Abstract

An element (1) is provided for stabilising an optoelectronic device (7), wherein the element (1) comprises a main body (1C), wherein the main body (1C) consists of a glass or at least comprises a glass and wherein the main body (1C) comprises a first and a second surface (1A, 1B). The first and second surface (1A, 1B) are opposite to one another and extend in each case in a lateral main direction of extension of the element (1), wherein a protective layer (2A, 2B) is formed at least at one of the surfaces (1A, 1B) and wherein the protective layer (2A, 2B) is configured and arranged in such a way that cracks (3) present in the main body (1C) are filled in by a material of the protective layer (2A, 2B). In addition, an optoelectronic device (7) is provided.

First claim

The invention claimed is:

1. An element for stabilizing an optoelectronic device comprising:
a main body, which consists of a glass or at least comprises a glass, wherein the main body comprises a first and a second surface,
wherein the first and the second surface lie opposite to one another and extend in each case in a lateral main direction of extension of the element,
wherein a protective layer is fored at least at one of the surfaces,
wherein the protective layer is configured and arranged in such a way that cracks present in the main body are at least partly filled in by a material of the protective layer,
wherein the protective layer comprises a metal oxide or a metal nitride, and
wherein a protective film is arranged on the second surface, and the surface of the protective film remote from the main body is covered with a second protective layer.

2. The element according to claim 1 , wherein the main body consists of the glass,
wherein the main body is a homogeneously formed solid body, and
wherein the protective layer directly adjoins the glass.

3. The element according to claim 1 , wherein the main body has a thickness (d) of less than or equal to 500 μm.

4. The element according to claim 1 , wherein the protective layer is light-transmitting.

5. The element according to claim 1 , wherein a first protective layer is formed on the first surface, and
wherein a second protective layer is formed on the second surface.

6. The element according to claim 1 , wherein a first protective layer is formed on the first surface,
and
wherein the protective film comprises a laminated plastics material.

7. The element according to claim 1 , wherein the at least one protective layer at least partly fills in the cracks in the main body,
wherein the protective layer completely covers the first surface and/or the second surface of the main body,
wherein the material of the protective layer extends into the cracks, and
wherein the at least one protective layer is of one-piece construction.

8. The element according to claim 1 , further comprising:
a transparent conductive layer, wherein the transparent conductive layer is arranged on the protective layer, and
wherein the transparent conductive layer comprises an electrically conductive oxide or a thin metal layer.

9. A method for producing an element for stabilizing an optoelectronic device, the element comprising a main body, which consists of a glass or at least comprises a glass,
wherein the main body comprises a first and a second surface,
wherein the first and the second surface lie opposite to one another and extend in each case in a lateral main direction of extension of the element,
wherein a protective layer is formed at least at one of the surfaces, and
wherein the protective layer is configured and arranged in such a way that cracks present in the main body are at least partly filled in by a material of the protective layer,
the method comprising the following steps:
providing the main body; and
applying the protective layer to at least one of the surfaces of the main body,
wherein the protective layer is applied by means of atomic layer deposition.

10. The method according to claim 9 , wherein the protective layer is configured and arranged to prevent spontaneous breaking of the main body and thus to stabilize the main body, and
wherein on application of the protective layer cracks present in the main body are filled in by the material of the protective layer.

11. The method according to claim 9 , wherein a first protective layer is applied to the first surface, and
wherein a second protective layer is applied to the second surface, or firstly a protective film is applied at least temporarily to the second surface and then the protective layer is applied to the first surface.

12. The method according to claim 11 , wherein the protective film comprises a laminated plastics film,
wherein the protective film is configured to prevent damage by scratches to the second surface, and/or
wherein the protective film is configured to prevent wetting of the second surface with the protective layer.

13. The method according to claim 9 , comprising the further step:
applying a transparent conductive layer to the protective layer,
wherein the transparent conductive layer comprises an electrically conductive oxide or a thin metal layer.

14. An optoelectronic device comprising:
at least one functional region, wherein the functional region comprises at least one organic material; and
at least one element for stabilizing an optoelectronic device having a main body, which consists of a glass or at least comprises a glass,
wherein the main body comprises a first and a second surface,
wherein the first and the second surface lie opposite to one another and extend in each case in a lateral main direction of extension of the element,
wherein a protective layer is formed at least at one of the surfaces,
wherein the protective layer is configured and arranged in such a way that cracks present in the main body are at least partly filled in by a material of the protective layer, and
wherein the functional region is arranged on the element.

15. The optoelectronic device according to claim 14 , comprising:
a second element for stabilizing an optoelectronic device, the second element comprising a main body, which consists of a glass or at least comprises a glass,
wherein the main body comprises a first and a second surface,
wherein the first and the second surface lie opposite to one another and extend in each case in a lateral main direction of extension of the second element,
wherein a protective layer is formed at least at one of the surfaces,
wherein the protective layer is configured and arranged in such a way that cracks present in the main body are at least partly filled in by a material of the protective layer,
wherein the second element is arranged on a surface of the functional region remote from the element.

16. The optoelectronic device according to claim 14 , wherein the device is flexible, and
wherein the at least one functional region comprises at least one of the following components:
an organic light-emitting cell,
an organic solar cell,
an organic light-emitting diode, or
an organic photodiode.

17. The method according to claim 9 , wherein a first protective layer is formed on the first surface,
wherein a protective film is arranged on the second surface,
wherein the protective film comprises a laminated plastics material, and
wherein the surface of the protective film remote from the main body is covered with a second protective layer.
