    Abstract: Disclosed is a device comprising: an anode; a cathode; an inorganic substrate; and at least one organic window layer positioned between: the anode and the inorganic substrate; or the cathode and the inorganic substrate. Also disclosed is a method of enhancing the performance of a photosensitive device having an anode, a cathode, and an inorganic substrate, comprising: positioning at least one organic window layer between the anode and the cathode. In one embodiment the organic window layer may absorb light and generate excitons that migrate to the inorganic where they convert to photocurrent, thereby increasing the efficiency of the device. Also disclosed is a method of enhancing Schottky barrier height of a photosensitive device, the method being substantially similar to the previously defined method.
