A method for making an electrode over a light emissive layer in an organic light emitting device includes providing the organic light emitting device into a vacuum chamber having a receptacle for vaporizing material. Heating the receptacle to evaporate material placed in the receptacle for deposition onto the light emissive layer to form the electrode, and a shutter, which when open, permits evaporated material from the heated receptacle to deposit onto the light emissive layer. The method also includes selectively feeding an elongated member made of material to be evaporated into the heated receptacle when the electrode is to be formed and removing such material from such heated receptacle when such electrode is not to be formed.
