Definitions
- metals with small work functions are used for n-type contacts of optoelectronically active areas of components. This relationship is described, for example, in Brabec C.J., Sariciftci N. and Hummelen J.: "Plastic Solar Cells", Advanced Functional Materials, 2001, 11, no. 1, pages 15 to 26.
- metals with a small work function are generally difficult to process and unstable in air.
- Field effect electrodes are known from DE 26 32 895 AI and DE 198 22 501 AI.
- the object of the invention is to provide an improved n-type contact for, in particular organic, optoelectronic components.
- a component with an optoelectronically active region has means for generating a field effect in the optoelectronically active region in order to influence the removal and / or supply of charge carriers from and / or into the optoelectronically active region.
- a field effect contact is used as the negative electrode for the component.
- the component advantageously has a contact area, in particular a layered electrode, for contacting the optically active area.
- a contact area in particular a layered electrode, for contacting the optically active area.
- Contact areas for contacting the optical area can be used to remove charge carriers, that is to say electrons or holes, from the optically active area or to supply them to the optically active area.
- An ohmic contact for the charge carriers can preferably be generated by the means for generating a field effect between the contact area for contacting the optoelectronically active area and the optoelectronically active area.
- the optoelectronically active region can be formed by a semiconductor, in particular an organic semiconductor.
- the contact area for contacting the optoelectronically active area preferably consists of metal, in particular aluminum, silver and / or gold.
- the means for generating a field effect preferably have an electrode that functions as a field effect electrode, in particular a metal electrode.
- the means for generating a field effect can also have an insulator, in particular an insulator layer.
- the insulator layer is preferably arranged between the field effect electrode and the optically active region.
- a grating can also be printed in the insulator which, together with the field electrode, forms a light trap.
- the component is in particular a fotovoltaisch.es, light-detecting (photodetector) and / or light-emitting component.
- the means for generating a field effect expediently also have means for applying a voltage between the field effect electrode and the optoelectronically active region in order to produce a field effect in the optoelectronically active region.
- means for generating a field effect are arranged on the component in order to influence the removal and / or supply of charge carriers from and / or into the optoelectronically active region.
- a field effect is generated in the optoelectronically active region by means of generating a field effect.
- Figure 1 shows a component
- a semitransparent or transparent electrode 2 for example made of indium tin oxide (ITO)
- ITO indium tin oxide
- an optoelectronically active region 3 in the form of a photoactive semiconductor layer which consists, for example, of conjugated polymers, organic molecules or mixtures thereof, in particular of a "conjugated polymer filler”. Mixture.
- a field effect electrode in or on the n-type contact (negative electrode) is now proposed.
- any metal for example gold, is deposited in a structured manner as contact region 4 for contacting the optoelectronically active region onto the optoelectronically active region 3.
- the contact area 4 for contacting the optoelectronically active area functions equivalent to the source or drain contacts of a field effect transistor. It can, for example, be printed out of the solution, in particular using silver conductive pastes, or it can also be deposited (evaporated) from the gas phase.
- An insulator 5 is arranged on the contact area 4 for contacting the optoelectronically active area.
- the insulator 5 can for example be printed in the form of polyhydroxystyrene or in the form of SiO 2 or
- AI2O3 evaporated, i.e. thermally separated.
- the insulator 5 is then the actual one
- Field effect electrode 6 deposited another metal electrode, which is equivalent to the gate contact of a field effect transistor.
- the field effect electrode 6 is made of gold, for example.
- these contacts allow a very simple structuring of the component, which has a positive effect on the light coupling out, for example if the component is an organic light-emitting diode (OLED), or for light coupling in, for example if the component is an organic photovoltaic Component (OPV) or an organic photo detector.
- OLED organic light-emitting diode
- OCV organic photovoltaic Component
- a grating can be printed in the insulator 5, which forms a light trap together with the gate electrode, ie the field effect electrode 6.
- the entire contact consisting of the negative electrode, in the form of the contact region 4 for contacting the optoelectronically active region, the insulator 5 and the field effect electrode 6 can advantageously be printed. This enables the production of a completely printed component in the form of a solar cell, light-emitting diode or photodiode.
