Abstract

A copper antimony iodide rudorffite, Cu3SbI6, was first prepared by using a low-temperature solution-processing approach. Its film absorbs 320–520 nm light and has an indirect bandgap of 2.43 eV. Solar cells with a structure of ITO/PEDOT:PSS/Cu3SbI6/PC61BM/Al were made, giving a power conversion efficiency of 0.50% and a fill factor of 67.09%.
