· Zn1 Cu2 Sn1 Se4

Zn₁Cu₂Sn₁Se₄ is a quaternary semiconductor compound belonging to the chalcogenide family, specifically a variant of the kesterite structure class used in photovoltaic research. This material is primarily investigated for thin-film solar cell applications as an earth-abundant alternative to conventional silicon and CIGS (copper indium gallium selenide) technologies, offering potential cost and supply-chain advantages due to its use of common elements (zinc, copper, tin, and selenium). Engineers consider this compound for next-generation photovoltaic devices where material abundance, toxicity reduction, and scalable manufacturing are design drivers.
