Patents by Inventor Andreas P. Meisel

Andreas P. Meisel 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).

  • Nanostructure and nanocomposite based compositions and photovoltaic devices
    Patent number: 7750235
    Abstract: Nanocomposite photovoltaic devices are provided that generally include semiconductor nanocrystals as at least a portion of a photoactive layer. Photovoltaic devices and other layered devices that comprise core-shell nanostructures and/or two populations of nanostructures, where the nanostructures are not necessarily part of a nanocomposite, are also features of the invention. Varied architectures for such devices are also provided including flexible and rigid architectures, planar and non-planar architectures and the like, as are systems incorporating such devices, and methods and systems for fabricating such devices. Compositions comprising two populations of nanostructures of different materials are also a feature of the invention.
    Type: Grant
    Filed: August 4, 2006
    Date of Patent: July 6, 2010
    Assignee: Nanosys, Inc.
    Inventors: Erik C. Scher, Mihai Buretea, Calvin Y. H. Chow, Stephen A. Empedocles, Andreas P. Meisel, J. Wallace Parce
  • Methods of processing nanocrystals, and compositions, devices and systems including same
    Patent number: 7731932
    Abstract: Methods of processing nanocrystals to remove excess free and bound organic material and particularly surfactants used during the synthesis process, and resulting nanocrystal compositions, devices and systems that are physically, electrically and chemically integratable into an end application.
    Type: Grant
    Filed: August 4, 2008
    Date of Patent: June 8, 2010
    Assignee: Nanosys, Inc.
    Inventors: Erik C. Scher, Mihai A. Buretea, Jeffery A. Whiteford, Andreas P. Meisel
  • Photoactive Devices and Components with Enhanced Efficiency
    Publication number: 20100001982
    Abstract: Devices, compositions and methods for producing photoactive devices, systems and compositions that have improved conversion efficiencies relative to previously described devices, systems and compositions. This improved efficiency is generally obtained by one or both of improving the efficiency of light absorption into the photoactive component, and improving the efficiency of energy extraction from that active component.
