We developed perovskite solar cells (PSCs) with a ZnO electron-transporting layer (ETL) of which the surface was passivated with methoxybenzoic acid self-assembled monolayers (SAMs). The self-assembled monolayer (SAM) simultaneously improved the photovoltaic performance and device stability. First,...
