Cu₃AsS₄ is a quaternary semiconductor compound belonging to the chalcogenide family, combining copper with arsenic and sulfur in a crystalline structure. This material is primarily of research interest for photovoltaic and thermoelectric applications, where its semiconducting properties and elemental composition offer potential advantages in solar cell development and waste-heat recovery systems. Cu₃AsS₄ represents an underexplored alternative to more established semiconductor materials, though it remains largely in the experimental stage with limited commercial deployment compared to conventional silicon or chalcopyrite-based solar absorbers.
