An efficiency of flexible perovskite solar cells (Pvs-SCs) of 16.09% has been 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.
