Abstract

An organic opto-electrical device comprising: a substrate having a first electrode disposed thereon for injecting charge carriers of a first polarity; an organic semiconductive region disposed over the first electrode; and a transparent second electrode disposed over the organic semiconductive region for injecting charge carriers of a second polarity, wherein the second electrode comprises a charge injecting layer, a buffer layer disposed over the charge injecting layer, and a transparent conductive layer disposed over the buffer layer, the buffer layer comprising an inorganic metal oxide material.
