Roles of fullerene‐based interlayers in enhancing the performance of organometal perovskite thin‐film solar cells are elucidated. By studying various fullerenes, a clear correlation between the electron mobility of fullerenes and the resulting performance of derived devices is determined. The metallic characteristics of the bilayer perovskite/fullerene field‐effect transistor indicates an effective charge redistribution occurring at the corresponding interface. A conventional perovskite thin‐film solar cell derived from the C 60 electron‐transporting layer (ETL) affords a high power conversion efficiency of 15.4%.
