombination of electrons in the electron transport layer with holes in the perovskite layer, recombination of electrons in the electron transport layer with holes in the hole transport layer (in cases where the perovskite layer is not dense), and recombination of electrons in the perovskite layer with holes in the hole transport layer. To improve the overall performance of the battery, these carrier losses should be minimized. Finally, a photocurrent is generated by connecting the FTO and the metal electrode.

The automated processing technology for photovoltaic panels according to claim 1, characterized in that: In step 6, the photovoltaic panel enters the junction box installation equipment, passes through obstructions and is fixed, the junction box is placed and solder paste is applied; In the first step, the photovoltaic panel enters the fixed platform and is fixed by the universal positioning structure. Then, the pallet-grabbing gripper of the dual-end three-axis robot moves to take out the pallet from the storage and place it on the buffer platform. The box-grabbing end of the dual-end three-axis robot takes out the junction box on the pallet and places it at the glue application position in step 5. The paste-applying end of the dual-end three-axis robot applies solder paste to the junction box.

7. The automated processing technology for photovoltaic panels according to claim 1, characterized in that: In step 7, the photovoltaic panel enters the junction box welding equipment, passes through obstructions, and is fixed and welded; Blocking, fixing, and welding: The photovoltaic panel enters the conveyor line inside the junction box welding equipment and is fixed by the universal positioning structure of the conveyor line; the vision module of the three-axis coordinate platform detects the photovoltaic panel, and the junction box welding end of the three-axis coordinate platform descends to weld the junction box and the cable.

8. A glass coating equipment, characterized in that: The glass coating equipment blocks and fixes the photovoltaic glass panel, and performs light irradiation and current detection on the welding process. It includes a second frame, a dual three-coordinate robot, a light detection platform, and a recovery branch line; the second frame is provided in two sets, and a conveyor line is installed between the two sets of the second frame. The light detection platform is installed at the lower end of the conveyor line, and a universal positioning structure is installed on the outside of the conveyor line. The illumination detection platform includes a bottom light source and a current measuring component. The bottom light source is adapted to illuminate a photovoltaic panel with a conveyor line installed at the bottom. The current measuring component includes fixed plates located on both sides of the conveyor line. A lifting cylinder is installed on the side of the fixed plate facing away from the conveyor line. The output end of the lifting cylinder is adapted to extend and retract vertically and is equipped with an upper clamping plate. A lower clamping plate is installed on the side of the fixed plate opposite to the conveyor line. The upper and lower clamping plates are adapted to clamp onto the end of the photovoltaic panel's wiring. The glass coating equipment also includes a lifting and reversing platform, which is installed between the recycling branch line and the light detection platform; The lifting and reversing platform includes a conveyor line, a positioning limit switch, a side positioning mechanism, a lifting mechanism, and a side pushing mechanism. Two sets of positioning limit switches and side positioning mechanisms are installed. The positioning limit switch is adapted to detect the passage of the photovoltaic panel and control the side positioning mechanism. The side positioning mechanism is adapted to block the photovoltaic panel. The output end of the lifting mechanism is adapted to drive the conveyor line to move up and down. The side pushing mechanism is adapted to push the photovoltaic panel. When the lifting mechanism is not working, the height of the recovery branch line is lower than the height of the conveyor line.
