Abstract
A method for producing a photovoltaic solar cell, including the following steps: A. texturizing a front () of a semiconductor substrate; B. generating a selective emitter doping on the front () of the semiconductor substrate by generating on the front () a first low-doped region () and a local high-doped region () within the first low-doped region; and C. applying at least one metal emitter contact structure to the front () of the semiconductor substrate, at least in the regions of local high doping, wherein, between method steps B and C, a respective silicon oxide layer () is generated in a method step Bsimultaneously on the front and back of the semiconductor substrate via thermal oxidation.
