  • Integrated back-sheet assembly for photovoltaic module
    Patent number: 9882078
    Abstract: A process for forming a back-sheet assembly for a photovoltaic module having multiple solar cells with back-side electrical contacts includes providing a substrate, adhering an electrically conductive metal circuit to the substrate, adhering release pads to the metal circuit in a pattern, adhering an insulating layer to the metal circuit, forming openings in said insulating layer in a pattern over the release pads, and filling the openings with electrically conductive material that is in electrical contact with the electrically conductive metal circuit. A process for forming a photovoltaic module with this back-sheet assembly is also provided. The back-sheet assembly and photovoltaic module made with the back-sheet assembly are also provided.
    Type: Grant
