A method for producing a rear-side contact system for a silicon thin-film solar cell having a pn junction formed from a silicon absorber layer and an emitter layer includes applying an organic insulation layer to the emitter layer; producing contact holes in the insulation layer as far as the absorber layer and the emitter layer; subsequently insulating the contact holes; subsequently applying a low-melting metal layer to form n and p contacts in the contact holes; separating the metal layer into n-contacting and p-contacting regions by laser-cutting; before applying the organic insulation layer to the emitter layer, applying a TCO layer; producing holes for contacts for the silicon absorber layer in the organic insulation; and subsequently selectively doping the produced holes for the contacts as far as the silicon absorber layer.
