· ZnCu2GeSe4

ZnCu2GeSe4 is a quaternary chalcogenide semiconductor compound belonging to the family of I-III-IV-VI materials, which are of significant interest for optoelectronic and thermoelectric applications. This material is primarily investigated in research contexts for photovoltaic devices, particularly as an absorber layer in thin-film solar cells, and for thermoelectric energy conversion systems where it can potentially offer improved efficiency over binary or ternary alternatives. The quaternary composition allows tuning of the bandgap and lattice parameters compared to simpler chalcogenides, making it attractive for engineers designing next-generation photovoltaic architectures or waste-heat recovery systems, though it remains largely experimental rather than commercially established.
