  • Publication number: 20120204946
    Abstract: In a method for producing a front-side emitter electrode as front contact for a silicon solar cell on a silicon wafer, a depression is produced in the front side of said silicon wafer. A front-side n-doped silicon layer and an antireflection layer are then produced. A paste is then introduced into the depression, said paste containing electrically conductive metal particles and etching glass frit. Said paste, as a result of momentary heating, etches through the antireflection layer to the n-doped silicon layer making electrical contact with the latter. Afterwards, electrically conductive front contact metal is galvanically attached as front contact onto the heat-treated paste in the depression.
