  • Photovoltaic Cell with Efficient Finger and Tab Layout
    Publication number: 20100000602
    Abstract: A photovoltaic cell has a photosensitive substrate, a plurality of fingers in ohmic contact with the substrate, and a plurality of pads on the substrate. The plurality of pads effectively form a plurality of discontinuous busbars. Two of the fingers extend from a first pad of the plurality of pads. Specifically, a given one of the two fingers (“given finger”) may connect with a second pad of the plurality of pads. This given finger may have an inter-pad portion between the first and second pads. The cell further has a tab at least partially covering the inter-pad portion of the given finger.

  • Photovoltaic Panel and Cell with Fine Fingers and Method of Manufacture of the Same
    Publication number: 20090159114
    Abstract: A photovoltaic cell has a photosensitive substrate and a plurality of fingers in ohmic contact with the substrate. At least one of the fingers has an average width of less than about 95 microns. The cell also has a plurality of busbars in ohmic contact with the fingers. At least two of the busbars that are spaced less than about 38 millimeters apart intersect the at least one finger (i.e., the finger(s) having an average width of less than about 95 microns).
