Abstract
Official abstract text for this publication.
An optoelectronic device is disclosed. In an embodiment the optoelectronic device includes a light-transmissive first electrode, an electrically conductive track including a metal, and a functional organic region having at least one active region, wherein the electrically conductive track is arranged between the first electrode and the functional organic region and wherein the electrically conductive track is in direct contact with the first electrode and the functional organic region.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing an optoelectronic device, the method comprising: applying a light transmissive first electrode to a carrier; printing an electrically conductive track, which comprises a metal, on a side of the first electrode which faces away from the carrier; and applying a functional organic region, which comprises at least one active region, on a side of the first electrode and the electrically conductive track which faces away from the carrier, wherein the electrically conductive track is in direct contact with the first electrode and the functional organic region; wherein the electrically conductive track is formed by a metallic ink; wherein the metallic ink comprises a dopant for the functional organic region; and wherein the dopant is configured to deactivate another opposite-type dopant present in an adjacent functional organic region such that, in a boundary region between the electrically conductive track and the functional organic region, at least one area that is free from charge carriers or reduced in charge carriers is formed. 2. The method according to claim 1 , wherein the functional organic region is applied to directly adjoin the first electrode. 3. The method according to claim 1 , wherein the electrically conductive track and the functional organic region form a p-n junction, which is in antiparallel connection with the active region of the organic functional region. 4. The method according to claim 1 , wherein the first electrode is formed as a layer having a main extension plane, wherein an area of the main extension plane is at least 90% of an area of a cross-sectional area of the functional organic region, and wherein the cross-sectional area is arranged parallel to the main extension plane. 5. The method according to claim 1 , wherein the first electrode comprises a transparent conductive oxide. 6. The method according to claim 1 , further comprising forming a plurality of electrically conductive tracks. 7. The method according to claim 1 , further comprising forming a second electrode arranged on a side of the functional organic region facing away from the first electrode.
