Abstract

Solar-energy installation with photo-electric cells which can be directly exposed to the rays of the sun, in which installation either the photo-electric cells directly form a parabolic effective surface, or a parabolically curved, selective filter covering the photo-electric cells is provided. The surface is curved in such a way that the rays of the sun impinging thereon and reflected thereby are concentrated into a focal point or a focal line. There is provided, in the focal point or the focal line, a secondary energy converter in the form of a thermal absorber or secondary solar cells for absorbing the reflected rays. The selected solar radiation impinging on the photo-electric cells is optimally utilised in this arrangement by virtue of the photo-electric cells in conjunction with the secondary energy converter.

Description

Solarenergieanlage mit Photozellen Solar energy system with photocells

Die Erfindung bezieht sich auf eine Solarenergieanlage mit Photozellen, die den Sonnenstrahlen direkt aussetzbar sind.The invention relates to a solar energy system with photocells, which can be exposed directly to the sun's rays.

Photozellen werden zunehmend zur Nutzung der Strahlenenergie für die Stromerzeugung eingesetzt, wobei insbesondere flache, direkt von Sonnenlicht beschienene Zellen benutzt werden, die auch diffuses Licht nutzen.Photocells are increasingly used to use the radiation energy for the Electricity generation used, in particular flat, directly lit by sunlight Cells are used that also use diffuse light.

Unter direkter Einstrahlung wird eine Anordnung verstanden bei der die Photozellen ohne Zwischenschaltung von Konzentratoren, so wie Reflektoren oder Linsen den Sonnenstrahlen ausgesetzt sind.Direct irradiation is understood to mean an arrangement in the photocells without the interposition of concentrators, such as reflectors or Lenses are exposed to the sun's rays.

Selbst bei direkter Sonnenbestrahlung können die Photozellen bis ca. 80°C aufgeheizt werden. Derartig hohe Betriebstemperaturen führen jedoch zu einem entsprechend geringen Wirkungsgrad, der einen elektrischen Leistungsverlust bis zu 20% mit sich führt.Even in direct sunlight, the photocells can reach up to approx. 80 ° C. However, such high operating temperatures lead to a correspondingly low efficiency, which results in an electrical power loss up to carries 20% with it.

Es ist eine Solarenergieanlage der oben genannten Art bekannt (DE-OS 28 47 433), bei der die Zellen den Grund eines warmeisolierenden Kastens niit klartransparenter Stirnfläche bilden. Innerhalb dieses Kastens fließt ein Wärmeträger, der gleichzeitig die Solarzellen kühlt.A solar energy system of the type mentioned above is known (DE-OS 28 47 433), in which the cells form the bottom of a warm-insulating box with less clear transparency Form face. Inside this box, a heat transfer medium flows at the same time cools the solar cells.

Hierbei falls eine Kühiwärme mit einem relativ niedrigen Temperaturniveau von 50 bis 60 C an. An einer Nutzung dieser Abwärme ist daher kaum zu denken.In this case, a cooling heat with a relatively low temperature level from 50 to 60 C. It is therefore hard to think of using this waste heat.

Der Erfindung liegt die Aufgabe zugrunde, eine Anlage der eingangs genannten Art zu schaffen, mit dem ein optimaler Wirkungsgrad erreicht werden kann.The invention is based on the object of providing a system of the initially mentioned to create the type mentioned, with which an optimal degree of efficiency can be achieved.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Photozellen nebeneinander eine parabolförmige Oberfläche bildend angeordnet sind derart, daß die von den Zellen reflektierten Sonnenstrahlen sich auf einen Brennpunkt oder eine Brennlinie konzentrieren, und daß in dem Brennpunkt bzw. der Brennlinie ein sekundärer Energiewandler vorgesehen ist.The object is achieved according to the invention in that the photocells are arranged side by side forming a parabolic surface such that the rays of the sun reflected by the cells focus on a focal point or a Concentrate focal line, and that in the focal point or the focal line a secondary Energy converter is provided.

Hiermit bildet die Anlage gleichzeitig einen strahlenkonzentrierenden Reflektor, der einerseits die vor den Photozellen absorbierten Sonnenstrahlen in elektrische Energie umwandelt und andererseits die übrigen Strahlen auf einen sekundaren Energiewandler reflektiert. Hierdurch kann die auf die aktive Photozell-enflache auftreffende Sonnenstrahlung nahezu voll genutzt und damit der Wirkungsgrad gegenüber den bisher bekannten Anlagen wesentlich verbessert werden.In this way, the system also forms a beam-concentrating Reflector, which on the one hand converts the sun's rays absorbed in front of the photocells converts electrical energy and on the other hand the remaining rays to a secondary Energy converter reflected. This can affect the active photocell surface incident solar radiation is almost fully used and thus the efficiency compared the previously known systems are significantly improved.

Die Tagesleistung der Anlage kann gemaß einer Weiterbildung der Erfindung dadurch erhöht werden, daß die Solaranlage der Sonnenbahn nachgeführt wird.The daily output of the system can according to a further development of the invention can be increased by the fact that the solar system tracks the path of the sun.

Gemaß einer weiteren Ausgestaltung der Erfindung sind die Photozellen mit selektiven Filtern beschichtet, die die von der Zelle nicht nutzbaren Wellenlängen (UV + IR) reflektiert und die übrigen Wellenlängen durchlaßt.According to a further embodiment of the invention, the photocells are coated with selective filters, which are the wavelengths that cannot be used by the cell (UV + IR) reflects and transmits the other wavelengths.

Hiermit wird die Wärmebelastung und damit die Leistungsminderung der Solarzellen reduziert. Außerdem kann der selektive Filter gleichzeitig die Deck- bzw. Schutzschicht für die Zellen bilden und damit etwaige Schutzgläser ersetzen.This reduces the heat load and thus the reduction in performance of the Solar cells reduced. In addition, the selective filter can simultaneously control the deck or form a protective layer for the cells and thus replace any protective glasses.

In diesem Fall ist es ferner vorteilhaft, wenn der sekundare Energiewandler ein thermischer Absorber ist.In this case it is also advantageous if the secondary energy converter is a thermal absorber.

Mit der erhöhten UV- und IR-Refl ektionsstrahl ung kann somit ein hohes nutzbares Temperaturniveau im Absorber erzeugt werden.With the increased UV and IR reflective radiation, a high usable temperature level can be generated in the absorber.

Gemäß eine weiteren Ausgestaltung der Erfindung kann mit dem sekundären Energiewandler zusätzlich elektrische Energie erzeugt werden, indem beispielsweise im Brennpunkt bzw. in der Brennlinie weitere Solarzellen angebracht werden.According to a further embodiment of the invention, the secondary Energy converter also generates electrical energy by, for example further solar cells are attached in the focal point or in the focal line.

Die oben genannte Aufgabe ist gemäß einer anderen Ausführungsform der Erfindung auch dadurch gelöst, daß die Photozellen mit einem parabolisch gewölbten, selektiven Filter abgedeckt sind derart, daß die von dem Filter reflektierten Sonnenstrahlen sich auf einen Brennpunkt oder eine Brennlinie konzentrieren, und daß in dem Brennpunkt bzw. der Brennlinie ein sekundarer Energiewandler vorgesehen ist.The above object is according to another embodiment the invention also achieved in that the photocells with a parabolically curved, selective filters are covered in such a way that the sun rays reflected by the filter concentrate on a focal point or a focal line, and that in the focal point or a secondary energy converter is provided for the focal line.

In dieser Ausführung können die Solarzellen auf einer Ebene angeordnet werden, während der Filter die Funktion eines Reflektors einnimmt. In diesem fertigungstechnisch einfacheren Fall wird ebenfalls die Kapazität der Solarzellen durch die Abschirmung der die Zellen wärmenden Strahlung optimal genutzt, wobei die vom Filter reflektierte Strahlung ebenfalls nur Erzeugung von Wärme höheren Temperaturniveaus bzw. zusätzlicher Elektrizität genutzt wird.In this embodiment, the solar cells can be arranged on one level while the filter takes on the function of a reflector. In this manufacturing technology A simpler case is also the capacity of the solar cells due to the shielding the radiation that warms the cells is optimally used, with the radiation being reflected by the filter Radiation likewise only produces higher heat Temperature levels or additional electricity is used.

In the focal point 26 there are further solar cells or a thermal absorber 27 is arranged. The entire system 20 is on one supporting structure 30 rotatable about a vertical axis 28 and a horizontal axis 29, 31 arranged.

Hiermit kann die Anlage 20 schrittweise oder kontinuierlich bewegt werden derart, daß die einfallenden Strahlen 24 stets den optimalen Einfallswinkel beibehalten können.In this way, the system 20 can be moved gradually or continuously are such that the incident rays 24 always have the optimal angle of incidence can maintain.

Die Anlagen können auch mit ebenen Photozellenträgern 21, wie in Fig. 2 gestrichelt dargestellt, und lediglich mit gekrümmten Filtern ausgestattet sein.
