Abstract

Abstract : In article number 2100555, Mansoo Choi, Yun Seog Lee, and co‐workers systematically investigate the self‐doping effect on the light stability of perovskite solar cells (PSCs). Although both PSCs with Pb‐rich and Pb‐deficient conditions exhibit similar initial performance, the Pb‐rich PSC degrades relatively quickly under light illumination even without H2 O and O2 . The perovskite crystal structure in the foreground represents void, interstitial, and deep‐level anti‐site defects formed during photo‐aging of unbalanced stoichiometry, even under inert ambient conditions.
