Patent Number: 7,825,329

Title: Thin film solar cell manufacturing and integration

Abstract: A method of forming a Group IBIIIAVIA solar cell absorber which includes an active portion and an electrically resistive portion. The absorber is interposed between a base layer and a transparent conductive layer. The electrically resistive portion increases resistance between the base layer and a connector layer that is formed on the transparent conductive layer. The connector layer comprises the busbar and the fingers of the solar cell. The busbar is preferably placed over the electrically resistive portion while the fingers extend over the active portion of the absorber layer.
