The material exists as the sulfosalt mineral antimonselite, which crystallizes in an orthorhombic space group.[2] In this compound, antimony has the oxidation state +3 and selenium −2, but in fact the bonding in this compound is highly covalent as reflected by the black color and semiconducting properties of this and related materials.[3] It may be formed by the reaction of antimony with selenium. ApplicationsSb2Se3 is now actively explored for thin film solar cells and have achieved 6.5% certified efficiency.
