· JVASP-35214· Na2ZnSe2

Sodium zinc selenide (Na2ZnSe2) is an inorganic ceramic compound belonging to the chalcogenide family, characterized by ionic bonding between alkali metal, transition metal, and selenide anions. This material is primarily investigated in research contexts for optoelectronic and photovoltaic applications, where its semiconducting properties and tunable bandgap make it relevant for next-generation solar cells, photodetectors, and light-emitting devices. Na2ZnSe2 represents an alternative to more common II-VI semiconductors, offering potential advantages in cost-effectiveness and compositional flexibility, though it remains largely experimental compared to established materials like CdTe or CdSe used in commercial thin-film technologies.
