Abstract

Solar energy powered generator uses a number of cells which in cross section have a hexagonal shape allowing stacking together without intervening spaces between adjacent cells. Pref. the hexagon shapes are regular with all the sideds of equal length. Typically silicon cells are used which in comparison to quadratic shaped cells of the same composition have approx. 53% less waste.

Description

SolargeneratorSolar generator

Die Erfindung betrifft einen Solargenerator aus Solarzellen, die in einer Fläche mit weiteren Solarzellen gleicher Abmessungen zusammenschaltbar sind.The invention relates to a solar generator made of solar cells, which are shown in an area can be interconnected with other solar cells of the same dimensions.

Bei einem bekannten Solargenerator (vergleiche die Zeitschrift "Der Elektroniker", Heft 12, 1978, Seite 15) sind mehrere kreisrunde Solarzellen in Silikonkautschuk eingebettet und mit einer Glasfaserplatte als Frontabdeckung versehen. Die mechanische Stabilität wird diesem Solargenerator durch einen metallischen Rahmen verliehen.With a well-known solar generator (compare the magazine "Der Electronics ", No. 12, 1978, page 15) are several circular solar cells in silicone rubber embedded and provided with a fiberglass plate as a front cover. The mechanical A metallic frame gives this solar generator stability.

Für die Herstellung von Solargeneratoren ist es von Bedeutung, für eine wirtschaftliche Flächenausnutzung eine möglichst dichte Anordnung der Solarzellen selbst zu erreichen.For the manufacture of solar generators it is important for an economical use of space an arrangement of the solar cells as dense as possible reach yourself.

Aus Silicium bestehende Solarzellen werden bisher in runder (vergleiche die obige Literaturstelle) oder vier- eckiger Form hergestellt, wobei aber nur durch die viereckige Form eine geschlossene Anordnung in einer Fläche möglich ist. Da aber viereckige Siliciumscheiben aus runden Siliciumscheiben vorher herausgeschnitten werden müssen, ist in diesem Fall der nicht verwendbare Anteil der Siliciumscheiben erheblich.Solar cells made of silicon have so far been made more rounded (cf. the above reference) or four- square shape made, but only because of the square shape a closed arrangement in a surface is possible. But there were square silicon wafers made from round silicon wafers before need to be cut out is the unusable portion in this case the silicon wafers considerably.

Es ist daher Aufgabe der Erfindung, einen Solargenerator aus Solarzellen anzugeben, der bei optimaler Flächenausnutzung einen möglichst geringen Abfall an Silicium erforderlich macht.It is therefore the object of the invention to provide a solar generator made from solar cells indicate that with optimal use of space, the lowest possible waste Requires silicon.

Diese Aufgabe wird bei einem Solargenerator der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß die Kante der Solarzelle die Gestalt eines Sechsecks be sitzt, so daß eine geschlossene Belegung der Fläche ohne Zwischenräume möglich ist.In the case of a solar generator, this task becomes the one mentioned at the beginning Type solved according to the invention in that the edge of the solar cell has the shape of a Hexagon be seated, so that a closed occupancy of the area without gaps is possible.

Die Erfindung sieht also anstelle rechteckiger oder runder Solarzellen sechseckige Solarzellen vor, die mit einem erheblich geringeren Siliciiimabfall aus runden Scheiben herausgeschnitten werden können und außerdem eine flächendeckende, geschlossene Anordnung ermöglichen.The invention therefore sees instead of rectangular or round solar cells hexagonal solar cells with a considerably lower silicon waste can be cut out of round slices and also a comprehensive, enable closed arrangement.

Anstelle regelmäßiger sechseckiger Solarzellen könnten gegebenenfalls auch regelmäßige achteckige Solarzellen verwendet werden, wobei dann allerdings die entstehenden Zwischenräume ftir eine geschlossene Flächendekung mit kleineren quadratischen Solarzellen zu versehen wären.Instead of regular hexagonal solar cells, regular octagonal solar cells can also be used, although then the resulting interspaces for a closed surface with smaller ones square solar cells would have to be provided.

Eine einfache mathematische Rechnung zeigt, daß bei sechseckigen Solarzellen gegenüber quadratischen Solarzellen etwa 53 % weniger Abfall auftritt, während bei achteckigen Solarzellen mit kleinen quadratischen Solarzellen die Einsparung an Abfall gegenüber quadratischen Solarzellen lediglich 43 % beträgt.A simple mathematical calculation shows that with hexagonal solar cells about 53% less waste occurs compared to square solar cells, while with octagonal Solar cells with small square solar cells compared to the saving in waste square solar cells is only 43%.

Nachfolgend wird die Erfindung an Hand der Zeichnung näher erläutert, in deren einziger Figur eine Anordnung regelmäßiger sechseckiger Solarzellen gezeigt ist.The invention is explained in more detail below with reference to the drawing, in the single figure an arrangement of regular hexagonal solar cells is shown is.

Die Figur zeigt einen Solargenerator 3 aus mehreren Solarzellen 1, die jeweils gleiche geometrische Abmessungen besitzen und mit ihren Kanten 2 Sechsecke bilden.The figure shows a solar generator 3 composed of several solar cells 1, each have the same geometric dimensions and have 2 hexagons with their edges form.

Diese Solarzellen 1 ermöglichen eine geschlossene Belegung einer Fläche ohne Zwischenräume und somit eine optimale Flächenausnutzung bei nur geringem Abfall, der beim Schneiden der Solarzellen 1 aus einer kreisförmigen Scheibe entsteht.These solar cells 1 enable a closed occupancy of an area without gaps and thus an optimal use of space with only little waste, which is created when the solar cells 1 are cut from a circular disk.
