Description

SOLARMODUL MIT EINER MEHRLAGIGEN RÜCKSEITENFOLIE, IN DEREN  SOLAR MODULE WITH A MULTILAYER BACKPACK IN WHICH
VERKLEBUNG PIGMENTE EINGELAGERT SIND  Bonding PIGMENTS ARE STORED
Die Erfindung betrifft ein Solarmodul mit Rückseitenfolie, welche den Innenraum des Solarmoduls gegen Feuchtigkeit, zum Teil gegen ultraviolettes Licht und mechanische Einflüsse schützt und elektrisch isolierend ist, wobei die Rückseiten- folie aus wenigstens zwei unterschiedlichen Folien zusammengesetzt oder aufgebaut ist, zwischen denen sich eine Klebeschicht befindet . The invention relates to a solar module with backsheet, which protects the interior of the solar module against moisture, partially against ultraviolet light and mechanical influences and is electrically insulating, wherein the backsheet is composed of at least two different films or constructed, between which an adhesive layer is located.
Derartige Solarmodule mit Rückseitenfolien sind vielfältig, beispielsweise aus der DE 10 2008 027 000 AI, bekannt und die Rückseitenfolien haben den Vorteil, dass sie das Innere des Solarmoduls in der genannten Weise schützen und den Monteur gegen den elektrischen Strom abschirmen soll, wobei sie eine hohe Lebensdauer von beispielsweise etwa 25 Jahren haben soll, damit sie diese Schutzfunktion entsprechend lange ohne Reparatur ausüben kann und eine hohe Stromausbeute ergibt . Such solar modules with backsheets are diverse, for example from DE 10 2008 027 000 AI, known and the backsheets have the advantage that they protect the interior of the solar module in the manner mentioned and shield the fitter against the electrical current, where they have a high Life expectancy of, for example, about 25 years, so that they can perform this protective function correspondingly long without repair and results in a high current efficiency.
Dabei ist in der Regel die in Gebrauchsstellung am weitesten außen befindliche Einzelfolie oder Lage der Rückseitenfolie zum Teil gegen ultraviolettes Licht und gegen Feuchtigkeit wirksam. Die weiter innen befindliche Folie dient in der Regel zur elektrischen Isolation und kann gleichzeitig als Verbindungsfolie zu dem Einkappslungsmaterial oder der Einbettungsmasse des Solarmoduls dienen oder dazu kann eine dritte Lage oder Folie der mehrschichtigen Rückseitenfolie dienen . As a rule, the single film or the position of the backsheet located furthest outwards in the position of use is in part effective against ultraviolet light and against moisture. The film located further inside usually serves for electrical insulation and can at the same time serve as a connecting film to the Einkappslungsmaterial or the embedding mass of the solar module or to serve a third layer or film of the multilayer back sheet.
Da der übliche Aufbau von Solarmodulen einerseits relativ einfach und bekannt und somit leicht nachbaubar ist, anderer- seits aber für eine hohe Qualität eine entsprechend sorgfältige Fertigung und hochwertige Einsatzmaterialien notwendig sind, ist es immer wieder störend, wenn Plagiate solcher Solarmodule auftreten, die in ihrer Qualität minderwertig sind, aber dem Hersteller des Originals angelastet werden können . Since the usual structure of solar modules on the one hand relatively simple and well-known and thus easily replaceable, other- On the other hand, however, for a high quality a correspondingly careful production and high-quality feed materials are necessary, it is always disturbing if plagiarism of such solar modules occur, which are inferior in quality, but can be blamed on the manufacturer of the original.
Es besteht deshalb die Aufgabe, das Solarmodul so zu gestalten, dass es zerstörungsfrei identifiziert werden kann. There is therefore the task of designing the solar module so that it can be identified non-destructively.
Zur Lösung dieser Aufgabe ist bei einem Solarmodul mit Rückseitenfolie der eingangs definierten Art vorgesehen, dass in wenigstens einer Klebeschicht zwischen zwei Folien der Rückseitenfolie detektierbare Pigmente eingelagert sind. Somit kann sehr leicht festgestellt werden, dass ein Solarmodul nicht von einem bestimmten Hersteller stammt, wenn die Rückseitenfolie keine oder „falsche" detektierbare Pigmente enthält. Besonders günstig ist es, wenn die Rückseitenfolie wenigstens drei übereinander geschichtete, insbesondere unterschiedliche Einzelfolien aufweist, die jeweils zwischen sich eine Klebeschicht haben, und wenn die detektierbaren Pigmente in wenigstens einer oder in allen Klebeschichten eingelagert sind. To achieve this object, it is provided in a solar module with backsheet of the type defined above, that in at least one adhesive layer between two sheets of the backsheet detectable pigments are incorporated. Thus, it can be easily ascertained that a solar module does not originate from a specific manufacturer if the backsheet contains no or "false" detectable pigments It is particularly favorable if the backsheet has at least three individually stacked, in particular different individual films, each between have an adhesive layer, and when the detectable pigments are incorporated in at least one or all of the adhesive layers.
Ganz allgemein ist ein erheblicher Vorteil dabei darin zu sehen, dass die Pigmente in der oder den Klebeschichten angeordnet sind, sodass die unterschiedlichen Einzelfolien, aus denen die Rückseitenfolie aufgebaut ist, unverändert sein können, also ihre Teilfunktionen unverändert gut erfüllen können. Diese Einzelfolien sind also in vorteilhafter Weise pigment- oder detektionsmittelfrei , bedürfen also keiner besonderen zusätzlichen Bearbeitung. Der sehr häufige Fall einer aus drei Einzelfolien bestehenden Rückseitenfolie erlaubt also die Einlagerung der als Detek- tionsmittel dienenden Pigmente in einer oder auch in zwei Klebeschichten, um auch dadurch Unterschiede zu Plagiaten erzeugen zu können. In general, a significant advantage is the fact that the pigments are arranged in the adhesive layer (s), so that the different individual foils from which the backsheet is constructed can be unchanged, ie they can continue to perform their sub-functions well. These individual films are thus advantageously free of pigment or detection agent, so they do not require any special additional processing. The very common case of one consisting of three individual foils Backsheet thus allows the storage of the pigments used as detection means in one or in two adhesive layers in order to also be able to produce differences to plagiarisms.
Besonders vorteilhaft und zweckmäßig ist es, wenn detektier- bare Pigmente vorgesehen sind, die auf vorbestimmte vorgewählte Detektionsmittel reagieren. Dadurch kann erreicht werden, dass andere als diese vorbestimmten Detektionsmittel nicht erkannt werden und somit auch solche „unzutreffenden" Detektionsmittel enthaltende Solarmodule nicht dem Original -Hersteller zugeordnet werden. Eine besonders günstige Ausführungsform kann vorsehen, dass die in wenigstens eine Klebeschicht eingelagerten Detektionsmittel Pigmente von seltenen Erden oder von Verbindungen mit seltenen Erden sind. Derartige Detektionsmittel sind an sich bekannt, sodass sie eine entsprechend einfache Überprüfung erlauben. It is particularly advantageous and expedient if detectable pigments are provided which react to predetermined preselected detection agents. It can thereby be achieved that detection means other than these are not recognized and thus also those "incorrect" detection means containing solar modules are not assigned to the original manufacturer.A particularly favorable embodiment can provide that the embedded in at least one adhesive layer detection means pigments of rare Earths or rare earth compounds Such detection means are known per se, so that they allow a correspondingly simple verification.
Die Detektionsmittel oder Pigmente sind zweckmäßigerweise infrarot- und/oder ultraviolettempfindlich. Die Dicke der einzelnen die Rückseitenfolie bildenden unterschiedlichen Folien kann 6 bis 500 Mikrometer, vorzugsweise etwa 50 bis 250 Mikrometer betragen. Solche Foliendicken ergeben eine robuste und langlebige Rückseitenfolie. Dabei können die die Rückseitenfolie bildenden unterschiedlichen Einzelfolien alle verschiedene Kunststofffolien oder aber Kunststofffolien und eine Aluminiumfolie sein. The detection means or pigments are expediently infrared and / or ultraviolet sensitive. The thickness of each of the different backsheet forming films may be from 6 to 500 microns, preferably from about 50 to 250 microns. Such film thicknesses provide a robust and durable backsheet. In this case, the different individual films forming the backsheet can all be different plastic films or else plastic films and an aluminum foil.
Vor allem bei Kombination einzelner oder mehrerer der vorbe- schriebenen Merkmale und Maßnahmen ergibt sich ein Solarmo- dul, dessen Rückseitenfolie zwar aus üblichen unveränderten Einzelfolien aufgebaut sein kann, die aber innerhalb der oder den Klebeschichten beigemischte Stoffe als Detektionsmittel , insbesondere Pigmente von seltenen Erden oder von Oxiden von seltenen Erden enthält. Especially when combining one or more of the above-described features and measures, a solar energy system results. dul, whose backsheet may indeed be constructed from conventional unmodified individual foils, but contains within the or the adhesive layers admixed substances as a detection agent, in particular pigments of rare earths or of oxides of rare earths.
Beispielsweise kann es sich um Sicherheitspigmente handeln, wie sie in DE 10 2007 058 601 AI als Stand der Technik und/oder als Neuerung beschrieben sind. For example, they may be security pigments, as described in DE 10 2007 058 601 AI as state of the art and / or as innovation.
