摘要
The invention relates to a method for producing a front-side emitter electrode as a front contact for a silicon solar cell on a silicon wafer, wherein a recess is generated in the front side thereof. A front-side n-doped silicon layer and an antireflection layer are then generated. A paste is then introduced into the recess by means of an inkjet printer, said paste comprising electrically conductive metal particles and corrosive glass frit etching through the antireflection layer to the n-doped silicon layer and electrically contacting the same. Electrically conductive front contact metal is subsequently galvanically deposited in the recess on the tempered paste as a front contact.
