Abstract

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 C60 electron-transporting layer (ETL) affords a high power conversion efficiency of 15.4%.
