PHOTOVOLTAIC CELL AND METHOD FOR MANUFACTURING SUCH A PHOTOVOLTAIC CELL

WIPO Patent Application WO/2014/196860

A3

A photovoltaic cell includes a semiconductor substrate of a first conductivity type, with a first surface arranged with a highly doped surface field layer of the first conductivity type. The substrate has on the highly doped surface field layer at least one contacting area for contacting the surface field layer with a respective contact. In the first surface at the location of said at least one contacting area a doping concentration in the highly doped surface field layer is increased relative to the doping concentration in the surface area outside the first contacting area, and in the first surface at the location of each contacting area the highly doped surface field layer has a profile depth that is larger than a profile depth of the doped surface field layer outside the contacting area.
