Cs₂SnF₆ is an inorganic fluoride ceramic compound belonging to the perovskite-related halide family, composed of cesium, tin, and fluorine. This material is primarily of research interest for optoelectronic and photovoltaic applications, particularly as a lead-free alternative in halide perovskite systems where tin-based compounds offer improved environmental and toxicity profiles compared to lead analogues. While not yet mature for high-volume engineering deployment, Cs₂SnF₆ and related tin fluorides are being investigated for potential use in solar cells, light-emitting devices, and radiation detection, where the combination of crystalline stability and bandgap tunability presents advantages over conventional semiconductors.
