  • Solar cell metallization
    Patent number: 9911875
    Abstract: An interdigitated back contact solar cell is provided. The solar cell comprises a solar cell substrate having a light receiving frontside and a backside comprising base and emitter regions. A first level metal (M1) layer is positioned on the substrate backside contacting the base and emitter regions. A second level metal (M2) layer is connected to the first level metal (M1) layer and comprises a base busbar and an emitter busbar. The first level metal comprises substantially orthogonal interdigitated metallization and substantially parallel interdigitated metallization positioned under and corresponding to the base and emitter busbars on the second level metal (M2). The substantially parallel interdigitated metallization of M1 collects carriers of opposite polarity of the corresponding busbar.

  • ACTIVE BACKPLANE FOR THIN SILICON SOLAR CELLS
    Publication number: 20160013335
    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.
