Abstract (en)
[origin: WO2010099892A2] The invention relates to a method for producing rear contact solar cells. Said method is based on microstructuring a wafer that has a dielectric layer, doping the microstructured areas on the rear side, and diffusing an emitter on the front side. A metal-containing seed layer is then deposited, and the contacts are galvanically reinforced. The invention also relates to solar cells that can be produced using said method.
