Abstract

An organic light-emitting component, having a substrate, a first electrode arranged on the substrate, a layer stack that is arranged on the first electrode and that has at least one organic layer and a second electrode arranged on the layer stack. The layer stack is suitable for emitting electromagnetic radiation during operation. The component also has a receiver device, which is suitable for drawing energy from an alternating electromagnetic field and for converting this energy at least partially into electrical energy and for making this energy available to the layer stack.

an insulating layer that at least partially covers the second electrode; and

a receiver device that draws energy from an alternating electromagnetic field and converts the energy at least partially into electrical energy, and that injects the electrical energy for generating the electromagnetic radiation into the layer stack,

wherein the receiver device comprises a coil, and

wherein the layer stack, the second electrode, the insulating layer and the receiver device are all at least partially stacked on top of each other.

2. The organic light-emitting component of claim 1, wherein the receiver device comprises a plurality of coils forming a spiral having an average diameter decreasing in a direction to a center of the second electrode as seen in a top view.
