In article number 1605988 , Chul‐Ho Lee, Min Jae Ko, and co‐workers report the structural engineering of formamidinium lead iodide (FAPbI 3 ) perovskite thin films by partially substituting the formamidinium cations with smaller rubidium (Rb) cations. Even traces of Rb significantly enhance photovoltaic performances and long‐term stability of perovskite solar cells. This is due to the supplement favoring complete conversion of the perovskite to its photoactive phase while offering structural stabilization.
