CuFeSe2
semiconductor· CuFeSe2
CuFeSe₂ is a ternary chalcogenide semiconductor compound combining copper, iron, and selenium in a fixed stoichiometric ratio. This material belongs to the family of earth-abundant semiconductor absorbers and is primarily studied for photovoltaic and thermoelectric applications as a lower-cost, less-toxic alternative to cadmium telluride and other rare-element semiconductors. CuFeSe₂ remains largely in the research and development phase, with interest driven by its direct bandgap suitable for light absorption and the abundance of its constituent elements, though commercial deployment faces challenges related to phase stability and defect management compared to established thin-film solar technologies.
