Cs2SnP2Se6
semiconductor· Cs2SnP2Se6
Cs₂SnP₂Se₆ is a quaternary semiconductor compound belonging to the halide perovskite and metal chalcogenide families, combining cesium, tin, phosphorus, and selenium in a layered or 3D crystal structure. This is primarily a research-phase material studied for its potential optoelectronic and photovoltaic properties, particularly in the context of lead-free perovskite alternatives and solid-state energy conversion devices. The tin-based composition makes it relevant to sustainable semiconductor development, where researchers investigate its stability, bandgap tunability, and suitability for next-generation photovoltaic, photodetector, and thermal-to-electric conversion applications.
