Photovoltaic solar generators whose solar cells are arranged in shingle technique, apply in the art generally known. Die Schindelstrings liegen beispiels weise in Schmelzkleberfolien eingebettet zwischen einem Träger aus beispielsweise Glas oder Metall, vorzugsweise Aluminium, und einer Abdeckung, insbesondere aus Glas. The shingle strings lie example, in hot-melt adhesive films embedded between a carrier of, for example glass or metal, preferably aluminum, and a cover, in particular made of glass.

Die Herstellung derartiger Solargeneratoren kann beispiels weise dadurch erfolgen, daß die Schindelstrings durch Auf einanderlegen der die Kontaktanschlüsse enthaltenden Längs kanten der Solarzellen und durch anschließendes Kleben oder Löten der Kontaktanschlüsse jeweils der benachbarten Solar zellen hergestellt werden. The preparation of such solar generators can be done example that the shingle strings are produced by superposing on the contact terminals comprising longitudinal edges of the solar cells and by subsequently gluing or soldering of the contact terminals in each of the adjacent solar cells thereby. Bei den Kontakten kann es sich um im Siebdruckverfahren aufgebrachte oder um in Vakuumtechnik aufgedampfte Mehrschicht-Metallkontakte handeln, die einen Anschlußbalken oder Anschlußbereiche an einer Längskante der Solarzelle aufweisen. The contacts may be applied by screen printing or to act vapor-deposited multi-layer metal contacts in vacuum technology, which have a terminal bars or terminal areas on a longitudinal edge of the solar cell. Anschließend werden die Schindel strings untereinander verschaltet, mit elektrischen An schlüssen versehen und in den Schmelzkleberfolien eingebet tet. Then the shingle strings are connected to each other, equipped with electric-circuits on and eingebet in the hot-melt adhesive films tet. Der mit einer Abdeckung und einem Träger versehene Generatorverbund wird abschließend in einem Vakuum-Verbund prozeß zu dem photovoltaischen Solargenerator laminiert. The provided with a cover and a composite carrier generator is finally process in a vacuum composite laminated to the photovoltaic solar generator. Es hat sich bei den beschriebenen Solargeneratoren herausge stellt, daß im Bereich der Kontaktverbindungen durch Tempe raturwechsel-Kräfte im Generatormodul nachteiligerweise Zel lenbrüche aufgetreten sind, insbesondere bei einer Rücksei tenabdeckung aus Aluminium. It has also provides herausge in the described solar generators that disadvantageously in the region of the contact connections by Tempe raturwechsel forces in the generator module Zel lenbrüche have occurred, especially in a back print panel fascia made of aluminum.

Der Erfindung liegt daher die Aufgabe zugrunde, einen So largenerator der eingangs genannten Art zu schaffen, bei dem ein Bruch der Solarzellen nach Herstellung des Solar generators aufgrund von Temperaturwechsel-Kräften vermieden wird. The invention is therefore based on the object, a Sun of the type mentioned largenerator to create, in which a fraction of the solar cells to produce the solar generator is avoided due to temperature change forces.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß räum lich zwischen den elektrisch leitend zu verbindenen Kontakt anschlußbalken oder Kontaktinsel der Solarzellen Zwischenverbinder angeordnet sind. The object is inventively achieved in that cavities Lich connecting bar between the electrically conductive to be connected contact or contact pad of the solar cell interconnector are arranged.

Durch den erfindungsgemäßen Zwischenverbinder werden infolge der besonderen Formgebung der elastischen Verbindungsstege die Temperaturwechselkräfte sehr gut aufgenommen, so daß Zug- oder Druckkräfte nicht in den Kristrallbereich der So larzelle eingeleitet werden können. The inventive interconnector thermal shock forces are very well received, so that tensile or compressive forces can not be introduced into the Kristrallbereich the Sun larzelle due to the special shape of the elastic connecting webs.

Die durch die Schindeltechnik erzielbare optimale Flächen ausnutzung im Generator infolge des Wegfalls von Zwischen räumen zwischen den Zellen, sowie die Überdeckung von Kon taktflächen durch aktive Zellenflächen bleibt vorteilhaf terweise voll erhalten. The achievable by the shingle technique optimum space utilization in the generator due to the elimination of gaps between the cells, as well as the overlap of con tact surfaces by active cell areas is fully maintained is advantageously at.
