A solar cell can include a first plurality of metal contact fingers, and a second plurality of metal contact fingers interdigitated with the first plurality of metal contact fingers, wherein at least one of the first plurality of metal contact fingers comprises a wrap-around metal finger that passes between a first edge of the solar cell and at least one contact pads. A photovoltaic (PV) string including a solar cell with a wrap-around metal contact finger. A method of coupling an electrically conductive connector to a solar cell with a wrap-around metal contact finger.

Solar cell with wraparound finger

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.
