  • Patent number: 7670937
    Abstract: Method for producing doped regions on the rear face of a photovoltaic cell. A doping paste with a first type of conductivity is deposited on a rear face of a semiconductor-based substrate according to a pattern consistent with the desired distribution of regions doped with the first type of conductivity. Then, an oxide layer is deposited at least on the portions of the rear face of the substrate not covered with the doping paste. Finally, an annealing of the substrate diffuses the doping agents in the substrate and forms doped regions under the doping paste.
