· Na2 Se1

Sodium selenide (Na₂Se) is an inorganic semiconductor compound belonging to the alkali metal chalcogenide family. It is primarily of interest in research and development contexts for optoelectronic and photovoltaic applications, where its direct bandgap and ionic bonding characteristics make it a candidate material for studying semiconductor physics and exploring next-generation solar cell architectures. While not yet widely commercialized, Na₂Se and related chalcogenides are investigated as potential alternatives to more conventional semiconductors due to their tunable electronic properties and abundance of constituent elements.
