Role of spiro-OMeTAD in performance deterioration of perovskite solar cells at high temperature and reuse of the perovskite films to avoid Pb-waste

Abstract

Undertaken this study to understand the performance degradation of perovskite solar cells at high temperature and under a humid environment, and then tried to reuse the perovskite films from the degraded cells to recover the cell efficiency so as to avoid Pb-waste.
