Abstract:
An assembly technique for assembling solar cell arrays is provided. During the fabrication of a solar cell, openings through the semiconductor layer are etched through to a top surface of the backmetal layer. The solar cells include an exposed top surface of the backmetal layer. A plurality of solar cells are assembled into a solar cell array where adjacent cells are interconnected in an electrically serial or parallel fashion solely from the top surface of the solar cells.
Abstract:
The method of the invention includes the sequential steps of providing a plurality of solar cells, interconnecting the solar cells using one or more interconnect tabs, attaching the interconnect tabs to a top side of the solar cell to interconnect the plurality of solar cells by coupling an exposed top surface of a first solar cell to a top surface of an adjacent second solar cell, attaching one or more bypass diodes to a top side of the solar cell, then next applying an adhesive to a first film layer, placing the plurality of solar cells onto the first film layer, then next applying an adhesive to a second film layer, placing the plurality of solar cells and first film layer onto the second film layer to form a sheet assembly, and then forming the solar sheet from the sheet assembly.
