ABSTRACT:
A cathode adapted for use in an organic optoelectronic device is provided. The cathode has an electron injection layer, an organic buffer layer, a conducting layer, and a transparent conductive oxide layer disposed, in that order, over the organic operative layers of the optoelectronic device. A method of fabricating the cathode is also provided.
