Metallization is performed onto the front and the rear sides of the silicon panels to form conducting channels. During metallization, metals (Ag, Cu, Ni) are used to form the electrodes on the surface of solar cell panels. Because metals are not transparent to solar radiation, electrode coverage in the front side, where the
Formation of ohmic metal contacts to diffused and non-diffused Si wafers is perhaps the single most critical process in solar cell fabrication; it is also the final step. Figure
