· Cu0.15In1.85Se2.85

Cu0.15In1.85Se2.85 is a copper-indium selenide compound semiconductor, a derivative of the CuInSe₂ (CIS) family with modified copper and indium stoichiometry. This material is primarily explored in photovoltaic research as an absorber layer in thin-film solar cells, offering potential advantages in bandgap tuning and defect tolerance compared to stoichiometric CIS. Its modified composition targets improved efficiency and stability in next-generation solar technologies, though it remains predominantly a research compound rather than a commercial-scale material.

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.
