Achieving efficiency above 30% with new inorganic cubic perovskites X₂SnBr₆ (X = Cs, Rb, K, Na) via DFT and SCAPS-1D

Abstract

The solar sector is increasingly focusing on inorganic cubic halide perovskite materials without lead (Pb) because of their exceptional structural, electronic, and optoelectronic properties. At the first phase, we thoroughly...
