Na2 Cu2 Se2
semiconductor· Na2 Cu2 Se2
Na₂Cu₂Se₂ is a quaternary chalcogenide semiconductor composed of sodium, copper, and selenium, belonging to the family of mixed-metal selenides. This compound is primarily a research material under investigation for photovoltaic and thermoelectric applications, valued for its potential to combine copper's high electrical conductivity with selenium's semiconducting properties in a tunable bandgap structure. Engineers consider this material class for next-generation solar cells and waste-heat recovery systems where cost-effective, earth-abundant alternatives to traditional semiconductors like CdTe or CIGS are needed.
