Vladimir M. Fridkin 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).

  • Photovoltaic cells comprising a layer of crystalline non-centrosymmetric light-absorbing material and a plurality of electrodes to collect ballistic carriers
    Patent number: 10903378
    Abstract: The present invention is directed to photovoltaic and photogalvanic devices and methods of generating electrical energy and power or detecting light therefrom, based on a novel nano-enhanced bulk photovoltaic effect using non-centrosymmetric crystals, including ferroelectric and piezoelectric materials, where the non-centrosymmetry is the equilibrium state or it is static or dynamically induced. In certain embodiments, the device comprises a layer of non-centrosymmetric crystalline materials, and a plurality of electrodes disposed in an array upon or penetrating into at least one surface of the crystalline material, the electrodes being optimally spaced to capture the ballistic carriers generated upon irradiation of the crystalline material.
    Type: Grant
    Filed: July 30, 2018
    Date of Patent: January 26, 2021
    Assignees: Drexel University, The Trustees of the University of Pennsylvania
    Inventors: Jonathan E. Spanier, Vladimir M. Fridkin, Alessia Polemi, Andrew M. Rappe
