  • Multijunction organic photovoltaics incorporating solution and vacuum deposited active layers
    Patent number: 11744089
    Abstract: There is disclosed an organic photovoltaic device comprising at least one first subcell comprising at least one first small molecular weight material deposited by solution processing, and at least one second subcell comprising a weight at least one second small molecular material deposited by vacuum evaporation. Also disclosed herein is a method for preparing an organic photovoltaic device comprising at least one first subcell comprising at least one first small molecular weight material and at least one second subcell comprising at least one second small molecular weight material, the method comprising depositing at least one first small weight material by solution processing; and depositing at least one second small weight material by vacuum evaporation.
    Type: Grant

    Date of Patent: August 29, 2023
    Assignee: The Regents of the University of Michigan
    Inventors: Stephen R. Forrest, Brian Lassiter
  • Organic optoelectronics with electrode buffer layers
    Patent number: 10297775
    Abstract: There is disclosed an organic optoelectronic device comprising two electrodes in superposed relation comprising an anode and a cathode, at least one donor material and at least one acceptor material located between the two electrodes forming a donor-acceptor heterojunction, an anode buffer layer adjacent to the anode and a cathode buffer layer adjacent to the cathode, and an intermediate layer adjacent to at least one of the anode and cathode buffer layers, wherein when the intermediate layer is adjacent to the anode buffer layer, the intermediate layer is chosen to facilitate the transport of holes to the anode buffer layer, and when the intermediate layer is adjacent to the cathode buffer layer, the intermediate layer is chosen to facilitate the transport of electrons to the cathode buffer layer. Also disclosed are methods of making the same.
