LEAD HALIDE RECOVERY METHOD FOR PEROVSKITE SOLAR CELL, AND A LEAD HALIDE UTILIZATION METHOD
The present invention relates to a lead halide recovery method for a perovskite solar cell, and a lead halide utilization method. The lead halide recovery method comprises: putting a perovskite solar cell to be recovered into a heating device for high-temperature heating, so as to remove a low-boiling-point material in the perovskite solar cell, and remain a high-boiling-point material; soaking the remained high-boiling-point material in a solvent, and filtering to obtain a lead-containing solution; and adding a complexing agent to the lead-containing solution for complexation reaction, and filtering and drying to obtain a highly pure lead-containing coordination complex. The recovered lead-containing coordination complex is dissolved to prepare a coating solution; then a prepared perovskite absorption layer is coated with the coating solution and then drying is performed to obtain a lead coordination complex passivation layer; and a second transmission layer and a back electrode are sequentially prepared on the lead coordination complex passivation layer until the manufacturing process of the perovskite solar cell is completed. The present invention is simple in process, and can recycle a lead-containing component in a waste perovskite solar cell material, and can also improve the performance of a newly manufactured perovskite solar cell.
