    • An improved process for producing a light-absorbing chalcopyrite film is disclosed, which comprises the steps of: applying at least one solution containing at least either of (a) an organic compound of a metal in Group 1B of the periodic table and (b) an organic compound of a metal in Group 3B of the periodic table on a substrate at least once to thereby form a thin film containing the organic compound (a) and the organic compound (b); heating the thin film in a reducing or inert gas atmosphere to convert the thin film into a thin metal film comprising the Group 1B metal and the Group 3B metal; and heating the thin metal film in an atmosphere containing either an element in Group 6B of the periodic table or a compound thereof to thereby convert the thin metal film into a thin chalcopyrite film. This process eliminates the problem concerning the control of the composition and thickness of a light-absorbing chalcopyrite film, and is suitable for the mass production of homogeneous large light-absorbing plates for use in solar cells.
    • 公开了一种用于制备光吸收黄铜矿膜的改进方法,其包括以下步骤:施加至少一种至少一种包含(a)元素周期表第1B族中的(a)金属有机化合物和(b) 在基板上的元素周期表3B中的金属的有机化合物至少一次,从而形成含有有机化合物(a)和有机化合物(b)的薄膜; 在还原或惰性气体气氛中加热薄膜以将薄膜转变成包含1B族金属和3B族金属的薄金属膜; 并在含有元素周期表第6B族元素或其化合物的气氛中加热薄金属膜,从而将薄金属膜转变为薄黄铜矿膜。 该方法消除了关于光吸收性黄铜矿膜的组成和厚度的控制的问题,并且适用于批量生产用于太阳能电池的均匀的大型吸光板。
