摘要:
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.
摘要:
The present invention relates to particle-containing etching media in the form of etching pastes which are suitable for the full-area or selective etching of extremely fine lines or structures in silicon surfaces and layers and in glass-like surfaces formed from suitable silicon compounds. The present invention also relates to the use of the pastes according to the invention in processes for etching surfaces of this type.
