· JVASP-155375· CuGeSe2

CuGeSe2 is a ternary semiconductor compound composed of copper, germanium, and selenium, belonging to the I-III-VI₂ chalcogenide family. This material is primarily investigated in photovoltaic and thermoelectric research contexts, where its semiconductor properties and bandgap characteristics make it a candidate for thin-film solar cells and energy conversion devices. While not yet widely commercialized compared to established alternatives like CdTe or CIGS, CuGeSe2 attracts research interest due to its tunable optoelectronic properties and potential for cost-effective renewable energy applications.
