Abstract
A method for forming a contact region for a solar cell is disclosed. The method includes depositing a paste composed of a first metal above a substrate of the solar cell, curing the paste to form a first metal layer, electrolessly plating a second metal layer on the first metal layer and electrolytically plating a third metal layer on the second metal layer, where the second metal layer electrically couples the first metal layer to the third metal layer. The method can further include electrolytically plating a fourth metal layer on the third metal layer.
