  • High Speed Copper Plating Process
    Publication number: 20140256083
    Abstract: A copper electrolyte comprising a copper nitrate salt is described. The electrolyte is suitable for use in a light induced plating process for metallizing contacts in a photovoltaic solar cell. A method of metallizing an electrical contact in a photovoltaic solar cell using the copper electrolyte is also described.

  • Surface treatment of silicon
    Patent number: 7989346
    Abstract: A method of forming a resist pattern on a silicon semiconductor substrate having an anti-reflective layer thereon is described. The method includes the steps of a) modifying surface energy of the anti-reflective surface with a chemical treatment composition, b) applying a UV etch resist to the treated anti-reflective surface, and c) exposing the anti-reflective surface to a wet chemical etchant composition to remove exposed areas of the anti-reflective surface. Thereafter, the substrate can be metallized to provide a conductor pattern. The method may be used to produce silicon solar cells.
