· Cu0.7In1.3Se2.3

Cu0.7In1.3Se2.3 is a copper indium selenide-based quaternary semiconductor compound, part of the chalcopyrite family of materials used in photovoltaic and optoelectronic applications. This composition represents a tuned variant of the CuInSe2 system, where stoichiometric adjustments are made to optimize bandgap energy and electronic properties for specific device requirements. The material is primarily investigated in research and development contexts for thin-film solar cells and photodetectors, where lattice tuning and composition engineering offer pathways to improve efficiency and wavelength selectivity compared to binary or ternary semiconductors.

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.
