CsSbSe2

CsSbSe₂ is a ternary halide perovskite semiconductor compound composed of cesium, antimony, and selenium. This material belongs to the emerging class of lead-free perovskite semiconductors currently under investigation for optoelectronic applications, as it offers potential advantages in stability and toxicity reduction compared to conventional lead-based perovskites. While still largely in the research phase, CsSbSe₂ is being explored for photovoltaic and photodetection applications where its direct bandgap and tunable electronic properties could address the performance-to-safety tradeoff in next-generation solar cells and imaging devices.
