Description

Technical field

The invention relates to a optoelectronic component with electrically conductive organic Material and with at least two spaced apart Strip electrodes that form a pair of strip electrodes and between them at least one layer of the electrically conductive organic material is provided.

Under the name "optoelectronic components" are basically both Solar cells for converting electromagnetic radiation energy to understand in electrical energy, as well as light emitting diodes in the opposite sense electrical into electromagnetic energy, preferably convert it into visible light. Optoelectronic Components of the aforementioned type, which instead of one an electrically photoactive layer consisting of semiconductor material conductive, Organic, preferably polymeric material layers are currently capable not reach those energetic efficiencies that with conventional, exclusively optoelectronic components based on semiconductor materials are achievable, but it is precisely those new types of optoelectronic Components by their extremely cheapest Materials and manufacturing options from which they are increasingly of economic interest.

In 1b A typical layer structure of an organic light-emitting diode (OLED) is shown, which is also representative of a layer sequence of organic photo or solar cells. So there is an active organic layer 1 between two electrode surfaces 2 . 3 which, at least in the case of solar cells, each have different electrical work functions. At least one of the two electrodes is optically transparent and ensures the emission or entry of radiation hv. In the case of the known layer structure according to 1b assume that the optically transparent electrode 3 is applied to an equally light-transparent carrier substrate T. The light-transparent electrode typically consists of a commercially available ITO layer (tin-doped indium oxide), which is preferably applied to a glass substrate T by means of a typical vapor deposition or sputtering process. The photoactive, organic material layer 1 , which consists of polymers such as PPV, poly-para-phenylene-vinylene or polythiophene derivatives as well as fullerene derivatives such as C ₆₀ , is by spin coating or knife coating on the deposited ITO layer 3 applied. Typical layer thicknesses of the organic layer 1 are in the range of 100 nm to a few 100 nm. Ultimately, the counter electrode 2 mostly an aluminum layer on the optically active, organic material layer 1 evaporated.

However, the above layer structure for optoelectronic components has a number of disadvantages: due to only limited charge carrier mobility for holes and electrons within the organic material layer 1 are any layer thickness selection for the layer 1 set technical limits that are only limited to layer thicknesses of a few 100 nm. Larger layer thicknesses would, however, be desirable in view of an improved absorption capacity for solar cell operation.

In addition, due to manufacturing, occur within the ITO layer 3 deposited organic layer 1 Discontinuities, for example in the form of through holes, so-called pinholes, can be found in a metal deposition process for the production of the electrode surface 2 can also be filled with electrically conductive material, which ultimately creates the risk of a short circuit between the electrodes 2 and 3 is increased.

In addition, the required transparent ITO electrode 3 , through which the light enters in the case of the solar cell and the light emission in the case of the light-emitting diode, is a decisive cost factor and moreover limits the variability in the free choice of electrode material with regard to electrical work function.

The invention is based on the object generic optoelectronic Component with electrically conductive organic material and with at least two spaced apart Strip electrodes that form a pair of strip electrodes and between which at least one layer of the electrically conductive organic Material is provided to develop such that the optoelectronic Properties of the optoelectronic component can be improved should. In particular, it is necessary to look for solutions to the cost-intensive ITO layer through cheaper To replace variants, which ultimately also means the degree of freedom for one greater choice of materials for the electrode layers to be created. For the operation of the layer structure described above both as a solar cell and as a light-emitting diode, it applies in both cases optimize energy efficiency and their manufacturing costs to lower. In connection with the desire for lower manufacturing costs It is also important to specify a process technology with which the optoelectronic Components from an economic and industrial point of view can be produced.

The solution to the problem on which the invention is based is specified in claim 1. Ge The subject matter of claim 25 is a method for producing an electronic component according to the invention, which can preferably be used as a solar cell and also as a light-emitting diode.

The basis of the invention Idea prevails the usual so far Radiographic principle in optoelectronic components, after which the radiation direction is always perpendicular to the component layers is oriented and therefore at least one light-transparent electrode, preferably an ITO electrode, is required. In turn, according to the invention, a novel one Construction or a new type of cell architecture for organic photo or solar cells as well as organic light-emitting diodes, which have at least two, preferably a plurality of stacked one above the other, each mutually provides spaced strip electrodes that form pairs of strip electrodes can be grouped, at least between their strip electrodes a layer of the electrically conductive organic material is provided. Characteristic of this new type of electrode structure for a The optoelectronic component is the stacked strip electrode arrangement conditional mode of operation of the component such that the with the electrically conductive, optically active, organic material layer interacting Light parallel to the stripe electrode surfaces within the organic Spreads material layer. This ultimately leads to that light interacting with the organic material layer without providing any intermediate layers over the side edges in the organic trapped between two strip electrode surfaces Enter material layer or can be emitted from this. This opened there are a number of advantages: Despite the material-related relatively small Carrier mobility of suitable organic materials, the layer depth is along the in the case of a solar cell, light absorption within the organic Layer takes place to choose almost any size, especially with the parallel to the strip electrode surfaces directed radiation for the absorption-relevant layer depth not from the electrode distance, but from the electrode length is determined. In contrast, the electrode spacing remains with respect to the Carrier mobility still relevant and typically corresponds to the layer thickness the organic material layer of conventional organic Solar cells.

To be as large as possible, in the case of a solar cell to disposal standing lighting surface made of electrically conductive, Obtaining organic material is a variety according to the invention juxtaposed surface electrode pairs each with organic material in between, the number of which is provided and arrangement basically are freely dimensionable and scalable.

Because the light propagation characteristic the use within the novel optoelectronic component optically transparent electrode layers, especially the use of indium tin oxide (ITO) as a transparent electrode material, makes it superfluous, improve by eliminating this previous requirement automatically the selection options significant for electrode materials, especially with regard to cheap Electrode pair materials with different electrical work functions for the construction of Solar cells.

As in more detail below accomplished is made possible the tent architecture according to the invention a novel manufacturing process, which in particular the risk of short circuit due to existing pinholes within the organic material layer can be completely excluded.

A method according to the invention provides for Production of an optoelectronic component of the above Art in a first step first the manufacture of the stacked arranged strip electrodes in front. Only after completing the Strip electrode arrangement, for their formation metal deposition processes are required, the electrically conductive, organic material in the correspondingly provided free spaces between the pairs of strip electrodes brought in. In this way too, training can be done by itself discontinuities forming within the organic material layer, for example in the form of through openings, not completely can be avoided, but due to procedural reasons it is excluded that any pinholes present within the organic material layer with electrically conductive Subsequent electrode material filled can be especially since the manufacture of the strip electrodes and thus any Metal deposits already in the previous process step Are completed.

Further advantages of the designed according to the invention optoelectronic component and advantageous exemplary embodiments and in particular the description of the manufacture according to the invention of such an optoelectronic component are shown below with reference to the embodiments described.

Ways to Execute the Invention, industrial applicability

In contrast to the known layer structure according to 1b The tent architecture of an optoelectronic component designed according to the invention has a plurality of stacked strip electrodes arranged vertically or next to one another 4 . 5 before, both in contrast to the known embodiment according to 1b consist of electrically conductive materials that are not transparent to solar radiation. This opens up a wide range and selection options for suitable electrode materials, which can be freely selected in terms of their electrical work functions depending on the material combinations. The large number of strip electrodes arranged in a stack 4 . 5 form strip electrode pairs P, their respective associated strip electrodes 4 . 5 electrically conductive, organic material 1 lock in. The organic material 1 fills the through the respective strip electrodes 4 . 5 limited space between a pair of strip electrodes P completely and closes on both sides with the respective boundary edges of the strip electrodes 4 . 5 flush.

Furthermore, the layer structure looks like 1a electrically and optically inactive intermediate layers 6 before, by which two adjacent strip electrode pairs P are separated. The intermediate layers 6 originate from the manufacturing process and preferably consist of the material used as a structured carrier substrate for manufacturing the strip electrode arrangement 4 . 5 serves. This will be discussed in more detail below.

Due to the multiple arrangement of the stacked strip electrode pairs P in the in 1a is a freely accessible transition level 7 created by the light by in the individual organic material layers 1 enters or exits unhindered. This applies to both the upper and the lower side of the layer arrangement shown.

Depending on the electrode materials used and the intended use of the optoelectronic component, for example in the form of a solar cell or a light-emitting diode, the strip electrodes within a pair of strip electrodes P have a mutual spacing b between 300 nm and 1.5 μm. The extension of the strip electrodes normal to the transition plane 7 typically measures at least 0.5 times, but preferably twice the length of the strip electrode spacing. In this way, especially when using the optoelectronic component as a solar cell, long absorption paths for that through the transition level 7 light entering the organic material can be realized. The strip electrode distances are preferably chosen to be largely constant, but deviations with distance fluctuations of 5% can occur due to process-related manufacturing tolerances.

As further below with reference to 9 in a preferred embodiment, the intermediate layers are also executed 6 according to 1a replaceable by providing organic material layers. In the case of in 1a Layer sequence shown are the layer thicknesses of the electrically and optically inactive intermediate layers 6 preferably chosen less than the organic material layer thicknesses 6 within the strip electrode pairs P, in order to realize an optoelectronic component which is as effective as possible, the energy efficiency of which is ultimately determined by the quality and extent of the energy conversion in the volume regions of the organic material layers.

With the multiple arrangement according to the invention of the stacked strip electrode pairs P, which are based on the respectively enclosed organic material layer 1 provide an aspect ratio of preferably 2, ie ratio between length 1 and width b of the material layer 1 , and the smallest possible duty cycle, ie the ratio between the overall structure width of a pair of strip electrodes P and the mutual distance between two adjacent pairs of strip electrodes, it is possible to create a large optically effective surface through which light can freely enter the material layer 1 can enter or leave this, at the same time for a large effective layer thickness 1 is taken care of, which ultimately ensures increased absorption in the case of a solar cell and effective light generation in the case of a light-emitting diode.

It is also with the in 1a layer structure shown possible to realize a partially transparent solar cell, since the highly reflective back contact typical for solar cells can be dispensed with. Rather, the partial transparency of the respective organic material layers allows 1 two or more such layer structures interconnect. So-called tandem solar cells can thus be implemented in a simple manner.

The inventive stacked multiple arrangement of individual pairs of strip electrodes also opens up completely new power ranges for the operation of solar cells and also for organic light-emitting diodes. If, for example, adjacent pairs of strip electrodes P in the in 2a electrically connected in series as shown, the operation of the optoelectronic components as organic solar cells results in much higher voltages than is possible with conventional solar cells constructed with conventional planar technology. Organic light-emitting diodes can also be operated with the stacked strip electrode structure according to the invention with much higher operating voltages than in the case of conventional organic light-emitting diodes.

Considerations as well as tests that have already been carried out show that multiple stacked series connection of strip electrode pairs connected in series achieves operating voltages which would destroy the optoelectronic component itself. In order to avoid such high operating voltages, individual or certain groups of strip electrode pairs connected in series can be connected in parallel with one another, as is shown schematically in FIG 2 B evident. The parallel connection according to 2 B leads to an interdigital arrangement of the individual strip electrodes, to which the same electrical voltage is applied. Both types of interconnection shown acc. 2a and b can thus be combined with one another in a suitable manner with regard to individual circuit requirements, but in particular to avoid excessive voltages.

In the case of the mode of operation of the optoelectronic component designed according to the invention as a solar cell, it is important in detail that the light-induced electron-hole pairs within the organic, photoactive material layer 1 to separate and dissipate via the respective strip electrodes in order to be able to tap the solar voltage applied to the strip electrodes. In order to improve the process of charge carrier separation and derivation within the photoactive organic material to the respective strip electrodes, it is important to optimize the charge carrier mobility of the electrons and also holes within the organic material layer. In this context, the structure of the strip electrode arrangement according to the invention, but in particular the manufacturing method according to the invention, helps to influence the charge carrier transport described above in an advantageous manner. As already briefly explained at the beginning, the individual strip electrodes are completely produced in a first method step, so that the gaps between the strip electrodes of a pair of strip electrodes only have to be filled in a subsequent method step. A first process variant provides that flowable, organic material - as a rule the flowable material is present as a mixture in combination with a solvent which solidifies after the solvent has evaporated - is introduced into the spaces between the strip electrode pairs, while between the strip electrodes of a strip electrode Pairs an electrical voltage to generate an electrical field. Even while the organic material is in the flowable state, the polymer chains contained within the organic material align themselves along the electrical field and remain with this orientation within the solidifying polymer matrix. Such a spatial alignment of the polymer chains between the strip electrodes within the organic material along the electrical field lines ultimately leads to an optimization of the charge carrier mobility with regard to electron and hole mobility within the organic material.

An alternative variant for introducing the organic material into the intermediate space of a pair of strip electrodes provides for the alternating introduction of p- and n-conducting organic material layers by means of a targeted vapor deposition process. It is thus possible, by alternately evaporating p- and n-conducting organic materials, which come from the group of oligomers, to fill in the interstices between two pairs of strip electrodes alternately in layers. The individual p- and n-type organic material layers are deposited perpendicular to the two opposite strip electrodes of a pair of strip electrodes. Such a layered organic material layer structure is shown in 3 shown. Here, the strip electrode pairs P are filled flush with n- and p-type organic layers. Strikes light across the transition plane 7 into the organic layer structure of the respective strip electrode pairs, electron-hole pairs generated within the organic material layer are separated by the potential gradient existing due to the different electrical work functions of the respective strip electrode materials. The holes are dissipated along the p-layer, the electrons along the n-layer to the respective strip electrodes. What is essential here is the improved mobility of the charge carriers in the respective material layers for both charge carrier types compared to conventional organic materials.

To produce the individual n- and p-conducting organic material layers, two evaporator sources are used, which have the corresponding layer materials, both of which are opposite to the one to be steaming strip electrode arrangement are positioned and alternately covered by a corresponding shutter device for selective vapor deposition.

In the same way as the above, advantageous Effects for improved carrier mobility can be used to implement solar cells also for the production and operation of organic light emitting diodes in use to be brought.

In the production of organic light-emitting diodes, for example, the targeted alignment of suitable asymmetrical molecules or particles, which are contained in the flowable organic material and whose orientation and alignment, which are determined by a given E field, are retained even in the solidified state of the organic material, leading to completely new properties such LEDs. In 4 is a schematic cross section through an organic light emitting diode structure, which provides an organic polymer matrix in the space between the pairs of strip electrodes, within the photoactive molecules or parts 8th are provided which emit highly polarized light with appropriate electrical excitation. As in the exemplary embodiment given, are the light-emitting particles 8th Aligned at a macroscopic level, the surface emits polarized light. Compared to polarization by filtering unpolarized light, this is a very efficient way of generating polarized light. Prerequisite for the polarizability of the particles 8th is a strong dipole moment, which is fulfilled by certain nanocrystals. Such nanocrystals are preferably CdSe or CdS nanocrystals which are contained in the CdSe / P3HT or CsS / P3HAT mixtures. Such photoactive particles are described, for example, in the article by C. Chen "Photoluminescence from single CdSequantum rods", Journal of Luminescence 97 (2002), p. 205-211.

Because the particles 8th Due to the manufacturing process, with their longitudinal axis parallel to the field lines of the electric field between two strip electrodes and thus oriented orthogonally to the strip electrode surfaces, the stacked or vertical arrangement of the strip electrodes ideally leads to a polarization direction orthogonal to the strip electrodes and thus orthogonal to the normal vector of the transition plane 7 (see arrow representations).

In addition, if the periodic recurrence of adjacent pairs of strip electrodes is in the order of the light wavelength emitted by the photoactive particles, the emission behavior of a light-emitting diode operated in this way can be influenced in a targeted manner by dimensioning the individual pairs of strip electrodes and their mutual spacing. Diffraction effects can occur at the transition level 7 due to the strip electrode spacing.

Furthermore, the manufacturing process according to the invention is described for the optoelectronic component described above in detail.

As already mentioned, it applies in a first process step manufacture the strip electrode assembly before layers of organic material in the corresponding spaces between two adjacent strip electrodes. One is required to produce the strip electrode arrangement targeted structuring of a flat substrate that serves as a basic structure preferably has parallel ribs. For generation of such a linear surface relief grating typically in the form of parallel ribs with structure sizes in the micrometer range, photolithographic processes are suitable, such as interference lithography. After corresponding Pattern formation takes place within an exposed photoresist mostly a galvanic impression in a nickel surface, the ultimately as an embossing tool serves to replicate the microstructure in plastics. For the production A number of such structured substrate surfaces are suitable Process techniques known from the prior art, to which this point is not dealt with in detail.

In the 5a and b is an example of a structured sheet substrate shown in cross section 6 shown, the rib-like elevations that extend above its substrate surface and run parallel to one another 61 having. The individual surveys 61 have side flanks which are oriented parallel to one another and which are successively acted upon by appropriate metal layers by means of metallic oblique vapor deposition. The oblique vapor deposition of the elevations 61 takes place in two steps, a first step in which according to 5a the respective left-hand side flanks are coated with a metal layer and a second vapor deposition process in which the right-hand side flanks are covered with a corresponding metal layer. The oblique vapor deposition takes place in such a way that only the side flanks of the elevations 61 are metallized, but not the surfaces of the structured substrate present between the elevations. Depending on the later use of the optoelectronic component to be obtained, identical or different electrode materials are formed on the surfaces of the elevations in both oblique vapor deposition steps 6 deposited.

Due to the successive oblique vapor deposition, both the left and the right side flanks of the elevations 61 according to the 5a and b , should no further measures have been taken, both metal deposits on the respective caps of the elevations short-circuited by mutual superposition.

In this way, a series connection of adjacent pairs of strip electrodes is automatically created, as shown in the schematic illustration 2a can be seen. In this circuit variant, the level of the electrical voltage in the case of an organic light-emitting diode which has to be applied for operation or which can be tapped at the organic solar cell is determined by the number of strip electrode pairs connected in series. In order to prevent the electrical voltage from rising too much, an electrical interruption in parallel with the electrodes ensures that the corresponding electrical voltage can be predetermined to a defined level.

In order to avoid the ohmic contact between the metal deposits on the side flanks of an elevation at the cap area, which occurs as a result of the oblique vapor deposition described above, two measures are basically available. So it is possible on the one hand, according to 6a the short-circuited caps of the surveys 61 by means of an anisotropic etching process, so that only the spatially separated strip electrodes on the side flanks of the elevations 61 according to the in 6a shown manner can be obtained.

Alternatively, an intermediate separation of electrically insulating material helps 9 for spatial spacing of both metallizations in the cap area of the elevations 61 , Here, after the first oblique steaming acc. 5a has been carried out, electrically insulating material 9 only on the cap area of the surveys 61 deposited. The second oblique vaporization then takes place as explained above. The result is a metallization on the individual surveys 61 received as in 6b shown to produce a in 2d parallel connection of individual pairs of strip electrodes or groups of strip electrode pairs connected in series should be shown in the 7a to d referenced process steps for the formation of interdigital electrodes.

In 7a suppose that the sheet substrate 6 a multiplicity of parallel ones lying across the plane of the flat substrate 6 raised single rib-like elevations 61 having. The next step is a partial masking 10 in the in 7b shown way on the flat substrate 6 as well as the upper areas of the surveys 61 applied. This is followed by oblique steaming from the left side as shown by the arrow in 7b , through which the side flanks of the elevations oriented to the left 61 as well as the lower area of the substrate 6 be metallized. After performing the metallization according to 7b are in detail through the lower electrode area 11 strip electrodes electrically contacted with each other, each of the left side flanks of the elevations 61 clothe.

In a further process step, the electrode area 11 covered with a slight oversize, so that even the lowest areas of the surveys 61 from partial masking 12 be covered. Now there is an oblique vapor deposition from the right side, through which the side flanks of the individual elevations oriented to the right 61 be metallized. In addition, the upper area of the flat substrate 6 metallized on which an electrode surface 13 arises, each the strip electrodes, located on the right side flanks of the bumps 61 train, electrically contacted with each other. A process is not shown with which the uppermost caps of the elevations are separated off, as a result of which short circuits on the upper caps of the individual elevations are avoided. As a result, an interdigital electrode arrangement as shown in FIG 7d receive.

The above process steps were used to produce the strip electrode structure with corresponding Interspaces with an electrically conductive photoactive organic material to fill.

In 8th is a schematic cross-sectional image through the metallized side flanks of a structured substrate 6 shown, which is filled by appropriate dipping or spin-coating with photoactive material, preferably photoactive polymer or oligomer. As already mentioned several times, the photoactive organic material is in a pourable form for filling, which solidifies and assumes a solid form after appropriate filling and volatilization of the solvent contained. In 9a is the photoactive polymer 1 solidified and leveled its surface.

At this point, two alternative additional process paths basically open up. On the one hand, it is possible to remove the organic material and the substrate appropriately flush 6 the layer structure according to the embodiment 1a to obtain. On the other hand, according to 9b the organic material including the strip electrode arrangement are separated from the substrate itself using a lift-off step. The remaining electrode gaps are then filled with organic material, so that a strip electrode arrangement according to the image in 9c is obtained. This embodiment does not see an inactive intermediate area 6 before, but consists entirely of the electrically conductive organic material 1 , in which only the strip electrodes 4 . 5 are included. This embodiment can be regarded as an optimized variant of an optoelectronic component with which particularly high energetic efficiencies can be achieved.
