Abstract
An optoelectronic device is provided which comprises an organic active layer (5) provided for generating electromagnetic radiation and a first electrode (1) provided for electrical contacting of the active layer, wherein the first electrode comprises a first electrode layer (11) and a first connection layer (12) spaced at least in places from the first electrode layer, the active layer is arranged at least in places between the first electrode layer and the first connection layer, and the first electrode comprises at least one through via (13) which extends through the active layer and, in so doing, forms an electrical contact between the first electrode layer and the first connection layer. A method for producing such a device is furthermore provided.

An optoelectronic device with an organic active layer provided for generating electromagnetic radiation and a first electrode provided for electrical contacting of the active layer, wherein:
- the first electrode comprises a first electrode layer and a first connection layer spaced at least in places from the first electrode layer;
- the active layer is arranged at least in places between the first electrode layer and the first connection layer;
- and
- the first electrode comprises at least one through via which extends through the active layer and forms an electrical contact between the first electrode layer and the first connection layer.
A method for producing an optoelectronic device comprising the steps of:
- A) providing a carrier body;
- B) applying a first electrode layer onto the carrier body;
- C) forming an organic active layer with at least one cutout on the first electrode layer, wherein the cutout extends through the active layer;
- D) forming at least one through via at least in places in the cutout, such that the through via adjoins the first electrode layer;
- and
- E) forming a first connection layer on a side of the active layer remote from the carrier body, such that, when the device is in operation, the first connection layer is conductively connected by means of the through via with the first electrode layer.
An optoelectronic device with an organic active layer provided for generating electromagnetic radiation, a first electrode provided for electrical contacting of the active layer and a second electrode provided for electrical contacting of the active layer, wherein:
- the second electrode has a second electrode layer;
- the first electrode comprises a first electrode layer and a first connection layer spaced at least in places from the first electrode layer;
- the active layer is arranged at least in places between the first electrode layer and the first connection layer;
- the first electrode comprises a plurality of through vias which extend through the active layer and form an electrical contact between the first electrode layer and the first connection layer;
- and
- the through vias adjoin one another at least in places, such that the through vias form a contiguous through via structure, wherein the contiguous through via structure subdivides the second electrode layer into a plurality of sub-regions which are spaced from one another and wherein the contiguous through via structure subdivides the active layer into a plurality of regions which are separate from one another.
