  • Exciton management in organic photovoltaic multi-donor energy cascades
    Patent number: 10978654
    Abstract: Disclosed herein are organic photosensitive optoelectronic devices, such as organic photovoltaics, including a photoactive region, wherein the photoactive region contains an energy-cascading multilayer donor region. The energy-cascading multilayer donor region may drive exciton transfer from an anode to a dissociating interface while reducing exciton quenching, improving overlap with the solar spectrum, and minimizing polaron pair recombination, resulting in improved device performance.
    Type: Grant
    Filed: October 27, 2014
    Date of Patent: April 13, 2021
    Assignee: The Regents of the University of Michigan
    Inventors: Stephen R. Forrest, Olga L Griffith
