摘要： 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.

摘要： Methods for patterning a metal over a substrate and devices formed using the methods are disclosed. A patterned die having at least one raised portion and having a metal layer over the die is pressed onto a thin metal film over a substrate, such that the metal layer over the raised portion of the patterned die contacts portions of the thin metal film. Pressure is then applied such that the metal layer and the thin metal film cold-weld to one another. The patterned die is removed, such that the portions of the metal layer cold-welded to the thin metal film break away from the die and remain cold-welded to the thin metal film over the substrate, in substantially the same pattern as the patterned die.

摘要： An organic photovoltaic cell includes an anode and a cathode, and a plurality of organic semiconductor layers between the anode and the cathode. At least one of the anode and the cathode is transparent. Each two adjacent layers of the plurality of organic semiconductor layers are in direct contact. The plurality of organic semiconductor layers includes an intermediate layer consisting essentially of a photoconductive material, and two sets of at least three layers. A first set of at least three layers is between the intermediate layer and the anode. Each layer of the first set consists essentially of a different organic semiconductor material having a higher LUMO and a higher HOMO, relative to the material of an adjacent layer of the plurality of organic semiconductor layers closer to the cathode. A second set of at least three layers is between the intermediate layer and the cathode. Each layer of the second set consists essentially of a different organic semiconductor material having a lower LUMO and a lower HOMO, relative to the material of an adjacent layer of the plurality of organic semiconductor layers closer to the anode.
