Distinguishing the migration time scale of ion species in perovskite solar cells
Chemical Physics Letters(2022)
摘要
•The migration time scales for different ions in operational perovskite devices are identified.•The cations play a decisive role in hysteresis effect rather than anions.•Steric hindrance effects play a crucial role in determine the ion migration dynamics.
