Abstract:Perovskite solar cells (PSCs) have attracted extensive attention in photovoltaic applications owing to their superior efficiency, and the buried interface plays a significant role in determining the efficiency and stability of PSCs. Herein, a plant-derived small molecule, ergothioneine (ET), is adopted to heal the defective buried interface of CsPbIBr 2 -based PSC to improve power conversion efficiency (PCE). Because of the strong interaction between Lewis base groups (−C�O and − C�S) in ET and uncoordinated P… Show more
