· CsBiSe2

CsBiSe₂ is a ternary semiconductor compound composed of cesium, bismuth, and selenium, belonging to the class of halide perovskite and bismuth chalcogenide material families. This is primarily a research compound under investigation for optoelectronic and photovoltaic applications, valued for its potential low toxicity compared to lead-based semiconductors and its tunable bandgap for light absorption and emission. The material is of particular interest in the photovoltaic research community as a candidate for next-generation solar cells and as a lead-free alternative in semiconductor device development.
