How It Compares
Within the halide perovskite photovoltaics class.
Unlike the widely recognized halide perovskites such as CsPbBr3 or CsSnI3, which typically feature simpler cubic or orthorhombic frameworks, Ge2K2La2Se8 represents a more intricate structural class. While members like CsPbBr3 are foundational to standard solar cell architectures, Ge2K2La2Se8 offers a distinct chemical composition that challenges conventional perovskite design rules, providing a unique platform for studying stability in non-halide, complex semiconducting lattices.
