Patent ID: 8481419

Claim:
Method for producing at least one electrically conducting metal contact, strip-shaped in particular, on a semiconductor component, such as, a solar cell, which presents, on the surface on a semiconductor coating, a coating, such as, a dielectric coating, such as, a passivation coating, comprising the process steps, line-, strip- and/or point-shaped application of a fluid to the coating, which contains at least particles made of metal, and particles made of glass frit, hardening of the fluid by heat treatment with simultaneous formation of: cohesive metal structure for sintering the metal particles together, a glass layer between the metal structure and the semiconductor substrate, and metal areas in the semiconductor substrate, which are deposited by the glass layer from the metal structure on the semiconductor substrate, removal of the separating glass layer by etching, and thus simultaneous removal of the metal structure, without removal of the metal areas which have grown into the semiconductor substrate, for the formation of the at least one electrically conductive contact, intermediate coating-free deposition of electrically conducting material from a solution onto the metal areas of the semiconductor component, which have grown into the semiconductor component, where, above the metal areas, the glass layer and metal structure coating have been removed, with simultaneous electrically conducting connection of the metal areas present in these areas in the substrate.
