Antimony triselenide is the chemical compound with the formula Sb2Se3. The material exists as the sulfosalt mineral antimonselite, which crystallizes in an orthorhombic space group. 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.
It may be formed by the reaction of antimony with selenium.
Applications
Sb2Se3 is now actively explored for thin film solar cells and have achieved 5.6% certified efficiency.
