A hybrid buffer layer with superior plasma protection ability and high injection efficiency was developed. The hybrid buffer layer composed by dual-layered structure of HATCN/MoO3 enhances hole-injection efficiency and protects organic layers under the top electrode. This hybrid buffer layers improve the electric characteristics of inverted top-emitting organic light- emitting diodes.
