Abstract: A printing stencil (1) for forming conductor tracks on a substrate. The printing stencil (1) has a plurality of cutouts in the form of printing gaps (4) for forming the conductor tracks. Each printing gap (4) of the plurality of printing gaps (4) has at least one print definition region (3) adjacent to the printing side and at least one printing medium supply region (2) adjacent to the squeegee side, the volume of the print definition region (3) being smaller than the volume of the printing medium supply region. Moreover, a printing device for forming conductor tracks on a substrate and a method for producing a metallic contact structure of a photovoltaic solar cell are also provided.

Abstract: A printing form for producing a structure of an electronic component, in particular a photovoltaic solar cell, having a screen frame and a screen, which is in the form of a sheet-like textile and has a multiplicity of elongate screen elements. The screen is arranged in the screen frame and the screen has at least one printing region which a printing paste can permeate and at least one barrier region which the printing paste cannot permeate. The elongate screen elements are made from glass fiber, carbon fiber and/or carbon nanotubes.

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.
