Abstract:
Fabrication methods and structures relating to backplanes for back contact solar cells that provide for solar cell substrate reinforcement and electrical interconnects are described. The method comprises depositing an interdigitated pattern of base electrodes and emitter electrodes on a backside surface of a semiconductor substrate, attaching a prepeg backplane to the interdigitated pattern of base electrodes and emitter electrodes, forming holes in the prepeg backplane which provide access to the first layer of electrically conductive metal, and depositing a second layer of electrically conductive metal on the backside surface of the prepeg backplane forming an electrical interconnect with the first layer of electrically conductive metal through the holes in the prepeg backplane.

Abstract:
High productivity thin film deposition methods and tools are provided wherein a thin film semiconductor material layer with a thickness in the range of less than 1 micron to 100 microns is deposited on a plurality of wafers in a reactor. The wafers are loaded on a batch susceptor and the batch susceptor is positioned in the reactor such that a tapered gas flow space is created between the susceptor and an interior wall of the reactor. Reactant gas is then directed into the tapered gas space and over each wafer thereby improving deposition uniformity across each wafer and from wafer to wafer.
