摘要： A method for producing a metallic contact structure for making electrical contact with a photovoltaic solar cell, wherein, in order to create the contact structure, a paste, which contains metal particles, is applied to a surface of a carrier substrate via at least one dispensing opening, wherein the dispensing opening and the carrier substrate are moved in relation to one another during the dispensing of the paste. The paste is circulated in a circulating region, and in each case a part of the paste is branched off out of the circulating region at a plurality of branching points and each branching point is assigned at least one dispensing opening, via which the paste branched off at the branching point is applied to the surface of the carrier substrate, wherein the paste flows through a flow path having a length of less than 1 cm in each case between being branched off out of the circulating region and being dispensed from the dispensing opening assigned to the branching point. A device for producing a metallic contact structure for making electrical contact with a photovoltaic solar cell is also provided.
