Title: Method for forming silver-copper mixed kesterite semiconductor film

Abstract

After forming a layer of a Cu-deficient kesterite compound having the formula Cu.sub.2-xZn.sub.1+xSn(S.sub.ySe.sub.1-y).sub.4, wherein 0<1, and 0.ltoreq.y.ltoreq.1, on a substrate and forming a Ag layer on the Cu-deficient kesterite compound layer, the Cu-deficient kesterite compound layer and Ag layer are annealed in a S- and/or Se-rich ambient to provide a film containing a Ag--Cu mixed kesterite compound having the formula Ag.sub.xCu.sub.2-xZnSn(S.sub.ySe.sub.1-y).sub.4, wherein 0<2, and 0.ltoreq.y.ltoreq.1.
