Abstract

The alloying behavior between FAPbI₃ and CsSnI₃ perovskites is studied carefully for the first time, which has led to the realization of single-phase hybrid perovskites of (FAPbI₃)_1−x(CsSnI₃)_x (0<x<1) compositions with anomalous bandgaps. (FAPbI₃)_1−x(CsSnI₃)_x perovskites exhibit stable, homogenous composition/microstructure at the nanoscale, as confirmed by microscopic characterization. The ideal bandgap of 1.3 eV for single-junction solar cell operation is achieved in the rationally-tailored (FAPbI₃)_0.7(CsSnI₃)_0.3-composition perovskite. Solar cells based on this new perovskite show power conversion efficiency up to 14.6 %.
