"Vorzugsweise als Fassaden- oder als Dachbauelement verwendbarer Solargenerator""Solar generator that can be used primarily as a facade or roof element"

Die Neuerung betrifft einen vorzugsweise als Fassadenoder als Dachbauelement im undurchsichtigen Gebäudebereich verwendbaren Solargenerator bestehend aus zwischen zwei Schmelzkleberfolien gelegten miteinander verschalteten Solarzellen und aus zwei jeweils eine Schmelzkleberfolie abdeckende Schutzabdeckungen vorzusweise aus Glas.The innovation concerns a solar generator that can be used preferably as a facade or roof element in opaque building areas, consisting of interconnected solar cells placed between two hot-melt adhesive films and two protective covers, preferably made of glass, each covering a hot-melt adhesive film.

Derartige Solargeneratoren, die auch als photovoltaische Fassadenelemente bezeichnet werden und beispielsweise in einem Prospekt der Firma Schüco/Bielefeld beschrieben sind, dienen neben dem Planen und Gestalten von Fassaden vor allem auch als Energiequellen. Diese Solargeneratoren, deren erzeugte elektrische Energie vorteilhafterweise über Wechselrichter in das Netz eingespeist wird, können in ihrem Randbereich in der Ebene der Solarzellen zusätzlicheSuch solar generators, which are also referred to as photovoltaic facade elements and are described, for example, in a brochure from Schüco/Bielefeld, are used not only for planning and designing facades, but also as energy sources. These solar generators, whose electrical energy is advantageously fed into the grid via inverters, can generate additional energy in their peripheral area in the plane of the solar cells.

Schmelzkleberfolienstreifen zwischen den Schmelzkleberfolien aufweisen. Ein Verfahren zur Herstellung derartiger Solargeneratoren ist in der DE 32 39 676 Al beschrieben.Hot melt adhesive film strips between the hot melt adhesive films. A method for producing such solar generators is described in DE 32 39 676 A1.

Bei der Verwendung der bekannten photovoltaischen Fassadenelementen ist es nachteilig, daß aufgrund der unter-When using the known photovoltaic facade elements it is disadvantageous that due to the different

- 2 - HH 93/09- 2 - HH93/09

schiedlichen Farbtönungen von Solarzellen, durchsichtigen Schmelzkleberteile und der auch nach Anbringung der Fassadenbauelemente sichtbaren Fassadenteile ein farblich unterschiedliches Erscheinungsbild der Gesamtfassade entsteht. Different color tones of solar cells, transparent hot melt adhesive parts and the facade parts that are visible even after the facade components have been attached create a different color appearance of the overall facade.

Der Neuerung liegt daher die Aufgabe zugrunde, einen Solargenerator der eingangs genannten Art zu schaffen, durch den ein einheitliches und damit homogenes äußeres Farbbild der Gesamtfassade sichergestellt wird.The innovation is therefore based on the task of creating a solar generator of the type mentioned above, which ensures a uniform and thus homogeneous external color image of the entire facade.

Die Aufgabe wird neuerungsgemäß dadurch gelöst, daß die lichtseitenabgewandte Schmelzkleberfolie eine Farbpigmentierung enthält, die auf der Lichteinfallsoberfläche den durch die Solarzellen unbedeckten Teilen des Solargenerators eine der Farbe der Solarzellen angepaßte Farbtönung verleiht.The task is solved according to the innovation in that the hot melt adhesive film facing away from the light side contains a color pigmentation which gives the parts of the solar generator uncovered by the solar cells a color tone on the light-incident surface that matches the color of the solar cells.

Ausgestaltungen der Neuerung sind in den Unteransprüchen beschrieben.Embodiments of the innovation are described in the subclaims.

Ein wesentlicher Vorteil der Neuerung liegt in dem optisch-ästhetischen Eindruck einer Glasfassade, der einem Betrachter vermittelt wird. Fassadenbauelemente wie Träger, Betonvorsprünge oder Isolierungselemente werden durch die als Brüstungsbauelemente anzusehenden Solargeneratoren vorteilhafterweise verdeckt. Die Verwendung der neuerungsgemäßen Solargeneratoren ist allerdings nicht auf Fassaden- oder Dachbauelement beschränkt, sondern sie können überall dort eingesetzt werden, wo es auf einen optischästhetischen Gesamteindruck ankommt, z. B. bei der Verwendung als Solargenerator-Schiebedach für Personenkraftwagen. A key advantage of the innovation is the optical-aesthetic impression that a glass facade conveys to the viewer. Facade construction elements such as supports, concrete projections or insulation elements are advantageously concealed by the solar generators, which are seen as parapet construction elements. The use of the solar generators according to the innovation is not limited to facade or roof construction elements, however, but can be used anywhere where an optical-aesthetic overall impression is important, e.g. when used as a solar generator sunroof for passenger cars.

In der Zeichnung ist ein Ausführungsbeispiel nach der Neuerung dargestellt, und zwar zeigen:The drawing shows an embodiment of the innovation, namely:

Fig. 1 die Bauelemente eines teilweise gezeichneten Solargenerators im unverklebten Zustand, und Fig. 2 den Solargenerator gemäß Fig. 1 im verklebtenFig. 1 the components of a partially drawn solar generator in the unglued state, and Fig. 2 the solar generator according to Fig. 1 in the glued state

Zustand.Condition.

Gemäß Fig. 1 sind zwischen einer oberen Glasplatte 2, die als Schutzabdeckungen dienen, eine obere und untere Schmelzkleberfolie 3 bzw. 4 mit dazwischen liegenden miteinander verschalteten Solarzellen 5 angeordnet. Zusätzlich sind im Randbereich des Solargenerators in der Ebene der Solarzellen 5 Schmelzkleberfolienstreifen 6 vorgesehen, die etwa die Dicke der Solarzellen 5 besitzen und aus fertigungstechnischen Gründen die zusammengeschalteten Solarzellen 5 allseitig umschließen. Es sind jedoch auch Fertigungsverfahren bekannt, bei denen die Verwendung der zusätzlichen Randstreifen nicht unbedingt erforderlich sind. Wesentlicher Bestandteil der Fertigungsverfahren zur Herstellung eines in Fig. 2 dargestellten Solargenerators ist eine Temperatur-/Druckbehandlung des lose zusammengesetzten Verbundes gemäß Fig. 1, beispielsweise mittels eines Autoklav-Verfahrens.According to Fig. 1, an upper and lower hot-melt adhesive film 3 and 4 are arranged between an upper glass plate 2, which serve as protective covers, with interconnected solar cells 5 lying between them. In addition, hot-melt adhesive film strips 6 are provided in the edge area of the solar generator in the plane of the solar cells 5, which have approximately the thickness of the solar cells 5 and, for manufacturing reasons, enclose the interconnected solar cells 5 on all sides. However, manufacturing processes are also known in which the use of the additional edge strips is not absolutely necessary. An essential component of the manufacturing process for producing a solar generator shown in Fig. 2 is a temperature/pressure treatment of the loosely assembled composite according to Fig. 1, for example using an autoclave process.

Die untere Schmelzkleberfolie 4, die sich auf der lichtabgewandten Seite des Solargenerators befindet, weist eine Farbpigmentierung auf, die den durch die Solarzellen 5 unbedeckten Teilen des Solargenerators eine der Farbe der Solarzellen 5 angepaßte Farbtönung verleiht.The lower hot-melt adhesive film 4, which is located on the side of the solar generator facing away from the light, has a color pigmentation that gives the parts of the solar generator uncovered by the solar cells 5 a color tone that matches the color of the solar cells 5.

Beispielsweise kann diese Schmelzkleberfolie 4 - zu grauen, blauen oder schwarzen Solarzellen 5 passend - schwarz ausgeführt sein.For example, this hot melt adhesive film 4 can be black - to match grey, blue or black solar cells 5.

- 4 - HH 93/09- 4 - HH93/09

Zur weitern Verbesserung des optisch-ästhetischen Gesamteindruckes des Solargenerators können auch die Randstreifen 6 und/oder Teile der oberen Schmelzkleberfolie 3, die die Solarzellen 5 nicht bedecken, zusätzlich eine der Farbe der Solarzellen 5 angepaßte Farbtönung aufweisen.To further improve the overall optical-aesthetic impression of the solar generator, the edge strips 6 and/or parts of the upper hot-melt adhesive film 3, which do not cover the solar cells 5, can also have a color tone that matches the color of the solar cells 5.
