1. A method comprising:
- depositing metal in a pattern on the front side of a photovoltaic cell formed on a semiconductor wafer to have a front side and a back side, the cell producing electricity when the front side is illuminated;
annealing the photovoltaic cell after depositing metal;
placing a plurality of photovoltaic cells on a carrier;
wiring the plurality of photovoltaic cells together using flex connectors to form an electrical connection between and among the plurality of photovoltaic cells; and
depositing a passivation layer on each of the plurality of photovoltaic cells after wiring the plurality of photovoltaic cells together.

Abstract
A photovoltaic module and a method of manufacturing such a module in which metal is deposited in a pattern on the front side of a semiconductor wafer which acts as an electrode. Photovoltaic cells manufactured using a semiconductor wafer typically have a P type semiconductor region and an N type semiconductor region. The metal on the front side of each of the photovoltaic cells forms an electrical connection to the doped layer of the semiconductor wafer on its front side.
