· CuGa1.6In0.4S3.5

CuGa1.6In0.4S3.5 is a quaternary semiconductor compound belonging to the I-III-VI family of chalcogenides, combining copper with gallium, indium, and sulfur in a carefully tuned stoichiometry. This is primarily a research and development material rather than an established commercial product, investigated for photovoltaic and optoelectronic applications where tunable bandgap and direct band structure are advantageous. The mixed gallium-indium composition allows bandgap engineering for light absorption in solar cells and photodetectors, offering a potential alternative to binary or ternary semiconductors when specific optical or electrical properties are required for next-generation thin-film 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.
