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.

Printing stencil for producing a structure of an electronic component, in particular of a photovoltaic solar cell, and method for producing a printing stencil of this type

A screen printing form (′) for use in screen printing, in particular for producing a metallic contact structure of a photovoltaic solar cell, having a woven screen printing fabric () 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 (), arranged on the woven screen printing fabric () 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.
