semiconductor· Zn1 Cu2 Sn1 S4
Zn₁Cu₂Sn₁S₄ is a quaternary sulfide semiconductor compound belonging to the family of earth-abundant chalcogenides, structurally related to kesterite and stannite phases. This material is primarily investigated in photovoltaic research as a potential absorber layer for thin-film solar cells, valued for its elemental composition using relatively abundant, non-toxic constituents (zinc, copper, tin, and sulfur) as an alternative to cadmium telluride or CIGS absorbers. While largely in the research and development phase rather than widespread commercial production, this compound class has garnered attention because it could enable more cost-effective and environmentally sustainable solar technologies.
