Abstract: Back contact back junction solar cell and methods for manufacturing are provided. The back contact back junction solar cell comprises a substrate having a light capturing frontside surface with a passivation layer, a doped base region, and a doped backside emitter region with a polarity opposite the doped base region. A backside passivation layer and patterned reflective layer on the emitter form a light trapping backside mirror. An interdigitated metallization pattern is positioned on the backside of the solar cell and a permanent reinforcement provides support to the cell.

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 prepreg backplane to the interdigitated pattern of base electrodes and emitter electrodes, forming holes in the prepreg 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 prepreg backplane forming an electrical interconnect with the first layer of electrically conductive metal through the holes in the prepreg backplane.
