Abstract
A passivation layer is deposited on a first portion of a region of the solar cell. A grid line is deposited on a second portion of the region. The passivation layer is annealed to drive chemical species from the passivation layer to deactivate an electrical activity of a dopant in the first portion of the region of the solar cell.
