KCu2GeS4
metal· JVASP-100479· KCu2GeS4
KCu2GeS4 is a ternary chalcogenide compound combining potassium, copper, germanium, and sulfur—a class of materials studied for semiconductor and photovoltaic applications. This is primarily a research compound rather than a production material, investigated for its potential in thin-film solar cells, photodetectors, and other optoelectronic devices where the bandgap and crystal structure of sulfide semiconductors offer advantages over conventional alternatives.
