How It Compares
Within the halide perovskite photovoltaics class.
Unlike the widely studied lead-based perovskites such as CsPbBr3 and CsSnI3, K8Sn4Te12 incorporates tellurium to achieve its semiconducting properties, placing it in a distinct subgroup of chalcogenide-based materials. While many halide perovskites are prone to environmental instability, this compound benefits from its position on the convex hull, offering a more robust structural alternative to more volatile members like Cs4I12Sn4.
