Description and Uses

Copper(II) sulfide is used in antifouling paints, mixed catalysts and to develop aniline black dyes in textile printing. Further, it is used as a varnish pigment and an oxidizing agent. In addition, it is used as a component of solid state electrodes and thin-film solar cell with cadmium sulfide. It is a moderate conductor of electricity and used in photovoltaics.
