Abstract

Abstract In this work, a SnO 2 /ZnO bilayered electron transporting layer (ETL) aimed to achieve low energy loss and large open‐circuit voltage ( V oc ) for high‐efficiency all‐inorganic CsPbI 2 Br perovskite solar cells (PVSCs) is introduced. The high‐quality CsPbI 2 Br film with regular crystal gr...
