EDGE DELETION OF THIN-LAYER SOLAR MODULES BY ETCHING

摘要

The present invention relates to a rapid and low-cost method, which can be carried out locally, for the wet-chemical edge deletion of "solar modules", in which etching pastes which are suited for this purpose are applied and removed once the reaction of the paste remains is completed or the substrate surface is cleaned in a suitable manner. The method uses a newly developed etching paste for such purpose.
