title = "Homogenous Alloys of Formamidinium Lead Triiodide and Cesium Tin Triiodide for Efficient Ideal-Bandgap Perovskite Solar Cells",
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 (03)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 %.",
