· In2Cu1S3.5

In2Cu1S3.5 is a quaternary semiconductor compound combining indium, copper, and sulfur in a specific stoichiometric ratio, belonging to the family of copper-indium sulfide (CIS) and related chalcogenide semiconductors. This material is primarily of research interest for photovoltaic and optoelectronic applications, particularly as a potential absorber layer or component in thin-film solar cells and photodetectors where its bandgap and optical properties could offer advantages in light absorption and carrier transport. Relative to conventional CIS or CIGS (copper-indium-gallium-selenide) absorbers, quaternary formulations like this are explored to fine-tune electronic structure and improve efficiency or reduce material costs, though industrial deployment remains limited and material is not yet widely commercialized.

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.
