Hani Khallaf 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).

  • Electrode structure, method and applications
    Patent number: 8735718
    Abstract: An organic photovoltaic cell structure and a method for fabricating the organic photovoltaic cell structure are each predicated upon an organic photovoltaic material layer located and formed interposed between an anode and a cathode. The organic photovoltaic cell structure and the method for fabricating the organic photovoltaic cell structure also include for the anode a nickel and indium doped tin oxide material layer (Ni-ITO) that has a nickel doping sufficient to provide a work function of the nickel and indium doped tin oxide material layer (Ni-ITO) anode preferably no more positive than about ?5.0 eV.
    Type: Grant
    Filed: April 20, 2011
    Date of Patent: May 27, 2014
    Assignee: University of Central Florida
    Inventors: Winston V. Schoenfeld, Hani Khallaf

  • PHOTOVOLTAIC CELL STRUCTURE AND METHOD INCLUDING COMMON CATHODE
    Publication number: 20120060907
    Abstract: A back-to-back parallel tandem organic photovoltaic cell structure and a method for fabricating the back-to-back parallel tandem organic photovoltaic cell structure include an aluminum doped zinc oxide material layer (AZO) as a common central cathode within the back-to-back parallel tandem organic photovoltaic cell structure and sandwiched between (and contacting) a pair of lithium fluoride material layers (LiF). The back-to-back parallel tandem organic photovoltaic cell structure and the related method also includes separate and different active material layers further separated from the aluminum doped zinc oxide material layer (AZO) common central cathode and further separated nickel and indium doped tin oxide material layer (Ni-ITO) anodes. An aluminum doped zinc oxide material layer (AZO) and lithium fluoride material layer (LiF) laminate is also contemplated for use in various photovoltaic cell structures.
