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.
