Abstract: A screen printing form (1, 1?) for use in screen printing, in particular for producing a metallic contact structure of a photovoltaic solar cell, having a woven screen printing fabric (1b) with a plurality of elongate woven fabric elements, which are arranged in a first element direction and a second element direction perpendicular thereto, and a stencil (1c), arranged on the woven screen printing fabric (1b) that has at least one opening formed as straight channel with a channel width BK. The woven fabric elements have a spacing AF in the first element direction and a spacing which deviates by less than 5% from AF in the second element direction, and the woven fabric elements have a diameter DG in the first element direction and a diameter which deviates by less than 5% from DG in the second element direction. A screen printing device and screen printing form are also provided.

Abstract: 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.
