Problems solved by technology
In the transition zone of the overall development, where the developments of different screens (using known screens) are adjacent to each other, inhomogeneities may appear throughout the development due to the above-mentioned distortions of the individual partial developments
[0008] In addition, when using screens, due to the large opening surface of the developed pattern of the screen, very fine filaments are required to stabilize the screen, but are easily damaged, thus only allowing a short service life

Abstract
The present invention relates to a printing stencil (2), for example for applying a contact (contact fingers 101, busbar / busbars 102) to a substrate (1) of a solar cell (100) and to a method for producing a printing stencil (2) of this type. The printing stencil (2) comprises a carrier layer (21) and a structure layer (22) which lies under the carrier layer (21), wherein the structure layer (22) has at least one printing image opening (23a) which corresponds to at least part of the printing image of the contact (contact fingers 101, busbar / busbars 102), the carrier layer (21) has one or more carrier layer openings (23b), and the one or more carrier layer openings (23b) overlap in a plan view of the printing stencil (2) with the printing image opening (23a), in such a way that the printing stencil (2) has an opening (23) which is formed from the at least one printing image opening (23a); and the one or more carrier layer openings (23b) and is suitable for applying contact material to the substrate (1) through the opening (23).
Description
technical field [0001] The invention relates to a development template for applying a development pattern (especially contact) on a substrate (especially a solar cell substrate), the development template includes a carrier layer and a structural layer, the structural layer is located below the carrier layer, The structural layer has at least one development opening, the at least one development opening is at least a portion of the development corresponding to the development pattern, and the carrier layer has one or more carrier layer openings. [0002] The invention also relates to a method for producing a development template for applying a development pattern (in particular a contact) to a substrate, in particular a solar cell substrate, the development template comprising a carrier layer and a structural layer, the structural layer being positioned on Below the carrier layer, the structural layer has at least one development opening, the at least one development opening is...
