PHOTOVOLTAIC SOLAR CELL AND METHOD OF PRODUCTION THEREOF

摘要

The present invention relates to a solar cell (100) comprising a base layer (101) of p-doped silicon and an emitter layer (102) of n-doped silicon, where an electrode (103) is arranged regionally on the emitter layer (102) and optionally a passivation layer (104) is arranged regionally on the back surface of the base layer (101) and a layer (105) of a dielectric, the entire area of which is covered with a metal layer (106), is arranged regionally thereon, where the metal layer (106) is in electrically conducting contact via an interlayer (108) with the base layer (101) over the regions (107) not covered by the layer of dielectric (105) and the interlayer (108) consists of a mixed phase from the material of the passivation layer and the material of the metal layer (106). The present invention further relates to a method of production of said solar cell.
