Enhanced Crystallinity of Triple-Cation Perovskite Film via Doping NH4SCN

Abstract The trap-state density in perovskite films largely determines the photovoltaic performance of perovskite solar cells (PSCs). Increasing the crystal grain size in perovskite films is an effective method to reduce the trap-state density. Here, we have added NH4SCN into perovskite precursor so...
