NOVELTY - The rear-contact solar cell interconnect comprises a first conductive foil (110) with an opening, a second conductive foil (130), a first insulating layer arranged between the first conductive foil and the second conductive foil, a second insulating layer coupled to a back surface of the second conductive foil, and a backsheet mechanically supporting the first conductive foil, the first insulating layer, and the second conductive foil. The first conductive foil is arranged to be electrically connected to a first polarity contact (102) on a rear side of a first rear-contact solar cell.    USE - The interconnect is useful for a rear-contact solar cell including a metal wrap-through cell, an emitter wrap-through cell, a back junction cell, an all-back-contact cell, an interdigitated back contact cell, a rear point-contact cell, a rear-contact-adapted passivated emitter rear locally-diffused cell and a rear-contact-adapted silicon heterojunction cell (claimed).    ADVANTAGE - The rear-contact solar cell interconnect improves the conversion efficiency and throughput and reduces the manufacturing cost of the solar cell, and prevents warpage and breakage of the rear-contact solar cells by minimizing handling and/or reducing the level of CTE-mismatch-induced mechanical stress placed on the rear-contact solar cells during fabrication.    DETAILED DESCRIPTION - The rear-contact solar cell interconnect comprises a first conductive foil (110) with an opening, a second conductive foil (130), a first insulating layer arranged between the first conductive foil and the second conductive foil, a second insulating layer coupled to a back surface of the second conductive foil, and a backsheet mechanically supporting the first conductive foil, the first insulating layer and the second conductive foil. The first conductive foil is arranged to be electrically connected to a first polarity contact (102) on a rear side of a first rear-contact solar cell and a second polarity contact (104) on a rear side of a second rear-contact solar cell, has a thickness of 25-100 mu m, and is configured to be electrically connected to a third conductive foil that is electrically connected to a second rear-contact solar cell. The first conductive foil and the first insulating layer are arranged to be mechanically coupled with the first and second rear-contact solar cells. The second conductive foil and the second insulating layer are mechanically coupled with the first rear-contact solar cell and a third rear-contact solar cell. The second conductive foil is arranged to be electrically connected to the second polarity contact on the rear side of the first rear-contact solar cell through the opening of the first conductive foil, and is arranged to be electrically connected to the first polarity contact on a rear side of the third rear-contact solar cell. The solar cells include a first surface arranged to receive solar irradiation, and a second surface opposite to the first surface. The first polarity contact and the second polarity contact are provided on the second surface of the solar cell. The first insulating layer has an opening that partially overlaps the opening in the first conductive foil, and is coupled to a back surface of the first conductive foil. The opening of the first conductive foil is arranged to allow an electrical connection between the second polarity contact and the second conductive foil to pass through the opening of the first conductive foil with a clearance that partially electrically isolates the electrical connection from the first conductive foil. A width of the opening in the first conductive foil is 1-5 mm. A critical feature size of the electrical connection inside the opening of the first conductive foil is 1 -3 mm. A width of the clearance is 1 mm. An insulating material covers a portion of the inside of the opening in the first conductive foil, and is an adhesive that is used to attach the first conductive foil to the solar cell. A portion of the second conductive foil is coupled to a portion of the first insulating layer. An INDEPENDENT CLAIM is included for a method for assembling a rear-contact solar cell interconnects.
