Description

Die Erfindung betrifft eine Vorrichtung zur Umwandlung von Lichtenergie in elektrische Energie gemäß dem Oberbegriff des Anspruchs 1, wie sie aus Research Disclosure, Nr. 29, 1975, S. 20/21, bekannt ist. Diese bekannte Vorrichtung wird zur Anschaulichkeit in F i g. 1 dargestellt.The invention relates to a device for converting light energy into electrical energy according to the preamble of claim 1 as known from Research Disclosure, No. 29, 1975, pp. 20/21. These known device is shown for clarity in FIG. 1 shown.

Sonnenlicht (2) wird in einer transparenten Schicht, deren Brechungsindex größer als der des umgebenden Mediums ist und die Fluoreszenzzentren enthält (nachfolgend Konzentrator genannt) absorbiert und in Fluoreszenzlicht (3) umgesetzt. An den Stirnflächen sind Solarzellen vorgesehen, damit aber nicht alle Kanten mit den teuren Solarzellen versehen werden müssen, wird ein Teil der Stirnflächen (4) verspiegelt. Eine andere Möglichkeit, das Fluoreszenzlicht aus dem Kollektor auszukoppeln, besteht darin, verspiegelte Kerben (5) auf der dem Licht zugewandten Fläche vorzusehen und an der gegenüberliegenden Fläche die Solarzelle (7).Sunlight (2) is in a transparent layer whose refractive index is greater than that of the surrounding Medium is and contains the fluorescence centers (hereinafter referred to as concentrator) absorbed and in Fluorescent light (3) implemented. Solar cells are provided on the end faces, but not all of the edges must be provided with the expensive solar cells, a part of the end faces (4) is mirrored. One Another way of decoupling the fluorescent light from the collector is to use a mirrored Provide notches (5) on the surface facing the light and on the opposite surface Solar cell (7).

In der o.g. Literaturstelle ist weiterhin eine Anordnung mit mehreren Einzelschichten vorgesehen. Hierbei handelt es sich jedoch nur um einen einzigen Konzentrator, da diese Einzelschichten ausdrücklich optisch miteinander verbunden sine1. Die schichtweise Anordnung mit der die kurzwelligen Anteile absorbierenden Schicht auf der Oberseite bietet den Vorteil, daß die aus den unteren Schichten :m Verlustkegel (nicht im Winkelbereich der Totalreflexion) emittierten Lichtquanten in den darüberliegenden Schichten absorbiert werden und somit nicht verloren gehen.In the above-mentioned reference, an arrangement with several individual layers is also provided. However, this is only a single concentrator, since these individual layers are expressly connected to one another optically 1 . The layer-by-layer arrangement with the layer absorbing the short-wave components on the upper side offers the advantage that the light quanta emitted from the lower layers: m loss cone (not in the angular range of total reflection) are absorbed in the layers above and are therefore not lost.

Die optische Kopplung der Schichten führt aber andererseits dazu, daß nach kurzer Laufstrecke alle Quanten in die langwelligste Form umgevandelt werden. Das hat den Vorteil, daß sie dann ideal an einen Typ Solarzelle angepaßt werden können, aber den gravierenden Nachteil, daß ein Großteil der ursprünglichen Energie durch Stokesverluste im Kollektor zurückbleibtOn the other hand, the optical coupling of the layers leads to the fact that after a short walking distance all Quanta are converted into the longest wave form. This has the advantage that it is ideal for you Type solar cell can be customized, but the serious disadvantage that much of the original Energy remains in the collector due to Stokes losses

Aus der US-PS 34 26 212 ist weiterhin eine Vorrichtung mit Fluoreszenzzentren enthaltenden Schichten bekannt, wobei die eigentliche Solarzelle unter der untersten Schicht angeordnet ist Diese Vorrichtung arbeitet ebenfalls mit dem Prinzip der Degradation der Quanten, um sie an eine Solarzelle besser anzupassen. Sie hat jedoch gemäß Definition im Oberbegriff keinen Konzentrator zum Gegenstand.From US-PS 34 26 212 a device with fluorescent centers containing layers is also known, wherein the actual solar cell is arranged under the lowermost layer This device also works with the principle of quantum degradation in order to better adapt them to a solar cell. However, as defined in the generic term, it does not have a concentrator as its subject.

Aufgabe der Erfindung ist es, den Wirkungsgrad einer Vorrichtung der eingangs genannten Art wesentlich zu erhöhen. Dies wird erfindungsgemäß durch eine Vorrichtung nach Anspruch 1 erreicht Vorteilhafte Ausgestaltungen des Mehrfachkonzennators sind in den Unteransprüchen angegeben.The object of the invention is to substantially increase the efficiency of a device of the type mentioned at the beginning raise. This is achieved according to the invention by a device according to claim 1 Refinements of the multiple concenator are given in the subclaims.

Es ist der Grundgedanke der Erfindung, die verschiedenen Wellenlängenanteile des Sonnenlichts in optisch getrennten, -übereinanderliegenden Konzentratoren zu sammeln und angepaßten Solarzellen zuzuführen. Die Trennung der Konzentratoren durch ein Medium von geringerem Brechungsindex ist dabei absolut erforderlich, da sonst das in den einzelnen Konzentratoren geführte Licht nicht nach Wellenlängen getrennt an die Solarzellen gelangen könnte.It is the basic idea of the invention, the different wavelength components of the sunlight in To collect optically separated, superimposed concentrators and to supply adapted solar cells. The separation of the concentrators by a medium with a lower refractive index is included absolutely necessary, otherwise the light guided in the individual concentrators will not be based on wavelengths could reach the solar cells separately.

Nur durch diese Anordnung können die Stokesverluste in nennenswertem Umfang vermieden werden. Auch der Vorteil der Vorrichtung nach Research Disclosure, daß die aus den unteren Schichten im Verlustkegel (nicht im Winkelbereich der Totalreflexion) emittierten Lichtquanten in den darüberliegenden Schichten absorbiert werden und somit nicht verloren gehen, bleibt in der erfindungsgemäßen Vorrichtung erhalten.Only with this arrangement can the Stokes losses be avoided to a significant extent. Even the advantage of the device according to Research Disclosure that that from the lower layers in the loss cone (not in the angular range of total reflection) emitted light quanta are absorbed in the overlying layers and are therefore not lost, is retained in the device according to the invention.

F i g. 2 zeigt den Mehrfachkonzentrator mit hintereinander geschalteten Konzentratoren und Solarzellen. Konzentrator (IaJ ist se ausgelegt, daß die höheren Energieanteile des Sonnenlichts (2) einschließlich des UV, also die kürzeren Wellenlängen in Fluoreszenzlicht eines Bereiches ebenfalls kurzer Wellenlängen umgewandelt werden. Solarzelle (7a)\sl auf diesen Wellenlängenbereich angepaßt, d. h. besteht aus einem Halbleitermaterial von hohem Bandabstand. Da die in Konzentrator (Xa) eingelagerten Fluoreszenzzentren nur imF i g. 2 shows the multiple concentrator with concentrators and solar cells connected in series. Concentrator (IaJ is designed so that the higher energy components of sunlight (2) including UV, i.e. the shorter wavelengths, are converted into fluorescent light in a range of also short wavelengths. Solar cell (7a) \ sl adapted to this wavelength range, i.e. consists of a semiconductor material because the fluorescence centers embedded in the concentrator (Xa) are only present in the

Bereich kurzer Wellenlängen absorbieren, geht das Licht im darüberliegenden Wellenlängenbereich ungehindert hindurch und trifft auf den Konzentrator (16Jl der einen weiteren Wellenlängenbereich umwandelt und der Solarzelle (Jb) zuführt. (Jb) ist entsprechend ausgelegt, d. h. es besteht aus Halbleitermaterial von geringerem Bandabstand als (7ajl (Ic) und (Jc) sind dementsprechend an den !angwelligen Anteil angepaßt. F i g. 2 stellt nur eine beispielhafte Ausführungsform dar. Man kann mehr als 3 Schichten, aber auch nur 2 Schichten verwenden.If you absorb the range of short wavelengths, the light passes through unhindered in the wavelength range above and hits the concentrator (16Jl which converts another wavelength range and feeds it to the solar cell (Jb) . (Jb) is designed accordingly, i.e. it consists of semiconductor material with a band gap smaller than ( 7ajl (Ic) and (Jc) are adapted accordingly to the angular wave portion. Fig. 2 shows only an exemplary embodiment. You can use more than 3 layers, but also only 2 layers.

F i g. 3a zeigt Zweifachkonzentratoren von oben und Fig.3b dieselben im Querschnitt (la) sind die oberen Konzentratoren mit zugehörigen Solarzellen (7a), (Ib) sind die unteren Konzentratoren mit zugehörigen π Solarzellen (76JLF i g. 3a shows double concentrators from above and FIG. 3b shows the same in cross section (la) are the upper concentrators with associated solar cells (7a), (Ib) are the lower concentrators with associated π solar cells (76JL

In dieser Modifikation, siehe auch F i g. 4, besitzen die Konzentratoren (1) an gegenüberliegenden Rändern Krümmeransätze (11) zur 90°-Umlenkung des Lichts. Die Oberflächen der Krümmeransätze (11) sind zur Vermeidung von Lichtverlusten mit einem spiegelnden Belag (12) versehen.In this modification, see also FIG. 4, own the Concentrators (1) on opposite edges elbow extensions (11) for 90 ° deflection of the light. The surfaces of the elbow extensions (11) have a reflective finish to avoid light loss Cover (12) provided.

Nach Fig.4 können die Leiterbahnen von der Bestrahlung ausgespart werden und daher optimal dimensioniert werden. Dazu wird auf die Fluoreszenz- η licht-Austrittsfläche des Konzentrator eine Spiegelstruktur (9) aufgebracht, die genau der Leiterbahnstruktur (8) auf der Solarzelle (7) entspricht. Die Fluoreszenzlicht-Austrittsfläche und die Solarzelle werden dann über einen geeigneten Film (10) so miteinander in optischen Kontakt gebracht, daß sich die Strukturen (8) und (9) überdecken.According to FIG. 4, the conductor tracks can be left out of the irradiation and can therefore be optimally dimensioned. For this is applied to the fluorescent light-η-exit surface of the concentrator, a mirror structure (9), which corresponds to the solar cell (7) is exactly the conductor track structure (8). The fluorescent light exit surface and the solar cell are then brought into optical contact with one another via a suitable film (10) in such a way that the structures (8) and (9) overlap.

Die gute Transparenz der Konzentratoren macht auch die Ausnutzung der nicht durch Solarzellen umsetzbaren Wärmestrahlung möglich. Fig.5 zeigt, wie die IR-Strahlung (14) die Konzentratoren (la, Xb) durchsetzt und einen Strahlungsabsorber (13) für IR-Strahlung trifft, der diese restliche Strahlung in Wärme umwandelt.The good transparency of the concentrators also makes it possible to use the thermal radiation that cannot be converted by solar cells. 5 shows how the IR radiation (14) penetrates the concentrators (la, Xb) and hits a radiation absorber (13) for IR radiation, which converts this remaining radiation into heat.

Die Solarzellen mit selektiver Empfindlichkeit für Bereiche kurzer Wellenlängen haben einen erhöhten Wirkungsgrad bei höherer Lichtkonzentrierung und sind unempfindlich gegen höhere Temperaturen. Daher kann der Konzentrierungsfaktor für die verschiedenen Wellenlängenbereiche verschieden gewählt werden. Dieses ist dargestellt in F i g. 6 für Zweifachkonzentratoren. Für die oberen Konzentratoren (ta) mit zugehörigen Solarzellen (7a), die den Bereich kürzerer Wellenlängen aufnehmen, ist die Lichtkonzentrierung höher als für die unteren Konr*.iitratoren (\b) mit zugehörigen Solarzellen (7b), die rier: iängerweiiigen Bereich umsetzen.The solar cells with selective sensitivity for ranges of short wavelengths have an increased efficiency with a higher light concentration and are insensitive to higher temperatures. Therefore, the concentration factor can be chosen differently for the different wavelength ranges. This is shown in FIG. 6 for dual concentrators. For the upper concentrators (ta) with associated solar cell (7a) which accommodate the shorter wavelength region, the light concentration is higher than for the lower Konr * .iitratoren (\ b) with associated solar cell (7b), which rie r: iängerweiiigen area realize.

In den Solarzellen wird ein beträchtlicher Teil der Lichtenergie in Wärme umgesetzt. Um diese Wärme zu nutzer» und um die Solarzellen auf einer günstigen Temperatur zu halten, empfiehlt es sich, die Solarzellen zur Wärmeabfuhr auf einer Kühlvorrichtung zu montieren.A considerable part of the light energy is converted into heat in the solar cells. To this warmth too user »and to keep the solar cells at a favorable temperature, it is advisable to use the solar cells to be mounted on a cooling device for heat dissipation.
