Optoelectronic device and method for producing an optoelectronic device

A method for producing an optoelectronic device, the method comprising:

• forming a first organic functional layer structure;
• forming a charge generating layer structure above or on the first organic functional layer structure;
• and
• forming a second organic functional layer structure above or on the charge generating layer structure, wherein forming the charge generating layer structure comprises:
• forming a second electron-conducting charge generating layer;
• forming an interlayer above or on the 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;
• and
• forming a first electron-conducting charge generating layer above or on the interlayer, wherein the first electron-conducting charge generating layer comprises or is formed from an intrinsically electron-conducting substance.
