  • Photoluminescent semiconductor nanocrystal-based luminescent solar concentrators
    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
