Zn2In2S5
semiconductor· Zn2In2S5
Zn₂In₂S₅ is a ternary semiconductor compound combining zinc, indium, and sulfur—part of the I-III-VI₂ semiconductor family. This material is primarily investigated in research contexts for optoelectronic and photovoltaic applications, where its direct bandgap and tunable electronic properties make it attractive for next-generation thin-film solar cells, light-emitting devices, and photocatalytic applications. Engineers consider this compound as an alternative to traditional CdTe or CIGS absorber layers because of its lower toxicity profile and potential for lattice engineering through compositional variation.

Export Control
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.
