Integrated back-sheet assembly for photovoltaic module

A process for forming a back-sheet assembly for a photovoltaic module having multiple solar cells with back-side electrical contacts, comprising:

• providing a substrate having a back surface and a front surface;
• adhering an electrically conductive metal circuit to the front surface of said substrate;
• adhering a plurality of release pads to the electrically conductive metal circuit in a pattern;
• adhering an insulating layer to said electrically conductive metal circuit over said electrically conductive metal circuit and said release pads;
• forming a plurality of openings in said insulating layer in a pattern corresponding to the pattern in which the release pads are adhered to the electrically conductive metal circuit;
• and
• filling said plurality of openings in said insulating layer with an electrically conductive material such that the electrically conductive material is in electrical contact with said electrically conductive metal circuit.
