SELECTIVE SELF-ALIGNED PLATING OF HETEROJUNCTION SOLAR CELLS

摘要

A method for forming contacts on a photovoltaic device includes forming a heterojunction cell including a substrate, a passivation layer and a doped layer and forming a transparent conductor on the cell. A patterned barrier layer is formed on the transparent conductor and has openings therein wherein the transparent conductor is exposed through the openings in the barrier layer. A conductive contact is grown through the openings in the patterned barrier layer by a selective plating process.
