Abstract: Optoelectronic device comprising an organic active layer provided for generating electromagnetic radiation, and first and second electrodes contacting the active layer. 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, with the active layer being arranged at least in places therebetween, and through vias extend through the active layer and form an electrical contact between the first electrode layer and the first connection layer. The through vias form a contiguous through via structure that 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. In operation, the through vias are electrically conductively connected to one another directly.

Abstract: A method of producing an organic optoelectronic component includes: forming a first electrode layer comprising a contact region, arranging an electrically conductive contact lug on the first electrode layer. A first section of the contact lug is secured in the contact region on the first electrode layer such that a second section projects beyond the contact region. The method further includes forming an organic functional layer structure laterally alongside the contact lug on the first electrode layer, forming a second electrode on the organic functional layer structure, forming an encapsulation layer such that it extends over the second electrode and over the first section, and severing the first electrode layer and the encapsulation layer in the region of the lug such that subsequently the first section is arranged between the contact region and the encapsulation layer and the second section projects between the encapsulation layer and the first electrode layer.
