A method for manufacturing a photovoltaic cell with a selective emitter, including the steps of: depositing an antireflection layer including n-type dopants on an n- or p-type silicon substrate, said deposition being, performed in the presence of a chemical compound that accelerates the diffusion of n-type dopant atoms in said substrate; overdoping at least one area of the substrate to form at least one n++ overdoped emitter by local diffusion of the n dopants of at least one area of the antireflection layer; depositing at least one n-type conductive material on the at least one n++ overdoped emitter; and at least one p-type conductive material on the surface of the substrate opposite to that including the antireflection layer; forming the n contacts and the p contacts simultaneously to the forming of an n+ emitter by an anneal capable of diffusing within the substrate n dopants from the antireflection layer. |
