Document Type and Number:
WIPO Patent Application WO/2019/054550
Kind Code:
A1
Abstract:
According to one aspect of the present invention, provided is a chalcogenide solar cell comprising: a substrate; a transparent conductive oxide back electrode formed on the substrate; a chalcogenide light-absorbing layer formed on the transparent conductive oxide back electrode, and comprising at least Cu, Ga and Ag; and a transparent conductive oxide front electrode formed on the chalcogenide light-absorbing layer, wherein a Cu-excess region, in which a Cu content is relatively higher than the average Cu content of the chalcogenide light-absorbing layer, is formed in the interface region at which the chalcogenide light-absorbing layer comes in contact with the transparent conductive oxide back electrode.
