Abstract (en)
[origin: WO2012135395A2] 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.
