Shingled solar cell module

摘要

A high efficiency configuration for a solar cell module comprises solar cells arranged in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency.

主权项

1. A method comprising:
providing a silicon solar cell wafer; scribing one or more scribe lines on the silicon solar cell wafer to define a plurality of rectangular solar cell regions; applying an electrically conductive adhesive bonding material to portions of a top surface of the solar cell wafer; supporting a bottom surface of the solar cell wafer on a moving perforated belt and transporting the solar cell wafer with the perforated belt over a curved portion of a vacuum manifold; applying a vacuum from the vacuum manifold through the perforated belt to the bottom surface of the solar cell wafer to flex the solar cell wafer against the curved portion of the vacuum manifold and thereby cleave the solar cell wafer along the scribe lines to provide a plurality of rectangular solar cell strips each corresponding to one of the rectangular solar cell regions and each comprising a portion of the electrically conductive adhesive bonding material disposed on its top surface adjacent a long side; arranging the plurality of rectangular silicon solar cell strips in line with long sides of adjacent rectangular silicon solar cell strips overlapping in a shingled manner with a portion of the electrically conductive adhesive bonding material disposed in between; and curing the electrically conductive bonding material, thereby bonding adjacent overlapping rectangular silicon solar cell strips to each other and electrically connecting them in series.
