  • Organic Light Emitting Component, and Production Method
    Publication number: 20090309492
    Abstract: The invention relates to an organic light emitting component, particularly an organic light emitting diode, in which an arrangement is formed that comprises a bottom electrode, a top electrode, and an organic layer region which is located between and is in electrical contact with the bottom electrode and the top electrode and contains at least one hole transport layer, at least one electron transport layer, and a light-emitting area. The bottom electrode is formed from a dispersion as a structured, binder-free, and optically transparent bottom electrode layer made of a bottom electrode material by means of a wet chemical application process, said bottom electrode material being an optically transparent, electrically conductive oxide. The bottom electrode layer has a sheet resistance of less than about 500 ?/square and an optical refractive index of less than 1.8.
