· Na2ZnSn2S6

Na2ZnSn2S6 is a quaternary sulfide semiconductor compound combining sodium, zinc, and tin in a sulfide matrix, belonging to the family of multinary chalcogenide semiconductors. This is primarily a research-phase material investigated for photovoltaic and optoelectronic applications, where its tunable bandgap and earth-abundant constituent elements (tin and zinc) offer potential advantages over conventional semiconductors like CdTe or CIGS in cost and toxicity. The material's appeal lies in its use of non-toxic, relatively abundant elements compared to traditional thin-film photovoltaics, though it remains under development and has not achieved widespread industrial 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.
