Abstract

Abstract : An efficiency of flexible perovskite solar cells (Pvs‐SCs) of 16.09% is achieved, the highest value reported for flexible Pvs‐SCs to date. The outstanding performance is attributed to the superior features of alternative electron‐transport materials, such as antireflection, a suitable work function, high electron mobility, and a reduced trap‐state density of the perovskite material.
