  • Flexible electronic display device
    Patent number: 11832475
    Abstract: A method of fabricating a light emitting device comprises providing a mold having an unpolished surface with an arithmetic mean roughness Ra in a range from 0.1 ?m to 10 ?m, depositing a thin polymer film over the surface of the mold, wherein the film has a thickness in a range from 1 ?m to 100 ?m, positioning a light emitting body onto the thin polymer film, wherein the light emitting body includes an anode, a cathode, and a light emitting layer positioned between the anode and the cathode, and separating the thin polymer film with the light emitting body from the mold. A light emitting device is also described.
    Type: Grant
    Filed: May 27, 2022
    Date of Patent: November 28, 2023
    Assignee: The Regents of the University of Michigan

  • Key materials for organic photovoltaics reliability
    Patent number: 11594686
    Abstract: Organic photovoltaic cells (OPVs) and their compositions are described herein. one or more embodiments, the acceptor with an active layer of an OPV includes is a non-fullerene acceptor. Such non-fullerene acceptors may provide improved OPV performance characteristics such as improved power conversion efficiency, open circuit voltage, fill factor, short circuit current, and/or external quantum efficiency.
