US 2013/0280855 A1 · METHOD FOR PRODUCING COMPOUND HAVING CHALCOPYRITE STRUCTURE

Abstract

To obtain high-quality chalcopyrite particles having a small particle size using a relatively inexpensive raw material in a simple and easy process in which complicated equipment (such as vacuum equipment) is not necessary. Provided is a method for producing a compound having a chalcopyrite structure represented by a compositional formula: ABC2, the method including: a step of dissolving a Group 11 element A, a Group 13 element B, and a Group 16 element C of the periodic table in a solvent to prepare a solution; and a step of contacting the solution with a reducing agent.
