Abstract
A solar cell comprising a base layer of p-doped silicon and an emitter layer of n-doped silicon, where an electrode is arranged regionally on the emitter layer and optionally it passivation layer is arranged regionally on the back surface of the base layer and a layer of a dielectric, the entire area of which is covered with a metal layer, is arranged regionally thereon, where the metal layer is in electrically conducting contact via an interlayer with the base layer over the regions not covered by the layer of dielectric and the interlayer comprises a mixed phase from the material of the passivation layer and the material of the metal layer. The present invention further relates to a method of production of said solar cell.
