· Cs2Hg(ICl)2

Cs₂Hg(ICl)₂ is a mixed-halide compound semiconductor composed of cesium, mercury, iodine, and chlorine. This is a research-stage material in the halide perovskite family, being investigated for optoelectronic and photovoltaic applications where tunable bandgap and compositional flexibility are valuable. While not yet deployed in commercial products, materials in this class are of significant interest for next-generation solar cells, X-ray detectors, and light-emitting devices because halide mixing allows bandgap engineering and improved stability compared to single-halide analogs.
