    Abstract: A method for producing a solar cell from a silicon wafer, including the following process steps: A) texturizing one side of the silicon substrate (1) for improving the absorption or removing saw damage on one side of the silicon substrate (1); B) generating an emitter area (2) on one side of the silicon substrate (1) by diffusing in a doping material for forming a pn transition; C) removing a glass layer which comprises the doping material; D) applying a masking layer (3) which is a dielectric layer; E) removing one part of the material of the silicon substrate (1); F) applying metal structures (5, 6) for electrically contacting the solar cell. It is significant that thermal oxidation is performed between the process steps E and F for forming an oxide layer (4) and that the masking layer (3) and the oxide layer (4) remain on the silicon substrate (1) in the subsequent process steps.
