Definitions
- Organic photoactive component in particular organic solar cell or organic photodetector
- the invention relates to an organic photoactive component, in particular an organic solar cell or an organic photodetector, with a layer arrangement comprising an electrode and a counter electrode and a sequence of organic layers, which is arranged between the electrode and the counter electrode, and which additionally comprises at least one organic and / or inorganic layer which serves as a cover layer for improving the light coupling in a broad spectral range.
- an organic photoactive component in particular an organic solar cell or an organic photodetector
- a layer arrangement comprising an electrode and a counter electrode and a sequence of organic layers, which is arranged between the electrode and the counter electrode, and which additionally comprises at least one organic and / or inorganic layer which serves as a cover layer for improving the light coupling in a broad spectral range.
- Organic solar cells consist of a series of thin layers, which typically have a thickness of between 1 nm and 1 ⁇ m, of organic materials which are vapor-deposited in vacuum or applied from a solution.
- the electrical contacting is generally carried out by transparent, semitransparent or non-transparent metal layers and / or transparent conductive oxides (TCOs) and / or conductive polymers.
- a solar cell converts light energy into electrical energy.
- solar cells do not directly generate free charge carriers due to the light, but excitons are first formed, ie electrically neutral excitation states, namely bound electron-hole pairs. These excitons can only be separated by very high electric fields or at suitable interfaces.
- organic solar cells sufficiently high fields are not available, so that all promising concepts for organic solar cells are based on excision separation at photoactive interfaces (organic donor-acceptor interface - CW Tang, Appl. Phys. Lett., 48 (2), 183-185 (1986)) or interface to one inorganic semiconductors (see B. O'Regan et al., Nature 353, 737 (1991)). This requires that excitons generated in the bulk of the organic material can diffuse to this photoactive interface.
- a layer contains a colloidally dissolved substance which is distributed so as to form a network through which charge carriers can flow (percolation mechanism).
- the task of light absorption takes over in such a network either only one of the components or both.
- the advantage of such a mixed layer is that the generated excitons only have to travel a very short distance until they reach a domain boundary where they are separated. The removal of the electrons and the holes takes place separately in the dissolved substance or in the remaining layer.
- the active layer consists of an organic semiconductor in a gel or binder (US 3,844,843, US 3,900,945, US 4,175,981 and US 4,175,982).
- a layer contains two or more types of organic pigments which have different spectral characteristics (JP 04024970).
- One layer contains a pigment that generates the charge carriers, and in addition a material that carries away the charge carriers (JP 07142751).
- Inverted solar cells have the great advantage that one no longer necessarily relies on glass substrates and expensive transparent conductive oxides as electrodes, but has the choice of a wide variety of substrates and applications.
- tandem, triple or generally multiple cells consisting of a stack of several solar cells, so that the multiple cell can absorb in a broad spectral range by different absorber materials, each of which absorbs only a certain part of the spectrum , As a result, significantly higher efficiencies can be achieved than with single cells;
- the tandem / multiple cell technology also shows once again that a broad spectral range is necessary for efficient solar cells; the problem of multiple cells has been described in the publications by Agrawal / Peumans and O'Connor et al. not treated
- the object of the present invention is the optimization of the light coupling and reduction of the reflection of a broad spectral range of the visible light in an organic photoactive component, in particular an organic solar cell or an organic photodetector. According to the invention the object is achieved by an organic photoactive component having the features mentioned in claim 1.
- Advantageous embodiments are the subject of dependent subclaims. Advantageous uses arise from the claims 30 to 32.
- the organic photoactive component contains at least one further layer, which consists of at least one organic or inorganic material or a combination of organic or inorganic materials, which improves the efficiency of the photoactive component by improved light coupling and / or reduced reflection and / or optimization of the optical field increased inside the solar cell by forming a microcavity.
- This layer is referred to below as a transparent cover layer or cover layer, wherein the layer thickness of the transparent cover layer or cover layer, denoted as D, of the relationship

- An advantageous embodiment of the invention contains in the HTL materials serving as dopants (acceptors) for the materials which preferentially conduct positive charges (holes).
- HTL materials serving as dopants (acceptors) for the materials which preferentially conduct positive charges (holes).

- the present invention has succeeded in reducing inverted organic solar cells by the application of cover layers not only the reflection of the upper electrode, but in particular to control the distribution of the optical field in the interior of the solar cell. It is exploited that between a reflective electrode (eg, a thick aluminum layer) and a semi-transparent electrode (eg, but not limited to a very thin metal layer), which acts as a dielectric mirror, a microcavity is formed, and the microcavity within the solar cell specifically exploited and adapted.
- a reflective electrode eg, a thick aluminum layer
- a semi-transparent electrode eg, but not limited to a very thin metal layer
- An advantage of the inventive solution is that in particular the spectrum of the absorber is fully utilized (not only monochromatic light) the light coupling over a wide angle range works (not only directly perpendicular to the solar cell ein fallendes, but also important for solar cells diffused light) ideal way not only the optical field is optimally distributed in the cell, but an anti-reflection effect can be used as a side effect with
- the structure of the solar cell can be varied if necessary

- Fig. 2 shows another archetypal organic solar cell
- Fig. 3 shows another archetypal organic solar cell

- the organic layers between the two metal contacts referred to in the figures as "organics,” form a microcavity together with the aluminum transparent cover contact.
- This part of the solar cell which may include layers acting as landing transporters, absorbers, exciton blockers, etc. in the following the term "cavity”.
- the "cavity length" is determined by the sum of the organic layer thickness and the layer thickness of the transparent cover contact, which simultaneously acts as part of the cavity and as the second partial mirror.
- the figures show the amplitude of the optical field inside the solar cell depending on the position at which you are in the solar cell. It is essential here that the distribution of the optical field is independent of the exact structure of the solar cell or the materials used in the individual case, but the cavity length is the deciding factor.
- FIG. 4 shows as Examples of different single cells of different cavity lengths (112nm, 127nm, 132nm) and different tandem cells of different cavity lengths (193nm, 333nm).
- these 5 possible solar cells were calculated by means of optical simulations, at which layer thickness of a cover layer, the optimal solar cell efficiency is achieved, wherein also any cover layers with arbitrary optical refractive index n were taken into account in the simulations.
- Decisive and surprising here is that for any solar cell with any cavity length and any cover layer with any optical properties optimal improvement of the solar cell performance can be achieved when the cover layer is applied with a layer thickness D in nanometers, the formula
- d (n) 201.9 -121, In + 20, ln 2 and n is the optical refractive index of the cover layer.

- the efficiency can be increased by more than 50% (from 0.69% to 1.06%) if the solar cell uses a 50 nm thick Alq3 transparent cover layer.
- the major part of the increase in efficiency is based on an increased photocurrent, which could be increased from 3.37 mA / cm 2 to 4.92 mA / cm 2 .
- the experimentally measured external quantum efficiency indicates the ratio between the power radiated from the outside into the solar cell and the power recovered from the solar cell
- EQE indicates the ratio between the power radiated from the outside into the solar cell and the power recovered from the solar cell
