Antimony triselenide is the chemical compound with the formula Sb
2Se
3. The material exists as the sulfosalt mineral antimonselite (IMA symbol: Atm^[2]), which crystallizes in an orthorhombic space group.^[3] In this compound, antimony has a formal oxidation state +3 and selenium −2. The bonding in this compound has covalent character as evidenced by the black color and semiconducting properties of this and related materials.^[4] The low-frequency dielectric constant (ε₀) has been measured to be 133 along the c axis of the crystal at room temperature, which is unusually large.^[5] Its band gap is 1.18 eV at room temperature.^[6]

The compound may be formed by the reaction of antimony with selenium and has a melting point of 885 K.^[4]

Applications

Sb
2Se
3 is now being actively explored for application thin-film solar cells.^[7] A record light-to-electricity conversion efficiency of 9.2% has been reported.^[8]
