Abstract (en)

[origin: WO2010099863A2] The invention relates to a method for producing front-and-back contact solar cells. Said method is based on microstructuring a wafer that has a dielectric layer, and doping the microstructured areas. 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.
