Abstract:
An integrated back sheet for a back-contact solar cell module and a back-contact solar cell module made with such an integrated back-sheet are provided. Processes for making such integrated back-sheets and back-contact solar cell modules are also provided. Elongated electrically conductive wires that extend at least two times the length of solar cells in the back-contact cell module are mounted on a layer of the integrated back-sheet. The elongated conductive wires of the integrated back-sheet electrically connect to solar cell back contacts when the back-sheet is used in a back-contact photovoltaic module.
