The material exists as the sulfosalt mineral antimonselite, which crystallizes in an orthorhombic space group.〔Jambor, J. L.; Grew, E. S."New Mineral Names" American Mineralogist, Volume 79, pages 387-391, 1994.〕 In this compound, antimony is assigned 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.〔Caracas, R.; Gonze, X. "First-principles study of the electronic properties of A2B3 minerals,, with A=Bi,Sb and B=S,Se, Note: Hypothetical sulphosalt structure derived from density functional theory"" Physics and Chemistry of Minerals 2005, volume 32 p.295-300.〕 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Antimony triselenide」の詳細全文を読む スポンサード リンク
