· K2VAgS4

K2VAgS4 is a mixed-metal chalcogenide semiconductor compound containing potassium, vanadium, silver, and sulfur. This is an experimental research material rather than an established industrial compound; materials in this chemical family are investigated for potential applications in photovoltaics, photoelectrochemistry, and solid-state electronics where layered sulfide structures can enable tunable band gaps and ion transport properties.
