Abstract
The invention relates to a method and to a device for the mechanical structuring of thin-film solar cells which are carried on a flexible carrier layer in the form of a material web. The material web is held on a support, where the groove areas, into which grooves are introduced for structuring with a mechanical scoring tool, are pulled onto elastic bases, by holding the material web by frictional engagement over adjacent groove-free areas.
Claims7
A method for the mechanical structuring of thin-film solar cells carried on a material web flexible carrier layer thereby forming a layer structure, comprising, holding a section of said material web on a support, moving a scoring tool linearly relative to said support to score grooves in predetermined groove areas of said section of material web into said layer structure over holding areas that lie between said groove areas, by frictional engagement on said support, and said groove areas are pulled on elastic bases.
A device for the mechanical structuring of thin-film solar cells carried on a material web flexible carrier layer thereby forming a layer structure, by scoring grooves having a predetermined mutual separation that are arranged parallel to or at a right angle to a side edge of said material web, comprising
- a support on which said material web lies at least in sections during said scoring, said support having score areas arranged so as to coincide with the arrangement of said grooves, said score areas formed by elastic material, and holding areas located between said score areas over which said material web section is held on said support,
- a scoring tool, and
- means for effecting relative movement of said scoring tool with respect to said material web along said grooves.
