  • Patent number: 9666749
    Abstract: The instant disclosure relates to contact grids for use in photovoltaic cells, wherein a cross-section of the contact grid fingers is shaped as a trapezoid, as well as a method of making photovoltaic cells comprising these contact grids. The contact grids of the instant disclosure are cost effective and, due to their thick metal grids, exhibit minimum resistance. Despite having thick metal grids, the unique shape of the contact grid fingers of the instant disclosure allow the photovoltaic cells in which they are employed to retain more solar energy than traditional solar cells by reflecting incoming solar energy back onto the surface of the solar cell instead of reflecting this energy away from the cell.

  • Publication number: 20150325716
    Abstract: Photovoltaic devices are formed with electroplated metal grids that are effectively adhered to the devices. Metal-rich silicides, such as nickel silicides, are formed on the devices by annealing. The metal used in the anneal exhibits low stress. Annealing may be conducted in ambient air followed by removal of oxide and excess metal from the metal-rich silicide. Laser patterning of the antireflective coating of the devices can be used to expose the emitter to form front grid contacts. Doping of the emitter in the patterned region can be increased during laser patterning. The ratio of the centerline to centerline pitch per laser width is controlled to ensure sufficient adhesion of subsequently plated busbars.

  • Patent number: 8878259
    Abstract: Segmented semiconductor nanowires are manufactured by removal of material from a layered structure of two or more semiconductor materials in the absence of a template. The removal takes place at some locations on the surface of the layered structure and continues preferentially along the direction of a crystallographic axis, such that nanowires with a segmented structure remain at locations where little or no removal occurs. The interface between different segments can be perpendicular to or at angle with the longitudinal direction of the nanowire.

  • Patent number: 8865502
    Abstract: The present disclosure provides a method of forming a back side surface field of a solar cell without utilizing screen printing. The method includes first forming a p-type dopant layer directly on the back side surface of the semiconductor substrate that includes a p/n junction utilizing an electrodeposition method. The p/n junction is defined as the interface that is formed between an n-type semiconductor portion of the substrate and an underlying p-type semiconductor portion of the substrate. The plated structure is then annealed to from a P++ back side surface field layer directly on the back side surface of the semiconductor substrate. Optionally, a metallic film can be electrodeposited on an exposed surface of the P++ back side surface layer.
