Definitions
- the invention relates to an optoelectronic component having at least one optically functional layer structure and to a method for producing such a layer
- Optoelectronic components which emit light can be, for example, light-emitting diodes (LEDs) or organic ones
- An OLED may have an anode and a cathode with an organic functional layer system therebetween.
- the organic functional may be light emitting diodes (OLEDs).
- Layer system may include one or more
- Emitter layers in which electromagnetic radiation is generated a charge carrier pair generation layer structure of two or more
- CGL Charge pair generation charge generating layer
- HT hole transport layer
- E electron transport layer
- the organic functional layer system requires a protective layer due to its moisture sensitivity
- This protective layer usually makes it difficult to provide a mechanically stable and electrically well-conducting connection of the optoelectronic component to a system in which the optoelectronic component is operated.
- organic light emitting diodes organic light emitting diodes
- organic light emitting diodes organic light emitting diodes
- Solar cells or organic sensors need one preferably mechanically stable and electrically good conducting external connection.
- LEDs and / or OLEDs are often combined together to form an optoelectronic assembly and operated together. It is advantageous to do this
- Contact surfaces usually occupy surfaces in the edge region of the optoelectronic component.
- the thin film encapsulation which is generally deposited over the whole area, is removed by laser ablation, for example.
- solderable contacts are formed by, for example, ACF bonding, (US) soldering, (US) welding or gluing, for example, a flexible circuit board, a metal strip or a cable.
- ACF bonding for example, ACF bonding, (US) soldering, (US) welding or gluing, for example, a flexible circuit board, a metal strip or a cable.
- this forms disadvantageous an additional interface, which increases the contact resistance of the optoelectronic component and so can adversely reduce the efficiency of the optoelectronic device.
- optoelectronic components is not disadvantageous possible. Electro-optical failures of the optoelectronic components are thereby further processed undetected after their production, which disadvantageously additional
- the contact surfaces conventionally used for the external electrical connection proportionally reduce an active area of the optoelectronic components and disadvantageously prevent a rimless arrangement of a plurality of optoelectronic components laterally side by side to form an optoelectronic assembly.
- Component is to be understood in particular the range which is suitable and / or intended for radiation emission and / or radiation detection.
- the object of the invention is to specify an optoelectronic component which has the highest possible efficiency and / or which has a high mechanical stability and / or which is characterized in particular by the highest possible proportion of the active region on the total surface of the optoelectronic component, and / or, in particular, allows a borderless arrangement of a plurality of optoelectronic components side by side.
- a further object of the invention is to provide a method for producing an optoelectronic component which can be carried out simply and / or inexpensively, and / or which in particular is premature in the production sequence
- an optoelectronic component having a first electrically conductive contact layer, an electrical
- the electrically insulating layer over the electrically insulating layer, a first electrically conductive electrode layer over the second electrically conductive contact layer, at least one optically functional layer structure over the first electrically conductive electrode layer and a second electrically conductive electrode layer over the optically functional layer structure.
- the second electrically conductive contact layer has a first recess.
- the electrically insulating layer has a second one
- an electrically conductive via is arranged, which is guided to the first electrically conductive contact layer.
- the electrically conductive via is electrically insulated from the second electrically conductive contact layer.
- the optoelectronic component accordingly has a layer stack with superimposed layers in its construction.
