    Abstract: A highly transparent non-metallic cathode is disclosed that comprises a metal-doped organic electron injection layer that is in direct contact with a transparent non-metallic electron injecting cathode layer, such as indium tin oxide (ITO), wherein the metal-doped organic electron injection layer also functions as an exciton blocking or hole blocking layer. The metal-doped organic electron injection layer is created by diffusing an ultra-thin layer of about 5-10 Å of a highly electropositive metal such as Li throughout the layer. A representative embodiment of the highly transparent non-metallic cathode comprises a layer of ITO, a layer of 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP), which acts as an electron injection, exciton blocking, and hole blocking layer, and an ultra-thin layer of lithium, which degenerately dopes the layer of BCP, improving the electron injecting properties of the BCP layer. This cathode is demonstrated for use in an OLED having a transparency of about 90% or higher combined with a device external quantum efficiency of about 1% or higher.

    Abstract: The present invention relates to patterning methods for organic devices, and more particularly to patterning methods using a die. A first layer of organic materials is deposited over a substrate, followed by a first electrode layer. A first patterned die having a raised portion is then pressed onto the first electrode layer, such that the raised portion of the first patterned die contacts portions of the first electrode layer. The patterned die is removed, such that the portions of the first electrode layer in contact with the raised portions of the first patterned die are removed. In one embodiment of the invention, a second organic layer is then deposited over the first electrode layer, followed by a second electrode layer. A second patterned die having a raised portion is pressed onto the second electrode layer, such that the raised portion of the second patterned die contacts portions of the second electrode layer. The second patterned die is removed, such that the portions of the second electrode layer in contact with the raised portions of the second patterned die are removed. Preferably the patterned die is coated with an adhesive material such as a metal.

    Abstract: A stacked organic photosensitive optoelectronic device optimized to enhance desired characteristics such as external quantum efficiency and current. The photosensitive optoelectronic device has a plurality of photosensitive optoelectronic subcells electrically configured in parallel. The substrate may be the bottom electrode or there may be a bottom electrode distinct from the substrate. Each subcell comprises one or more organic photoconductive layers between electrode layers. The thicknesses of the subcells and the total number of subcells may be selected, for example, so as to maximize the external quantum efficiency of a stacked solar cell. In one embodiment the top electrode is transparent. In other embodiments two or more electrodes are transparent. In other embodiments photosensitive optoelectronic devices with multilayer photoconductive structures and photosensitive optoelectronic devices with a reflective layer or a reflective substrate are disclosed.
