Patents by Inventor Brett Caroline Baker-O'Neal

Brett Caroline Baker-O'Neal has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10199516
    Abstract: Photovoltaic devices are formed by laser drilling vias through silicon substrates and, following surface preparation of the via sidewalls, plating a continuous, electrically conductive layer on the via sidewalls to electrically connect the emitter side of the cell with the back side of the cell. The electrically conductive layer can be formed on portions of a base emitter within the vias and on the back side of the substrate. Alternatively, the electrically conductive layer can be formed on a passivation layer on the via sidewalls and back side of the cell.
    Type: Grant
    Filed: July 8, 2017
    Date of Patent: February 5, 2019
    Assignee: International Business Machines Corporation

  • 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.
