Abstract (en)
[origin: WO2010049229A2] The invention relates to a method for producing a solar cell from (a) an n-doped semiconductor substrate, especially from silicon, which has a main surface that serves as the light incidence side when used and a second main surface that serves as the back, an n+ region, front surface field, configured in the first main surface, and an p+ emitter configured in the second main surface by doping with aluminum, or (b) a p-doped substrate, especially silicon, which has an n+ emitter configured on the first main side and an p+ region, i.e. a back surface field, configured in the second main surface by doping with aluminum, the doping with aluminum being carried out by diffusion of the aluminum from an aluminum-containing source layer applied to the second main surface, in such a manner that the Al concentration profile, starting from the second main surface towards the semiconductor substrate, substantially has a profile where the highest Al concentration is on the second main surface or directly next to it.
