An electron-transporting layer (ETL) with improved charge extraction-transfer kinetics and a perovskite film with improved quality highly determine the power conversion efficiency (PCE) of perovskite solar cells (PSCs). Herein, various alkali chlorides (MCl, M = Li, Na, K, Rb and Cs) are employed as...
