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.
