Abstract

An optoelectronic device, comprising: a first organic functional layer structure; a second organic functional layer structure; and a charge generating layer structure between the first organic functional layer structure and the second organic functional layer structure, wherein the charge generating layer structure comprises: a first electron-conducting charge generating layer; wherein the first electron-conducting charge generating layer comprises or is formed from an intrinsically electron-conducting substance; a second electron-conducting charge generating layer; and an interlayer between first electron-conducting charge generating layer; and second electron-conducting charge generating layer; and wherein the interlayer comprises at least one phthalocyanine derivative.
