semiconductor· Cu0.95In1.05Se2.05
Cu0.95In1.05Se2.05 is a narrow-bandgap semiconductor compound based on the copper indium selenide (CIS) family, with composition near the stoichiometric CuInSe2 but slightly indium-rich and selenium-rich. This material is primarily investigated for photovoltaic applications, particularly as an absorber layer in thin-film solar cells, where its tunable bandgap and strong light absorption make it an attractive alternative to cadmium telluride and silicon-based cells. The slight deviation from ideal stoichiometry is deliberately engineered to optimize defect states and carrier transport, making it particularly relevant for research into high-efficiency polycrystalline solar absorbers and tandem photovoltaic devices.

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.
