摘要:
The present invention relates to an activation composition for activation of silicon substrates, which is an aqueous solution comprising a source of palladium ions, a source of fluoride ions and at least two aromatic acids. The present invention further relates to a method for its use and optionally for subsequent metallization of such treated substrates. The method can be employed in semiconductor and solar cell manufacturing.
