CuGeS2
metal· JVASP-155374· CuGeS2
CuGeS₂ is a ternary chalcogenide compound combining copper, germanium, and sulfur, belonging to the family of metal sulfides investigated for semiconductor and optoelectronic applications. This material is primarily of research interest rather than established industrial production, with potential applications in photovoltaic devices, thermoelectric systems, and infrared optics where its electronic band structure and light-absorption properties are exploited. Engineers would consider this compound when designing next-generation thin-film solar cells or thermal energy conversion systems where earth-abundant alternatives to cadmium telluride or lead halide perovskites are needed.

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.
