· JVASP-108718· ZnCu2SnSeS3

ZnCu2SnSeS3 is a quaternary chalcogenide compound belonging to the family of copper-tin-based semiconductors with selenium and sulfur anionic components. This is an experimental/research material primarily of interest for photovoltaic and thermoelectric applications, as compounds in this family combine tunable bandgaps with moderate thermal conductivity, making them candidates for next-generation thin-film solar cells and waste-heat recovery devices. The material represents an alternative to established kesterite and related absorber layers, offering potential cost advantages through earth-abundant constituent elements compared to conventional 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.
