About Antimony Selenide Sb2Se3 Powder:
Antimony triselenide is a compound with the chemical formula Sb2Se3. The substance exists in the form of the sulfide mineral antimony pyroxene and presents an orthotic space group. In this compound, the oxidation state of antimony form is +3, and that of selenium form is −2. The bonding of this compound has the properties of covalent bonds, which can be demonstrated by the blackness and the semiconductor properties of this and related materials with a low-frequency permittivity (ε0) of 133 along the C-axis at room temperature and an abnormally large bandgap of 1.18 eV at room temperature. Antimony triselenide can be formed by the reaction of antimony with selenium at a melting point of 885 K.
Antimony selenide (Sb2Se3) is a binary monophase compound with large raw material reserves, low toxicity and low price. At the same time, the bandgap is suitable (~ 1.15eV), and the light absorption coefficient is large (>;105 cm-1), the long crystal temperature is low, which is very suitable for the production of new low-cost and low toxicity thin-film solar cells, and the theoretical photoelectric conversion efficiency can reach more than 30%.

How is Antimony Selenide Sb2Se3 Powder Produced?
The invention discloses a method for preparing antimony selenide film, the method is:
(1) The antimony selenide film was prepared by RF magnetron sputtering process on the substrate of the film to be prepared: Ar gas was selected as the sputtering gas, antimony selenide ceramic target was used as the target material, the sputtering power density was set at 0.6~5W/cm2 and the sputtering pressure was set at 0.2~10Pa.
(2) Online selenium compensation is carried out during the preparation of antimony selenide thin film by sputtering. The online selenium compensation is that the solid selenium source is evaporated by the thermal evaporation process while sputtering. The selenium source is high purity selenium particles or selenium powder.
Applications of Antimony Selenide Sb2Se3 Powder:
Sb2Se3 is currently being actively explored for use in thin-film solar cells. It was reported that the conversion efficiency of light to electricity reached 9.2 percent.
Sb2se3 is mainly used in metallurgy, industry, chemical industry and other industries.
Sb2Se3 can be used in alloys as a compound or additive.
Sb2se3 can also be used as a catalyst for organic chemical reactions.
