Description
Summary:The design of electron transport layers (ETLs) is crucial to the performance of optoelectronic devices. A composite ETL was constructed to overcome the poor carrier extraction issue in perovskite solar cells, resulting in a maximum PCE of 19.14% with reduced hysteresis. A similar enhancement phenomenon was observed in both devices based on TiO 2 and SnO 2 ETLs. A composite ETL was constructed to improve carrier extraction in perovskite solar cells, resulting in a PCE of 19.14%.
