Abstract

In various embodiments, an optoelectronic component is provided. The optoelectronic component may include a first electrode having a first electrically conductive substance, a second electrode having a second electrically conductive substance, and at least one active substance. The active substance is formed within a current path of the first electrode and/or the second electrode, and the active substance is set up to convert the first electrically conductive substance and/or the second electrically conductive substance to an electrically nonconductive substance or region.

First claim

The invention claimed is:

1. An optoelectronic component comprising:
a first electrode having a first electrically conductive substance,
a second electrode having a second electrically conductive substance, and
at least one chemically active substance, and nanoparticles, wherein the nanoparticles have a core and a shell, wherein the core is surrounded by the shell, wherein the core includes or is formed from the chemically active substance,
wherein the chemically active substance is formed within a current path of the first electrode and/or the second electrode; and
wherein the chemically active substance is set up to convert the first electrically conductive substance and/or the second electrically conductive substance to an electrically nonconductive substance or region.

2. The optoelectronic component as claimed in claim 1 , wherein the chemically active substance is an oxidizing agent.

3. The optoelectronic component as claimed in claim 1 , wherein the shell is set up to shield the chemically active substance from a chemical reaction.

4. The optoelectronic component as claimed in claim 1 , wherein the shell includes a physically active substance.

5. The optoelectronic component as claimed in claim 1 ,
wherein the chemically active substance is set up so as to be activatable, in such a way that the first electrically conductive substance and/or the second electrically conductive substance can be converted after activation of the chemically active substance.

6. The optoelectronic component as claimed in claim 1 ,
wherein the chemically active substance is distributed in the first electrode and/or the second electrode such that the first electrode and/or the second electrode include(s) the chemically active substance.

7. The optoelectronic component as claimed in claim 1 ,
wherein the optoelectronic component takes the form of a light-emitting diode, a photodetector and/or a solar cell.

8. A method of producing an optoelectronic component, the method comprising:
forming a first electrode having a first electrically conductive substance,
forming a second electrode having a second electrically conductive substance, the second electrode being formed above the first electrode;
forming at least one chemically active substance, and forming nanoparticles, wherein the nanoparticles have a core and a shell, wherein the core is surrounded by the shell, wherein the core includes or is formed from the chemically active substance,
wherein the chemically active substance is formed within a current path of the first electrode and/or the second electrode; and
wherein the chemically active substance is set up to convert the first electrically conductive substance and/or the second electrically conductive substance to an electrically nonconductive substance or region.

9. A method of operating an optoelectronic component, wherein the optoelectronic component comprises:
a first electrode having a first electrically conductive substance,
a second electrode having a second electrically conductive substance, and
at least one chemically active substance, and
nanoparticles, wherein the nanoparticles have a core and a shell, wherein the core is surrounded by the shell, wherein the core includes or is formed from the chemically active substance,
wherein the chemically active substance is formed within a current path of the first electrode and/or the second electrode; and
wherein the chemically active substance is set up to convert the first electrically conductive substance and/or the second electrically conductive substance to an electrically nonconductive substance or region;

including the method comprising:
activating the chemically active substance in such a way that the at least one chemically active substance converts an electrically conductive substance in the current path of the first electrode and/or the second electrode to an electrically nonconductive substance or region.

10. The method as claimed in claim 9 ,
wherein the activation includes application of an overvoltage to the optoelectronic component.

11. The method as claimed in claim 9 ,
wherein the activation includes irradiation of the chemically active substance.

12. The method as claimed in claim 11 ,
wherein the irradiation of the chemically active substance is effected in a structured manner.
