Abstract

The present invention relates to a method which can effectively remove perovskite light absorbers, hole transport layers, metal electrodes, and the like by immersing a waste perovskite-based photoelectric conversion element module in a cleaning solution under predetermined conditions. The present invention can recover a substrate from the waste module and manufacture a photoelectric conversion element having a photoelectric conversion efficiency level comparable to the initially high level again, using the same.
