Abstract
This application discloses a method for recovering lead iodide from a perovskite solar battery, and a recycling system. The method for recovering lead iodide from a perovskite solar battery includes the following steps: pretreating a recycled perovskite solar battery to obtain perovskite; putting the perovskite into a second solvent to dissolve lead iodide to obtain a lead iodide-containing solution; and mixing the lead iodide-containing solution with a third solvent to precipitate the lead iodide, and collecting a lead iodide precipitate. A boiling point of the third solvent is lower than a boiling point of the second solvent. The recycling system for recovering lead iodide from a perovskite solar battery includes: a recycled perovskite solar battery stripping apparatus, a lead iodide extraction apparatus, and a lead iodide precipitate separation apparatus.
