Optoelectronic device comprising an active organic layer with improved performance and method for producing said device

A method of manufacturing an optoelectronic device, comprising the successive steps of:

• a) forming on a support first and second electrically-conductive pads;
• b) depositing an active organic layer covering the first and second electrically-conductive pads;
• c) depositing a first interface layer on the active organic layer in contact with the active organic layer;
• d) forming a first opening in the first interface layer and a second opening in the active organic layer in line with the first opening, to expose the second electrically-conductive pad;
• and
• e) forming a second interface layer extending at least partly in the first and second openings, the second interface layer in contact with the first interface layer and with the second electrically-conductive pad,
• wherein the first interface layer and/or the second interface layer comprise at least one compound selected from the group comprising a host/molecular dopant system, a conductive or doped semiconductor polymer, a carbonate, a polyelectrolyte, and a mixture of two or more of these materials.
