Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur optimierten Fokussierung einfallenden Lichts auf photoaktive Polymere zur Erzeugung elektrischer Energie. Die Herstellung einer Photovoltaikanlagen bestehend aus einer Extruderfaser, deren Kern aus photoaktiven Polymeren besteht, stellt die Basis der vorliegenden Erfindung dar. Die Faser besteht aus einem transparenten, wahlweise beliebig eingefärbten, Mantel und einem photoaktiven Kern. Der Durchmesser der Faser und des Mantels ist dabei frei wählbar. Die Form des transparenten Mantels bestimmt die Fokussierung des Lichts im Inneren der Faser und ermöglicht damit eine optimale Auslastung des photoaktiven Materials im Kern. Dabei lassen sich durch die Einfärbung des Mantels gezielt bestimmte Wellenlänge des Lichts blockieren, so dass sie zudem photoaktiven Kern vordringen können. Die Fokussierung ermöglicht über einen oder mehrerer Schichten die Lichtbrechung dem jeweiligen Anwendungsfall anzupassen. Zudem kann ein Teilbereich des Mantels aus nicht-lichtdurchlässigen Werkstoffen, wie z. B. Karbon, gefertigt werden, um das Verhalten der Photovoltaikfaser dem jeweiligen Einsatz anzupassen.The The invention relates to a method for optimized focusing incident light on photoactive polymers to generate electrical energy. The production of a photovoltaic system consisting of an extruder fiber, whose core consists of photoactive polymers, provides the basis The fiber consists of a transparent, optional arbitrarily colored coat and a photoactive Core. The diameter of the fiber and the jacket is freely selectable. The Shape of the transparent shell determines the focus of the light inside the fiber, allowing for optimal Utilization of the photoactive material in the core. You can do that by the coloring of the coat purposefully certain wavelength Block the light so that they also penetrate the photoactive core can. The focus allows over one or more layers to adjust the refraction of light to the particular application. In addition, a portion of the shell of non-translucent Materials such. As carbon, are made to the behavior to adapt the photovoltaic fiber to the particular application.

Das Erhitzte und unter Druck stehende Polymer wird anschließend durch eine schmale Öffnung gepresst. Der benötigte Abguss, meist aus Eisen, ist dabei nicht einfach ein rundes Loch, sondern es muss sich um eine konische Öffnung handeln. Durch den Überdruck wird das Polymer durch den Abguss gepresst und wird dadurch zu einer Faser, die im Normalfall mehrere Meter nach dem Abguss aufgewickelt wird. Form und Durchmesser der Faser sind dabei von der Form des Abgusses abhängig. Dabei bestimmen die Gravitation, die Wickelgeschwindigkeit, die Temperatur und der Durchmesser des Abgusses den endgültigen Durchmesser der Faser und einige der Materialeigenschaften.

The required casting, usually made of iron, is included Not just a round hole, but it has to be a conical opening act. Due to the overpressure, the polymer is through the Casting pressed and thereby becomes a fiber, which normally several meters after the casting is wound up.

Aufgabenstellungtask
Verglichen mit Dünnschicht-Solarzellen oder konventionellen polykristalinen Solarzellen soll ein Verfahren vorgestellt werden, dass die vorgestellte Photovoltaik durch die Verwendung photoaktiver Polymere als Basis mit anderen Werkstoffen leichter verwendet oder kombiniert werden kann. Zudem ist diese Solarzelle flexibler und kann damit leichter in komplexen Formen verwendet werden oder beispielsweise in Kleidung eingewoben werden. Dünnschicht-Solarzellen können zwar sehr dünn gestaltet werden und werden dadurch flexibel, allerdings lassen sich diese nicht beliebig komplexen Formen anpassen, insbesondere bezogen auf Mindestradien die ein Brechen der Dünnschicht-Zellen verhindern.Compared with thin-film solar cells or conventional polycrystalines Solar cells will be presented a procedure that the presented photovoltaic by using photoactive polymers as a base with others Materials can be used or combined more easily. moreover This solar cell is more flexible and can thus be easier in complex Forms are used or woven for example in clothing become. Although thin-film solar cells can do a lot be made thin and therefore flexible, however These can not be adapted to arbitrarily complex forms, in particular based on minimum radii causing a break in the thin-film cells prevent.

Aufgrund der in der Aufgabenstellung beschriebenen Eigenschaften bestehender Photovoltaikanlagen ist der Bedarf nach einem neuen Lichtfokussierungsverfahren gegeben, das die genannten Schwierigkeiten überwindet. Zudem lässt sich das beschriebene Photovoltaiksystem besser an komplexe Formen anpassen, da es im Vergleich zu Dünnschicht-Solarzellen beliebigen Formen angepasst werden kann und keine minimalen Radien eingehalten werden müssen.by virtue of the properties described in the task Photovoltaic systems is the need for a new light focusing method given that overcomes the difficulties mentioned. In addition, the described photovoltaic system can be better to adapt to complex shapes, as compared to thin-film solar cells can be adjusted to any shape and no minimum radii must be complied with.

Der transparente Mantel kann bei Bedarf auch eingefärbt werden und dadurch optisch der Einsatzumgebung angepasst werden. Die Anzahl der Schichten zur Lichtbrechung und deren Form kann dabei nach Bedarf frei gewählt werden.The Shape of the shell and the photoactive core can be in diameter if required and in the outer shape adapted to the respective requirements be optimized, for example, for irradiation of the light from one side only. The transparent coat can at Need to be colored and thereby visually adapted to the environment of use become. The number of layers for refraction and their shape can be freely selected as needed.
Neben einer Gestaltung des Mantels aus transparentem oder gefärbt-transparentem Material lassen sich auch andere Werkstoffe in die Photovoltaikfaser integrieren. Dadurch lassen sich Materialeigenschaften wie Härte, Steifheit und andere beliebig festlegen.Next a design of the shell of transparent or colored-transparent Material can also be other materials in the photovoltaic fiber integrate.
