    Abstract: A device is provided having a first electrode, a second electrode, a first photoactive region having a characteristic absorption wavelength λ1 and a second photoactive region having a characteristic absorption wavelength λ2. The photoactive regions are disposed between the first and second electrodes, and further positioned on the same side of a reflective layer, such that the first photoactive region is closer to the reflective layer than the second photoactive region. The materials comprising the photoactive regions may be selected such that λ1 is at least about 10% different from λ2. The device may further comprise an exciton blocking layer disposed adjacent to and in direct contact with the organic acceptor material of each photoactive region, wherein the LUMO of each exciton blocking layer other than that closest to the cathode is not more than about 0.3 eV greater than the LUMO of the acceptor material.

    Abstract: An organic photosensitive optoelectronic device is formed in which the organic photoconductive materials are encapsulated by an electrode of the device. A first transparent film is provided that comprises a first electrically conductive material, arranged on a transparent substrate. A first photoconductive organic material is deposited over the first electrically conductive material. A metal is deposited at an initial rate of no more than 1 nm/s over the first photoconductive organic material, completely covering any exposed portions of the first photoconductive organic material and any exposed interfaces with the first photoconductive organic material to a thickness of no less than 10 nm. After the thickness of no less than 10 nm is obtained, the metal is sputtered at an increased rate at least three times the initial rate until a cumulative thickness of the metal completely covering the previously exposed portions of the first photoconductive organic material and the previously exposed interfaces with the first conductive organic material is at least 250 nm.
