Thomas A. Lada, II 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).

  • Organic photovoltaic devices comprising fullerenes and derivatives thereof
    Patent number: 8894887
    Abstract: Photovoltaic cells comprising an active layer comprising, as p-type material, conjugated polymers such as polythiophene and regioregular polythiophene, and as n-type material at least one fullerene derivative. The fullerene derivative can be C60, C70, or C84. The fullerene also can be functionalized with indene groups. Improved efficiency can be achieved.
    Type: Grant
    Filed: April 10, 2013
    Date of Patent: November 25, 2014
    Assignees: Solvay USA, Inc., Nano-C, Inc.
    Inventors: Darin W. Laird, Reza Stegamat, Henning Richter, Victor Vejins, Lawrence T. Scott, Thomas A. Lada, II

  • Organic photovoltaic devices comprising fullerenes and derivatives thereof and improved methods of making fullerene derivatives
    Patent number: 8715606
    Abstract: Improved methods of fullerene derivative production including use of less solvent, or elimination of solvent, as well as use of shorter reaction times and higher reaction temperatures. Methods useful for production of bis-, tris-, tetra-, penta-, and hexa-fullerene derivatives. Indene is a preferred derivative. The derivatives used in active layers for solar cell applications.
