AgAlSe2
semiconductor· AgAlSe2
AgAlSe2 is a ternary compound semiconductor belonging to the I–III–VI2 family, combining silver, aluminum, and selenium in a chalcopyrite crystal structure. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its direct bandgap and strong light absorption make it potentially valuable for solar cells, photodetectors, and nonlinear optical devices. While not yet commercialized at scale, AgAlSe2 represents a promising alternative to more established semiconductors like CdTe or CIGS for applications requiring high efficiency and tunable electronic properties in thin-film device geometries.
