Abstract

Abstract : A low‐temperature, solution‐processable organic electron‐transporting material (ETM) is successfully developed for efficient conventional n‐i‐p perovskite solar cells (PVSCs). This ETM can show a high efficiency over 17% on rigid device and 14.2% on flexible PVSC. To the best of our knowledge, this efficiency is among the highest values reported for flexible n‐i‐p PVSCs with negligible hysteresis thus far.
