Cs3Sn3F2Cl7
semiconductor· Cs3Sn3F2Cl7
Cs3Sn3F2Cl7 is a mixed-halide perovskite-related semiconductor compound containing cesium, tin, fluorine, and chlorine. This is a research-phase material being investigated for optoelectronic and photovoltaic applications, particularly as part of the broader family of halide perovskites seeking lead-free alternatives with improved stability. The tin-based composition addresses toxicity concerns of lead perovskites while the mixed halide structure offers tunable bandgap and potential enhanced tolerance to moisture and thermal degradation compared to single-halide analogs.
