Die Erfindung betrifft ein photovoltaisches Solarmodul in Plattenform, insbesondere zur Verwendung als Dach-, Fassaden- oder Fensterelement, mit mindestens einer dem Licht zugewandten transparenten Außenscheibe, einer Abschlussplatte (z.B. Tedlarfolie oder transparente Scheibe) und dazwischen angeordnet, in Verbundfolie, Gießharz oder ähnlichem eingebetteten Solarzellen, weiche mit Leiterbahnen elektrisch miteinander verschaltet werden.The The invention relates to a photovoltaic solar module in panel form, especially for use as a roof, façade or window element, with at least one transparent outer pane facing the light, an end plate (e.g., Tedlar foil or transparent disc) and interposed therebetween, in composite foil, cast resin or similar embedded solar cells, soft with interconnects are electrically interconnected.

Die Nutzung von alternativen Energieträgern wie Wind, Wasser, Biomasse und Sonne gewinnt angesichts weltweit steigendem Energiebedarf und den begrenzten und endlichen Ressourcen an konventionellen Energieträgern wie Erdöl, Kohle und Erdgas immer mehr an Bedeutung. Einer zügigen Anwendung der alternativen Energieträger stehen bisweilen relativ hohe Produktionskosten entgegen. Durch den steigenden Bedarf an Strom aus Sonnenenergie setzt die Industrie immer mehr auf automatisierte Herstellung der Solarmodule, gleichzeitig sinken die Produktionskosten und ermöglichen so eine raschere Verbreitung und Akzeptanz der Sonnenenergie.The Use of alternative energy sources such as wind, water, biomass and sun is gaining in the face of increasing global energy demand and the limited and finite resources of conventional energy sources such as Oil, Coal and natural gas are becoming increasingly important. A speedy application the alternative energy source sometimes counteract relatively high production costs. By the growing demand for electricity from solar energy is set by the industry more and more on automated production of solar modules, at the same time decrease production costs and thus enable a faster spread and acceptance of solar energy.

Es ist bekannt, dass bei Solarmodulen die Zellenstrings mittels Lötbänder elektrisch leltend verbunden werden. Diese Lötbänder werden entsprechend der benötigten Länge abgeschnitten und entweder manuell von Hand oder automatisch über Greifer zugeführt und mit den Anschlussbändern der Zellenstrings verlötet oder verschweißt. Dieser Vorgang ist zeitaufwändig und besonders bei der manuellen Verlötung fehlerbehaftet und führt oftmals auch zu optischen Mängeln im Aussehen der fertigen Zellmatrix und somit auch beim fertigen Solarmodul.It It is known that in solar modules, the cell strings by means of solder strips electrically be connected. These bracelets are according to the required Length cut off and either manually fed by hand or automatically via gripper and with the connection tapes the cell strings soldered or welded. This process is time consuming and especially with the manual soldering faulty and often leads also to optical defects in the appearance of the finished cell matrix and thus also in the finished Solar module.

Aufgabe der vorliegenden Erfindung ist es, ein Solarmodul zur Verfügung zu stellen, welches die oben beschriebenen Mängel nicht aufweist.task The present invention is to provide a solar module available which does not have the deficiencies described above.

Diese Aufgabe wird mit einem Solarmodul nach Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.These The object is achieved with a solar module according to claim 1. advantageous Embodiments are the subject of the dependent claims.

Erfindungsgemäß ist vorgesehen, dass die Querverschaltung der Solarzellenstrings mittels Leiterbahnen erfolgt, welche auf einem geeigneten Trägermaterial aufgebracht wurden. Hierbei werden die Leiterbahnen mit Abstand parallel zueinander angeordnet. Durch diesen definierten Abstand sind die Leiterbahnen elektrisch gegeneinander isoliert. Die Querverschaltungen werden als vorgefertigte Streifen in einem definierten Abstand ausgelegt und die Zellmatrix aufgelegt und mit den Leiterbahnen der Querverschaltung dauerhaft elektrisch leitend verbunden. Die Leiterbahnen sind so angebracht bzw. ausgeführt, dass die Stringkontaktierung gleichmäßig gekürzt werden kann. Daraus resultiert in der Praxis ein Produktionsvorteil. Diese Querverschaltungen können entsprechend den Anforderungen des jeweiligen Solarmoduls ausgebildet werden. Insbesondere können die Anschlussfahnen für die elektrische Anschlussdose mit integriert werden, ebenso wie Lötaugen oder andere für die dauerhafte Kontaktierung der Anschlusseinrichtungen erforderliche Kontaktflächen.According to the invention, it is provided that the cross-connection of the solar cell strings by means of conductor tracks takes place, which were applied to a suitable carrier material. In this case, the interconnects are at a distance parallel to each other arranged. Through this defined distance are the tracks electrically isolated from each other. The cross-connections become designed as prefabricated strips at a defined distance and the cell matrix placed on top and with the tracks of the cross-connection permanently electrically connected. The tracks are like that attached or executed, that the string contact can be shortened evenly. This results in practice a production advantage. These cross-connections can be made accordingly Be formed the requirements of each solar module. In particular, you can the connection lugs for the electrical junction box can be integrated with, as well pads or others for the permanent contact of the connection devices required Contact surfaces.

Die Anschlussfahnen können durch einen Einschnitt in den rückseitigen Folien oder bei Glas-in-Glas-Bauweise (Fensterelement) zwischen den Scheiben herausgeführt werden. Dieser Einschnitt wird beim laminieren wieder verschlossen und beeinträchtigt die Funktion des Laminatverbundes nicht. Nach dem laminieren wird dann die Anschlussdose aufgebracht und mit den Anschlussfahnen verbunden. Hierzu ist die Anschlussfahne flexibel ausgeführt und kann um bis zu 184° gebogen werden. Mit der Erfindung können alle auf dem Markt üblichen Solarmodule mit ihren spezifischen Anschlussarten hergestellt werden. Die Querverschaltung kann in Größe und Ausführung an jedes Solarmodul angepasst werden.The Connection flags can through an incision in the back Foils or in glass-in-glass construction (window element) between the Slices brought out become. This incision is closed again during lamination and impaired the function of the laminate composite not. After laminating becomes then the junction box is applied and connected to the terminal lugs. For this purpose, the connection lug is flexible and can be bent by up to 184 ° become. With the invention can all solar modules commonly used on the market be manufactured with their specific connection types. The cross-connection may vary in size and finish each solar module can be customized.

Die Zellenstrings werden mit der in der Zwischenschicht eingebetteten Querverschaltung mittels löten oder schweißen, dauerhaft elektrisch leitend verbunden. Fertigungstechnisch von Vorteil ist, dass die Querverschaltung industriell hergestellt werden kann. Die Querverschaltung kann sowohl in der manuellen als auch in der automatischen Herstellung von Solarmodulen eingesetzt werden.The Cell strings are embedded with the one in the interlayer Cross connection by means of soldering or welding, permanently electrically connected. Manufacturing technology of The advantage is that the cross-connection can be manufactured industrially. The cross connection can be used both in the manual and in the automatic production of solar modules can be used.
