Thickening a contact grid of a solar cell for increased efficiency. A mold containing soldering material is heated. The mold is aligned with the contact grid such that the soldering material is in physical contact with the contact grid. The mold is re-heated, transferring the solder material from the mold to the contact grid to create a thickened contact grid.
