· NaInSe2

NaInSe₂ is a ternary semiconductor compound composed of sodium, indium, and selenium, belonging to the family of chalcogenide semiconductors with layered crystal structures. This material is primarily of research and development interest for optoelectronic and photovoltaic applications, where its tunable bandgap and ionic-electronic hybrid conductivity make it promising for next-generation solar cells, photodetectors, and light-emitting devices. While not yet commercialized at scale, NaInSe₂ represents an emerging alternative to conventional II-VI semiconductors, offering potential advantages in flexibility, non-toxicity, and cost-effectiveness compared to cadmium-based or lead halide perovskite systems.
