Claim Text:
1. 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; wherein the interlayer comprises at least one phthalocyanine derivative; and wherein the interlayer comprises or is formed from the same substance or the same substance mixture as the substance or the substance mixture of the first electron-conducting charge generating layer, wherein however the substance or the substance mixture has a different physical structure, or wherein the interlayer comprises or is formed from the same substance or the same substance mixture as the substance or the substance mixture of the second electron-conducting charge generating layer, wherein however the substance or the substance mixture has a different physical structure.
