Perovskite Solar Cells In article number 2000149 , Jun Song, Qing Shen, and co‐workers establish a new strategy to improve the performance of perovskite solar cells, which sheds more light on the currently proposed mechanism governing the action of moisture on the quality of perovskite film. Self‐passivated perovskite solar cells show an extraordinary V OC of 1.17 V and highest efficiency of 21.38 %.
