Abstract
A method of preparing a Ag2ZnSn(S,Se)4 compound, including dissolving selenourea (SeC(NH2)2) in an aprotic solvent, and dissolving a silver salt, a zinc salt, and a tin salt in the aprotic solvent with the selenourea to form a metal solution; and coating the metal solution onto a substrate to form an Ag2ZnSn(S,Se)4 compound layer on the substrate.
