· Cs2CuNbSe4

Cs2CuNbSe4 is a quaternary chalcogenide semiconductor compound composed of cesium, copper, niobium, and selenium. This material belongs to the family of complex metal selenides and is primarily investigated in research settings for optoelectronic and photovoltaic applications, where its layered crystal structure and tunable bandgap make it a candidate for next-generation solar cells and photodetectors. While not yet widely commercialized, chalcogenide semiconductors like this compound are notable for their strong light absorption, potential for low-cost manufacturing compared to conventional silicon-based devices, and suitability for thin-film device architectures.
