NOVELTY - Manufacturing back-contact solar cell module involves providing solar cell (58) array having electrical contacts; forming openings in polymeric interlayer dielectric layer, having holes aligned over electrical contacts; providing polymeric wire mounting layer adhered with electrically conductive wires (42); heating electrically conductive binder in holes of dielectric layer; thermally laminating polymeric back-sheet (31), including solar cell array layers after conductive wires have been physically and electrically attached to electrical contacts of solar cells by the binder.    USE - For manufacturing back-contact solar cell module (claimed) with electrically conductive circuits integrated into the back of the modules.    ADVANTAGE - The polymeric wire mounting layer and polymeric interlayer dielectric layer are comprised of polymer encapsulant material that have high transparency, high impact resistance, high penetration resistance, high moisture resistance, good ultraviolet light resistance, good long term thermal stability, adequate adhesion strength to front sheets, back-sheets, other rigid polymeric sheets and cell surfaces, and good long term weatherability. The metal wires are coated with solder and optionally with a flux, which can more easily be welded to the back contacts of the solar cells with reduced amount of the coating material used. The conductive wires are coated with electrically insulating material such as plastic sheath, which helps to prevent short circuits in the solar cells when the wires are positioned over the back of an array of solar cells. The electrically conductive wires having cross sectional shape, which provides strength, current carrying ability, low bulk resistivity, and wire handling properties desired for module efficiency and manufacturability.    DETAILED DESCRIPTION - Manufacturing back-contact solar cell module involves providing solar cell (58) array having solar cells, where each cell has front light receiving surface, active layer to generate electric current, and rear surface opposite to front surface, having positive and negative polarity electrical contacts, and at least two of solar cells are arranged in column; providing polymeric interlayer dielectric layer having opposite first and second sides; forming openings in dielectric layer which are arranged in columns extending in the lengthwise direction of dielectric layer, and placing first side on rear surfaces of solar cells, where the holes in dielectric layer are aligned over electrical contacts on rear surface; providing polymeric wire mounting layer having opposite first and second sides; providing elongated electrically conductive wires (42) and adhering conductive wires to first side in lengthwise direction of wire mounting layer, where each conductive wire has cross sectional area of 70 square mils (miles) along their length, and are not touching each other upon being adhered to wire mounting layer, and extending at least the length of column of solar cells; placing first side of wire mounting layer on dielectric layer where conductive wires on first side are over the openings in one of the column of openings in dielectric layer; providing electrically conductive binder in holes of dielectric layer, and heating the binder such that the binder physically and electrically attaches electrically conductive wires to the positive and negative electrical contacts on solar cells through the openings; providing polymeric back-sheet (31) over second side of wire mounting layer; thermally laminating polymeric back-sheet, wire mounting layer, dielectric layer and solar cell array after conductive wires have been physically and electrically attached to electrical contacts on rear surface of the solar cells by the binder.
