摘要： A single-side contacted solar cell and method for production of a single-side contacted solar cell provide a direct arrangement of a contact grid on one side of an absorber layer. A free surface of the contact grid is coated with an electrically non-conducting insulation layer. An emitter layer is deposited on a whole surface such that the contact grid is arranged between the absorber layer and the emitter layer. The emitter layer is provided with a contact layer. For back face contact, the emitter layer is arranged on a back face of the absorber layer to avoid additional absorptive losses.

摘要： A thin-film solar module contacted on one side includes a support layer, a photoactive absorber layer and at least one dopant layer deposited over a surface area of at least one side of the absorber layer so as to form a thin-film packet that is divided into thin-film solar cell areas by insulating separating trenches. The thin-film solar module includes first and second contact systems. The first contact system includes contacts connected by an outer contact layer. The second contact system consists of an inner contact layer covering a side of the solar cell areas that face away from the support layer so as to separately discharge excess charge carriers generated by incident light in the absorber layer. The second contact system includes structures that surround and electrically insulate the contacts, which extend through the inner contact layer from the outer contact layer. The first and second contact systems are electrically conductive and connected in series by series contacts in interconnection areas and electrically insulated from each other by an insulation layer outside of the interconnection areas.

摘要： A method for the production of a wafer-based, back-contacted heterojunction solar cell includes providing at least one absorber wafer. Metallic contacts are deposited as at least one of point contacts and strip contacts in a predetermined distribution on a back side of the at least one absorber wafer. The contacts have steep flanks that are higher than a cumulative layer thickness of an emitter layer and an emitter contact layer and are sheathed with an insulating sheath. The emitter layer is deposited over an entire surface of the back side of the at least one absorber wafer. The emitter contact layer is deposited over an entire surface of the emitter layer so as to form an emitter contact system. At least one of the emitter layer and the emitter contact layer is selectively removed so as to expose the steep flanks of the contacts that are covered with the insulating sheath. An insulation layer is deposited over an entire surface of the emitter contact layer so as to provide a narrow contact web at an edge of the at least one absorber wafer. End areas of the steep flanks of the contacts that are covered by the insulation layer are exposed. At least one of an absorber contact layer and an absorber contact grid is deposited over an entire surface of the insulation layer and over the exposed end areas of the steep flanks so as to form the absorber contact system, so as to provide the heterojunction solar cell with the contact web and with the at least one of an absorber contact layer and an absorber contact grid of the absorber contact system.
