Abstract:
1. A method for forming a photovoltaic cell electrode structure, wherein the photovoltaic cell comprises a semiconductor substrate having a passivation layer thereon, the method comprising: providing a plurality of contact openings through the passivation layer to the semiconductor substrate; selectively plating a contact metal into the plurality of contact openings to deposit the contact metal; depositing at least one metal containing layer over the deposited contact metal to form metal gridlines; and firing the deposited contact metal and the at least one deposited metal containing layer, wherein the method further comprises depositing a self-assembled monolayer material on the passivation layer following forming the plurality of contact openings in the passivation layer at portions on and surrounding one or more of the plurality of contact openings, and wherein the selective plating of the contact metal deposits the contact metal on the self- assembled monolayer and in the plurality of contact openings.
