First principles insight into the study of the structural, stability, and optoelectronic properties of alkali‐based single halide perovskite ZSnCl₃ (Z = Na/K) materials for photovoltaic applications

Metal halide perovskites are crystalline materials with a sharp increase in popularity and rapidly becoming a major contender for optoelectronic device applications. In this work, we provide the optoelectronic features of a possible novel candidate, ZSnCl
