Abstract
UV–O<sub>3</sub> treated annealing-free cerium oxide (CeO<sub>x</sub>) is used as the electron transport layers of flexible planar perovskite solar cells to achieve the highest PCE of 14.63%. The devices retained <italic>ca.</italic> 90% efficiency of the initial value after recovery from 500 bending cycles at <italic>r</italic> = 15 mm.
