Description

1. Anwendungsgebiet1. Application

Die Erfindung betrifft eine Fotozellenanordnung zur Erzeugung elektrischer Energie mit einem zugeordneten optischen Element mit Linsencharakteristik.The The invention relates to a photocell arrangement for generating electrical Energy with an associated optical element with lens characteristic.

Das optische Element ist eine Hologrammfolie, welches aus dem einfallenden Licht einen Teil dessen Spektrums auf die Fotozelle, mit kleinerer Fläche, fokussiert und der Sonne nicht nachgeführt werden muss. Diese Anordnung befindet sich zwischen einer hoch transparenten Scheibe und bildet damit das Modul. Mehr als 80% der Modulfläche können dadurch transparent bleiben, so dass es vorzugsweise in Gewächshäusern, anstelle eines einfach verglasten Daches, eingesetzt werden kann, ohne den Pflanzen zu viel Licht zu nehmen.The optical element is a hologram foil, which consists of the incident Light a part of its spectrum on the photocell, with smaller area, focused and the sun does not need tracking. This arrangement is located between a highly transparent Disc and thus forms the module. More than 80% of the module area This allows it to remain transparent, so it's preferable in greenhouses, instead of a simply glazed Roof, can be used without the plants too much light to take.

2. Stand der Technik2. State of the art

Solarzellenanordnungen dieser Art sind bekannt. Bekannt ist auch das eine teure Zellmaterialersparnis durch vergleichbar billige Optik erreicht wird.solar cell arrays of this kind are known. Also known is an expensive cell material savings is achieved by comparable cheap optics.

Ein realisiertes Projekt der noch jungen Technologie ist der FLATCON des Fraunhofer Instituts, nachzulesen in der wissentlichen Veröffentlichung 2007 (Forschungsgebiet: Solarzellen, Regenerative Stromerzeugung im Netzverbund). Aus dieser Veröffentlichung ist zu entnehmen, dass das optische Element eine Fresnel-Linse ist, die das Licht 500-fach punktuell auf die Fotozelle konzentriert. Nachtteilig ist, dass das System der Sonne nachgeführt werden muss. Dies macht das System durch eine zweiachsige Nachführung und einer Regelungstechnik aufwendig.One Realized project of the still young technology is the FLATCON of the Fraunhofer Institute, to be read in the scientific publication 2007 (research field: solar cells, regenerative power generation in the network). From this publication it can be seen that the optical element is a Fresnel lens, the light 500 times concentrated on the photocell. Night part is that the system of the sun must be tracked. This makes the system by a two-axis tracking and a Control technology consuming.

Aus einer weiteren Veröffentlichung US 4,204,881 ist das Prinzip der spektralen Zerlegung des Lichtes mit einem diffraktiven optischen Element bekannt, so dass auf diese Veröffentlichung verwiesen werden kann. Nachtteilig ist die schwer zu justierende Fotozellanordnung, sowie deren großen Raumbedarfs.From another publication US 4,204,881 For example, the principle of spectral decomposition of light with a diffractive optical element is known, so that reference can be made to this publication. Nachtteilig is difficult to adjust photocell arrangement, and their large space requirements.

Es gibt auch Versuche, mit Hologrammen Solarstrahlung zu bündeln, um Silizium einzusparen. Nachteilig ist die Erwärmung der Zellen und der dadurch notwendige Kühlungsbedarf.It there are also attempts to bundle solar radiation with holograms, to save silicon. The disadvantage is the warming of the Cells and the necessary cooling demand.

3. Ziel der Erfindung3. Object of the invention

Daher ist es Ziel der Erfindung, der eingangs genannten Art, eine Fotozellenanordnung zu schaffen, die sich wirtschaftlich und mit geringem Aufwand herstellen lässt. Wie eingangs erwähnt ist ein weiteres Ziel der Erfindung der Einsatz des Moduls in Gewächshäusern.Therefore It is the object of the invention of the type mentioned, a photocell arrangement to create, which produce economically and with little effort leaves. As mentioned above is another goal the invention of the use of the module in greenhouses.

Vorzugsweise hat das Modul ein annähernd gleiche bis doppelte Masse wie eine konventionelle Dachverglasung. Des weiteren wird trotz der Fotomaterialstreifen eine hohe Transparenz erreicht. Dies ist zurückzuführen auf die Funktionsweise der Hologrammfolie, welche nur ein Teil des Lichtspektrums, und zwar den, der nicht zur Photosynthese benötigt wird, fokussiert und den Rest durchlässt. Damit wird durch den Focus die Photozelle nur in geringem Maße erwärmt.Preferably the module has an approximately equal to double mass like a conventional roof glazing. Furthermore, despite the photo material strip reaches a high transparency. This is due to the functioning of the hologram foil, which only a part of the light spectrum, namely the one that does not needed for photosynthesis, focused and the rest pass through. Thus, the focus is the photocell only heated to a slight extent.

Ein weiteres Ziel der Erfindung ist, dass bei etwaigen Beschädigung des Moduls keine Gefahr für Mensch und Tier besteht, da es mit der auflaminierten Folie als Glasverbundscheibe wirkt.One Another object of the invention is that in case of damage the module is no danger to humans and animals, since it acts with the laminated film as a glass composite pane.

4. Darlegen des Wesens4. expounding the essence

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur spektralen Fokussierung der Lichteinstrahlung gemäß dem Ziel der Erfindung zu schaffen. Erfindungsgemäß besteht das optische Element aus einer holographischen Folie. Das auf die Hologrammfolie auftreffende Licht von der Sonne wird spektral aufgeteilt und lediglich der Wellenlängenbereich zwischen 450 nm–650 nm in einer Variante auch der Wellenbereich zwischen 750 nm und 1.100 nm konzentriert sich auf der Fotozelle.Of the Invention is based on the object, a device for spectral Focusing the light irradiation according to the target to provide the invention. According to the invention the optical element of a holographic film. That on the hologram foil incident light from the sun is spectrally split and only the wavelength range between 450 nm and 650 nm in a variant also the wave range between 750 nm and 1,100 nm focuses on the photocell.

Vorzugsweise besteht das Fotozellenmaterial aus monochristallinem Silizium, auch andere Halbleitermaterialien sind möglich.Preferably For example, the photocell material is monocrystalline silicon, too other semiconductor materials are possible.

In 1 ist schematisch ein Schnittbild der erwähnten Anordnung dargestellt. Auf der hochtransparenten Glasscheibe 1 ist ein Hologramm H laminiert. Dahinterliegend befindet sich die Fotozelle 2. Vorzugsweise wird ein Größenverhältnis 10:1 gewählt um die Zelle nicht zu stark zu erwärmen. Um die Nachführung zur Sonne zu vermeiden wird eine Focusierung programmiert die breiter als die Fotozelle ist.In 1 is shown schematically a sectional view of the mentioned arrangement. On the highly transparent glass pane 1 is a hologram H laminated. In the background is the photocell 2 , Preferably, a 10: 1 aspect ratio is chosen so as not to overheat the cell. In order to avoid tracking to the sun, a focusing is programmed which is wider than the photocell.

Der Lichtstrahl S wird am Hologramm spektral aufgeteilt, dabei wird das kurzwellige, blaue Licht S3 stärker als das langwellige, rote Licht S1 gebrochen. Der mittlere Spektralbereich S2, grünes Licht, wird auf die Fotozelle fokussiert.Of the Light beam S is spectrally split at the hologram, thereby the short-wave, blue light S3 stronger than the long-wave, broken red light S1. The mean spectral range S2, green Light, is focused on the photocell.

In 2 wird schematisch der Einsatz eines solchen Moduls 2 in einem Gewächshaus 1 dargestellt. Um ein optimales Lichttransparenz zu ermöglichen und die Pflanzen im Gewächshaus ausreichend mit Licht zu versorgen, wird jede 2. Dachverglasung 3 konventionell mit einer Glasscheibe bestückt. Die Hologramme sind derart optimiert, dass bei flacher Sonneneinstrahlung, also im Winter, sowie am Morgen und Abend das Licht nicht auf die Fotozelle fokussiert wird, sondern nur durch die Beschattung der Fotozelle der Lichteinfall ins Gewächshaus vermindert wird. Damit wird der Lichtmangel im lichtarmen Winter vermieden.In 2 will schematically illustrate the use of such a module 2 in a greenhouse 1 shown. Every second roof glazing becomes possible in order to provide optimum transparency and to supply the plants with sufficient light in the greenhouse 3 conventionally equipped with a glass pane. The holograms are optimized in such a way that in shallow sunlight, ie in winter, as well as in the morning and evening, the light does not affect the photocell fo is kissed, but only by the shading of the photocell, the light is reduced to the greenhouse. This avoids the lack of light in the light winter.
