Lassiter, Brian; Zimmerman, Jeramy D.; Forrest, Stephen R.

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.
