NaInSnS4
semiconductor· NaInSnS4
NaInSnS4 is a quaternary sulfide semiconductor compound combining sodium, indium, tin, and sulfur into a direct or near-direct bandgap material. This is a research-phase compound investigated for thin-film photovoltaic and optoelectronic applications, particularly as an earth-abundant alternative to conventional cadmium telluride (CdTe) or copper indium gallium selenide (CIGS) solar cells. The material's appeal lies in its use of more abundant elements than indium selenides and potential for tunable band structure, though it remains largely in developmental stages without widespread commercial deployment.

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.
