<p>A chalcopyrite-type compound, for instance, CuInS2 or CuGaS2, is prepared by subjecting a Group I - III oxide composition, containing at least one of the Group Ib element, for instance copper (Cu), and at least one of the Group IIIb element, for instance indium (In) or gallium (Ga) to a heat treatment under a reducing atmosphere containing the Group VIb element, for instance sulfur (S) or selenium (Se), or under an atmosphere containing a reducing compound of the Group VIb element, thereby converting said oxide composition into a chalcopyrite-type compound. <IMAGE> <IMAGE></p> |
