Abstract
The present invention relates to a novel printable etching medium having non-Newtonian flow behavior for the etching of surfaces in the production of solar cells and to the use thereof. In particular, the invention relates to corresponding particle-containing compositions by means of which extremely fine structures can be etched very selectively without damaging or attacking adjacent areas.
