Abstract
A solar cell can include a substrate and a semiconductor region disposed in or above the substrate. Selective firing of a conductive paste can be used to form a conductive contact for a solar cell. The solar cell can also include a conductive contact disposed on the semiconductor region with the conductive contact including a conductive paste that has a top and bottom portion with the top portion having particles coalesced together.
