· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
