1. An organic photosensitive optoelectronic device comprising:

  • an organic photodetector comprised of;

    two electrodes in superposed relation;

    a hole transport layer between the two electrodes, the hole transport layer formed of a first photoconductive organic semiconductor material;

    an electron transport layer between the two electrodes and adjacent to the hole transport layer, the electron transport layer formed of a second photoconductive organic semiconductor material; and

    at least one exciton blocking layer between the two electrodes and adjacent to at least one of the two electrodes.
