Zn3InAgS5

Zn₃InAgS₅ is a quaternary semiconductor compound containing zinc, indium, silver, and sulfur, belonging to the family of I-III-VI₂ and related multinary chalcogenide semiconductors. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its tunable bandgap and crystal structure make it a candidate for thin-film solar cells, photodetectors, and light-emitting devices. Its combination of earth-abundant and rare elements positions it as an exploratory alternative to conventional III-V semiconductors, though it remains largely in development phase rather than established industrial production.
