Abstract
A method for producing high efficiency organic light emitting devices, that have an organic semiconductor active layer sandwiched between electrodes where at least one of the electrodes is a film of conductive nanowires, carbon nanoparticles, light scattering nanoparticles and a polymer support. The light scattering nanoparticles can be incorporated in the conductive nanowires, carbon nanoparticle or polymer support elements of the electrode. The second electrode can be identical to the first to provide a symmetrical device or can be a conductive paste or metal layer. The entire process, including the formation of both of the electrodes, the emissive polymer layer, and the substrate, may be carried out by solution processing.
