Abstract
A method for fabricating a solar cell and the and the resulting structures, e.g., micro-electronic devices, semiconductor substrates and/or solar cells, are described. The method can include: providing a solar cell having metal foil having first regions that are electrically connected to semiconductor regions on a substrate at a plurality of conductive contact structures, and second regions; locating a carrier sheet over the second regions; bonding the carrier sheet to the second regions; and removing the carrier sheet from the substrate to selectively remove the second regions of the metal foil.
