Abstract
A tailored SnO2 layer using double electron transport layers (ETLs) was designed to overcome interfacial energy barriers enhance charge transport and decrease charge recombination at the perovskite/ETL interfaces. Through this dual interfacial engineering approach compact SnO2 layers with an ideal interfacial energy-level alignment were prepared using SnCl2 and NH4Cl salts leading to efficient charge extraction. Stable perovskite solar cells with a power conversion efficiency of 21.46% a high open-circuit voltage of 1.10 V and a fill factor of 0.79 were successfully achieved using this approach. The devices also exhibited negligible hysteresis and no significant efficiency loss after a 2400 h stability test at ambient conditions without encapsulation. These results demonstrate an efficient approach to achieving high-quality ETL layers for efficient and stable solar cells. ? 2023 The Authors. Published by American Chemical Society
