Abstract

An optoelectronic component may include an electrically active region and a light-refracting structure which includes at least one graphene layer, in which at least one lens-like structure is formed. The electrically active region may include a first electrode, a second electrode, and an organic functional layer structure between the first electrode and the second electrode.

Claims (49)

1. An optoelectronic component, comprising:

an electrically active region, comprising:

a first electrode;

a second electrode;

an organic functional layer structure between the first electrode and the second electrode;

a light-refracting structure which comprises at least one graphene layer, in which at least one lens-like structure is formed.

2. The optoelectronic component as claimed in claim 1 ,

wherein the graphene layer forms a part of the first electrode and/or of the second electrode.

3. The optoelectronic component as claimed in claim 2 , further comprising:

a carrier;

wherein the graphene layer is arranged as part of the first electrode on or over the carrier.

4. The optoelectronic component as claimed in claim 2 ,

wherein the second electrode is configured so as to be translucent or reflective.

5. The optoelectronic component as claimed in claim 1 ,

wherein the graphene layer is arranged outside the electrically active region.

6. The optoelectronic component as claimed in claim 3 , further comprising:

a carrier;

wherein the graphene layer is arranged on or over the carrier;

a planarization layer on the graphene layer;

wherein the electrically active region is arranged on or over the planarization layer.

7. The optoelectronic component as claimed in claim 6 , further comprising:

an encapsulation being arranged between the electrically active region and the carrier.

8. The optoelectronic component as claimed in claim 7 ,

wherein the encapsulation is arranged between the electrically active region and the graphene layer or between the electrically active region and the planarization layer, wherein the planarization layer has a refractive index which is substantially equal to the refractive index of the carrier.

9. The optoelectronic component as claimed in claim 6 ,

wherein the first electrode is arranged on or over the planarization layer;

wherein the first electrode is configured so as to be translucent; and

wherein the second electrode is configured so as to be translucent or reflective.

10. The optoelectronic component as claimed in claim 3 ,

wherein the first electrode is configured so as to be reflective; and

wherein the second electrode is configured so as to be translucent;

wherein the graphene layer is arranged on or over the second electrode.

11. The optoelectronic component as claimed in claim 10 , further comprising:

a carrier;

wherein the first electrode is arranged on or over the carrier.

12. The optoelectronic component as claimed in claim 10 , further comprising:

an encapsulation on or over the second electrode.

13. The optoelectronic component as claimed in claim 12 ,

wherein the graphene layer is arranged on or over the encapsulation.

14. The optoelectronic component as claimed in claim 1 ,

wherein the at least one lens-like structure is at least partially filled with a liquid and/or a solid, wherein the liquid and/or the solid preferably has a refractive index which is substantially equal to the refractive index of the organic functional layer structure.

15. The optoelectronic component as claimed in claim 10 , further comprising:

a cover layer on or over the graphene layer, wherein the cover layer has a refractive index which is less than the refractive index of the liquid and/or of the solid.

16. The optoelectronic component as claimed in claim 3 ,

wherein the second electrode is configured so as to be translucent or reflective.

17. The optoelectronic component as claimed in claim 8 ,

wherein the planarization layer has a refractive index which is substantially equal to the refractive index of the organic functional layer structure.

18. The optoelectronic component as claimed in claim 11 , further comprising:

an encapsulation on or over the second electrode.
