Abstract
A process for producing front and rear contacts on a solar cell provides for producing a channel structure on the passivation layer of a silicon wafer, producing a rear contact by printing and firing a silver paste that has an aluminum dopant, treating the wafer with a palladium solution containing fluoride to produce a nucleation layer on the surface of the channel structure, and reinforcing the nucleation layer by depositing a further metal.
