  • Patent number: 10317602
    Abstract: The present disclosure describes luminescent solar concentrators that include photoluminescent nanoparticles. The photoluminescent nanoparticles include a semiconductor nanocrystal that sensitizes the luminescence of a defect. The defect can include, for example, an atom, a cluster of atoms, or a lattice vacancy. The defect can be incorporated into the semiconductor nanocrystal, adsorbed onto, or otherwise associated with the surface of the semiconductor nanocrystal.
    Type: Grant
    Filed: April 12, 2018
    Date of Patent: June 11, 2019
    Assignees: Western Washington University, University of Washington Through Its Center For Commercialization
    Inventors: David Patrick, John Gilbertson, Stephen McDowall, Christian Erickson, Daniel R. Gamelin, Liam Bradshaw, Emily Jane McLaurin, Kathryn E. Knowles

  • Publication number: 20110253198
    Abstract: Luminescent solar concentrator (LSC) devices are provided herein. The provided LSCs include devices having an oriented luminophore in at least one layer of the LSC device. Other LSC devices include LSCs having both a collector wave guide, incorporating a luminophore, and a transport wave guide, having no luminophore, into which luminesced light from the collector wave guide travels. Additionally, wave guides for use in LSCs are provided that include guided-wave plasmon-polariton modes for improved optical transmission within LSC devices. The devices provided herein, either alone, or in combination, provide improved LSC device performance, particularly with regard to overall device efficiency.
