Multi-element metal chalcogenide and method for preparing the same
A multi-element metal chalcogenide and a method for preparing the same are provided. The multi-element metal chalcogenide includes multiple metal elements. A multi-element metal chalcogenide powder is prepared, and all of the multiple metal elements of the multi-element metal chalcogenide are derived from at least one of simple substance powders of the metal elements and one or more alloy powders mixed in accordance with a mole ratio. A solution phase synthesis of the powder of the multi-element metal chalcogenide is then conducted under normal pressure to prepare the multi-element metal chalcogenide. The multi-element metal chalcogenide can be coated to obtain a film or used to make a target and then bombard the target for sputtering a film. In such a way, a selenization process which is conventional in fabricating the semiconductor solar cell is eliminated, thus improving production yield and efficiency.
