· Cs2NbCuSe4

Cs2NbCuSe4 is a quaternary chalcogenide semiconductor compound composed of cesium, niobium, copper, and selenium. This material belongs to the family of complex metal selenides and is primarily of research interest rather than established industrial production, being investigated for photovoltaic and thermoelectric energy conversion applications. The layered structure and tunable band gap characteristic of ternary and quaternary chalcogenides position this compound as a candidate for next-generation solar cells and solid-state energy harvesting devices where conventional silicon or cadmium telluride may be limited.
