文摘

We developed a versatile and environmentally friendly solution approach for the fabrication of a variety of metal sulfide nanocrystal thin films. Metal oxides, metal hydroxides, metal chlorides, metal acetates, and metal acetylacetonates can be used as the starting materials and dissolved in thioglycolic acid and ethanolamine, forming many types of metal鈥搊rganic precursor solutions. High quality CdS, SnS, CuInS₂, CuSbS₂, Cu₂ZnSnS₄, Cu(In_0.7Ga_0.3)S₂, and luminescent Ag-doped Zn_xCd_1鈥?i>xS nanocrystal thin films have been successfully prepared by spin-coating their corresponding metal precursor solutions. Cu₂ZnSn(S,Se)₄ thin film solar cell with a power conversion efficiency of 6.83% has been realized by this versatile method.
