Abstract

Large, light-weight organic devices and methods of preparing large, light-weight organic devices. Specifically, flexible and rigid light-weight plastics are implemented. The flexible plastic may be disposed from a reel. A metal grid is fabricated on the flexible plastic to provide current conduction over the large area. A transparent oxide layer is provided over the metal grid to form the bottom electrode of the organic device. A light emitting or light gathering organic layer is disposed on the transparent oxide layer. A second electrode is disposed over the organic layer. Electrodes are coupled to the metal grid and the second electrode to provide electrical current to or from the organic layer. Depending on the type of materials used for the organic layer, the organic device may comprise an area light device or a photovoltaic device.
