Die Erfindung betrifft eine photovoltaische Platte zur direkten Umwandlung von Sonnenlicht in elektrische Energie, die insbesondere zum Einsatz als Fassadenplatte geeignet sein soll.The invention relates to a photovoltaic panel for the direct conversion of sunlight into electrical energy, which is particularly suitable for use as a facade panel.
Herkömmliche photovoltaische Platten bestehen aus mindestens einem Solarmodul mit einer oder mehreren Solarzellen, wobei die photosensitive Halbleiterschicht und entsprechende Anschlußkontakte der Solarzellen auf einer ggfls. gemeinsamen Trägerplatte des Moduls aufgebracht sind. Zur Realisierung einer photovoltaischen Platte, wie sie als sogenanntes Solarpaneel beispielsweise auf Dächern von Häusern, Camping-Fahrzeugen oder Wohnwagen montiert sind, werden in der Regel mehrere solcher Solarmodule mit ihrer Trägerseite auf einer gemeinsamen Halteplatte befestigt und die photosensitive Halbleiterschicht beispielsweise durch eine transparente Giesharzschicht abgedeckt, um so eine praktisch handhabbare und vor Umwelteinflüssen geschützte Einheit zu erhalten.Conventional photovoltaic panels consist of at least one solar module with one or more solar cells, whereby the photosensitive semiconductor layer and the corresponding connection contacts of the solar cells are applied to a common carrier plate of the module if necessary. To create a photovoltaic panel, such as those mounted as a so-called solar panel on the roofs of houses, camping vehicles or caravans, several such solar modules are usually attached with their carrier side to a common holding plate and the photosensitive semiconductor layer is covered, for example, by a transparent cast resin layer, in order to obtain a unit that is easy to handle and protected from environmental influences.
Alternativ dazu ist es auch bekannt, als gemeinsame Halteplatte und Schutzabdeckung für eine Vielzahl von kleinflächigen Solarmodulen eine Glasscheibe zu verwenden, mit der die Solarmodule über ihre photosensitive Schicht verbunden sind.Alternatively, it is also known to use a glass pane as a common holding plate and protective cover for a large number of small-area solar modules, to which the solar modules are connected via their photosensitive layer.
Die bekannten photovoltaischen Platten weisen verschiedene Nachteile auf. So sind sie gegenüber Umwelteinflüssen und mechanischen Beanspruchun-The known photovoltaic panels have various disadvantages. They are sensitive to environmental influences and mechanical stress.
gen, wie sie insbesondere bei der Montage auf Haus-, Fahrzeugdächern oder als Fassadenverkleidungen auftreten, nur ungenügend geschützt. Darüberhinaus bedarf es bei der Fertigung großflächiger Platten eines hohen Herstellungsaufwandes., which occur particularly when installed on house or vehicle roofs or as facade cladding, are only inadequately protected. In addition, the production of large-area panels requires a high level of manufacturing effort.
Der Erfindung liegt die Aufgabe zugrunde, eine photovoltaische Platte zu schaffen, die robust und damit einfach handhabbar, besonders gegen Umwelteinflüsse geschützt und rationell herstellbar ist.The invention is based on the object of creating a photovoltaic panel which is robust and thus easy to handle, particularly protected against environmental influences and can be produced efficiently.
Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst. Demnach ist die photovoltaische Platte in einer Weise herstellbar, wie sie von der Herstellung von Verbundglasscheiben bestens bekannt und in verfahrenstechnischer Hinsicht besonders ausgereift ist. Durch den kompletten Einschluß des mindestens einen Solarmoduls zwischen einer vorder- und einer rückseitigen Glasscheibe sind die Verbundplatte und insbesondere die photosensitiven Halbleiterschichten hervorragend gegen Umwelteinflüsse geschützt. Damit ist die erfindungsgemäße photovoltaische Platte in besonderen Weise zum Einsatz als Fassadenplatte geeignet. Dazu trägt auch der stabile Aufbau der Platte in Form einer dreitägigen Verbundkonstruktion bei.This object is achieved by the features specified in claim 1. Accordingly, the photovoltaic panel can be manufactured in a manner that is well known from the manufacture of laminated glass panes and is particularly sophisticated in terms of process technology. Due to the complete enclosure of the at least one solar module between a front and a rear glass pane, the composite panel and in particular the photosensitive semiconductor layers are excellently protected against environmental influences. The photovoltaic panel according to the invention is therefore particularly suitable for use as a facade panel. The stable structure of the panel in the form of a three-day composite construction also contributes to this.
Durch die im Anspruch 2 angegebene Maßnahme werden verschiedene Vorteile erzielt. Da das mindestens eine Solarmodul als Trägerplatte eine Glasscheibe aufweist, besteht die gesamte erfindungsgemäße Platte im wesentlichen aus drei Glasscheiben, die beispielsweise auf Temperaturschwankungen gleichermaßen reagieren. Es kann damit nicht zu thermisch bedingten Spannungen innerhalb des Verbundes kommen. Darüberhinaus weisen Solarmodule mit einer amorphen photovoltaisch wirksamen Beschichtung den Vorteil auf, daß sie bezüglich ihrer in Richtung der Anschlußkontaktstreifen weisenden Länge praktisch beliebig kürzbar sind. Damit können auf der Basis des Erfindungsgegenstandes Fassadenplatten hergestellt werden, die zumindest in einer Richtung eine beliebige Länge aufweisen und optimal an die baulichen Gegebenheiten des zu verkleidenden Bauwerkes angepaßt werden können.Various advantages are achieved by the measure specified in claim 2. Since the at least one solar module has a glass pane as a carrier plate, the entire plate according to the invention essentially consists of three glass panes, which react equally to temperature fluctuations, for example. This means that thermally induced stresses cannot arise within the composite. In addition, solar modules with an amorphous photovoltaically effective coating have the advantage that their length in the direction of the connection contact strips can be shortened to practically any length. This means that facade panels can be produced on the basis of the subject matter of the invention that have any length in at least one direction and can be optimally adapted to the structural conditions of the building to be clad.
Durch die Ausgestaltung der photovoltaischen Platte nach Anspruch 3 wird einerseits der Schutz vor Umwelteinflüssen weiter verbessert. Andererseits wird durch die über die außenseitigen Randkanten des mindestens einen Solarmoduls überstehenden Randbereiche der beiden Glasscheiben ein umlaufender Rand gebildet, an dem eine Rahmen-Haltekonstruktion für die Platte angreifen kann, ohne daß diese einen Teil der photosensitiven Fläche des oder der Solarmodule abdeckt. Eine solche Abdeckung ist nämlich zu vermeiden, da Messungen gezeigt haben, daß ein Abdecken des Randbereiches einer Solarzelle eine deutlich meßbare Leistungsminderung der Zelle zur Folge hat.The design of the photovoltaic plate according to claim 3 further improves protection against environmental influences. On the other hand, the edge regions of the two glass panes that protrude beyond the outer edge of the at least one solar module form a peripheral edge to which a frame support structure for the plate can attach without covering part of the photosensitive surface of the solar module or modules. Such a covering should be avoided because measurements have shown that covering the edge region of a solar cell results in a clearly measurable reduction in the cell's performance.
Durch die im Anspruch 4 angegebene Maßnahme wird eine erhebliche Fertigungsvereinfachung erzielt, da als Dichtungsmasse für die Randfuge der Platte das ohnehin vorhandene Material der über die außenseitigen Randkanten des mindestens einen Solarmoduls überstehenden und während des Verbundprozesses erweichenden Verbundfolienlagen verwendet wird.The measure specified in claim 4 achieves a significant simplification of production, since the material already present in the composite film layers protruding beyond the outer edge of the at least one solar module and softening during the bonding process is used as the sealing compound for the edge joint of the panel.
Durch die im Anspruch 5 angegebene Einbettung der elektrischen Anschlüsse des mindestens einen Solarmoduls und der diesen zugeordneten Anschlußkabel werden die gegen Korrosion besonders empfindlichen Kontaktstellen besonders wirkungsvoll vor Umwelteinflüssen und insbesondere Feuchtigkeit geschützt. Die Ansprüche 6 und 7 lehren dabei eine besonders raumsparende und praxisgerechte Anordnung der Anschlußkontakte des mindestens einen Solarmoduls und der Anschlußkabel der erfindungsgemäßen photovoltaischen Platte.By embedding the electrical connections of the at least one solar module and the connecting cables associated with them as specified in claim 5, the contact points, which are particularly sensitive to corrosion, are particularly effectively protected from environmental influences and in particular moisture. Claims 6 and 7 teach a particularly space-saving and practical arrangement of the connection contacts of the at least one solar module and the connecting cables of the photovoltaic plate according to the invention.
Durch die Ausgestaltung der photovoltaischen Platte nach den Ansprüchen 8 bzw. 9 wird der ästhetische Gesamteindruck, den die Platte vermittelt, stark verbessert. Durch die angegebenen Maßnahmen erhalten nämlich auch die nicht von einem Solarmodul unterlegten Bereiche der äußeren Glasscheibe eine Oberflächenbeschaffenheit - also Farbgebung und Struktur -, die der des Solarmoduls entspricht. Die erfindungsgemäße Platte hat also ein durchgehendes, einheitliches Erscheinungsbild, was im Zuge der hohen architektonischen Anforderungen an im Fassadenbau verwendeteThe design of the photovoltaic panel according to claims 8 and 9 significantly improves the overall aesthetic impression that the panel conveys. The measures specified also give the areas of the outer glass pane that are not supported by a solar module a surface finish - i.e. color and structure - that corresponds to that of the solar module. The panel according to the invention therefore has a consistent, uniform appearance, which is a good result of the high architectural requirements for the panels used in facade construction.
Platten besonders vorteilhaft ist. Dabei kommt auch zum Tragen, daß durch die Beschichtung in den Randbereichen der äußeren Glasscheibe die Anschlußkontakte des oder der Solarmodule vollständig abgedeckt werden.Plates is particularly advantageous. It is also important to note that the coating in the edge areas of the outer glass pane completely covers the connection contacts of the solar module(s).

Fig. 3 eine Teildraufsicht auf den Eckbereich einer Platte gemäß Fig. 1.Fig. 3 is a partial plan view of the corner area of a panel according to Fig. 1.
Eine erfindungsgemäße photovoltaische Platte weist vorderseitig eine 4 mm dicke Glasscheibe 1 und rückseitig eine ebensolche Glasscheibe 2. Beide rechteckförmigen Glasscheiben 1,2 sind aus vorgespannten Einscheibensicherheitsglas gefertigt.A photovoltaic panel according to the invention has a 4 mm thick glass pane 1 on the front and a glass pane 2 of the same thickness on the back. Both rectangular glass panes 1, 2 are made of toughened single-pane safety glass.
Zwischen den beiden Glasscheiben 1, 2 sind drei handelsübliche, langgestreckt rechteckige Solarmodule 3 eingeschlossen, die in einer gemeinsamen Ebene E mit ihren Längsseiten 4, 4' über eine Stoßfuge 5 beabstandet aneinandergereiht sind. In den Zeichnungen ist der detaillierte Aufbau der Solarmodule 3 nicht näher dargestellt. Sie bestehen aus einer Trägerplatte aus Floatglas mit einer Dicke von 2 mm, auf die eine photosensitive amorphe Halbleiterbeschichtung aufgebracht ist. Entlang der beiden Längsseiten 4, 4' der Solarmodule 3 verlaufen jeweils metallische Kontaktstreifen 6,6' die im Bereich einer der beiden Querseiten 7, 7' der Solarmodule 3 jeweils mit einer Anschlußlötfahne 8, 8' versehen sind. Jedes Solarmodul stellt eine maximale elektrische Leistung von 25 Watt zurThree commercially available, elongated rectangular solar modules 3 are enclosed between the two glass panes 1, 2, which are lined up in a common plane E with their long sides 4, 4' spaced apart by a butt joint 5. The detailed structure of the solar modules 3 is not shown in detail in the drawings. They consist of a carrier plate made of float glass with a thickness of 2 mm, to which a photosensitive amorphous semiconductor coating is applied. Metallic contact strips 6, 6' run along the two long sides 4, 4' of the solar modules 3, each of which is provided with a connection soldering lug 8, 8' in the area of one of the two transverse sides 7, 7' of the solar modules 3. Each solar module provides a maximum electrical output of 25 watts.
Verfügung. Es ist im Handel in fest vorgegebenen Größen mit einer Länge von 1286 mm und einer Breite von 323 mm erhältlich. In seiner Länge ist es zur individuellen Anpassung der Plattenmaße an bauliche Gegebenheiten beliebig kürzbar.It is available in fixed sizes with a length of 1286 mm and a width of 323 mm. Its length can be shortened as required to individually adapt the panel dimensions to the structural conditions.
Die Verbindung zwischen den Solarmodulen 3 und den beiden Glasscheiben 1, 2 erfolgt jeweils über eine dazwischen liegende Folienlage 9, aus vier übereinanderliegenden Folien mittels der bei einem Verbundprozeß unter einer Temperatur von 150 bis 170° und einem Druck von etwa 15 bar eine Verklebung der beiden Scheiben 1, 2 mit dem Solarmodul 3 stattfindet. Bei den einzelnen Folien, die in Fig. 2 nicht einzeln herausgezeichnet sind, handelt es sich um Polyvinyl-butyral-Folie mit einer Dicke von jeweils 0,38 mm.The connection between the solar modules 3 and the two glass panes 1, 2 is made via an intermediate film layer 9, made of four superimposed films, by means of which the two panes 1, 2 are bonded to the solar module 3 in a bonding process at a temperature of 150 to 170° and a pressure of about 15 bar. The individual films, which are not shown individually in Fig. 2, are polyvinyl butyral films with a thickness of 0.38 mm each.
Wie insbesondere aus den Fig. 2 und 3 deutlich wird, stehen die beiden Glasscheiben 1, 2 mit ihren umlaufenden Randbereichen 10 über die außenseitigen Randkanten 11 der Solarmodule 3 hinaus, so daß zwischen diesen Randbereichen 10 eine allseitig umlaufende Randfuge 12 gebildet ist. Diese ist - bis auf einen schmalen außenseitigen Randbereich - durch eine Dichtungsmasse 13 verschlossen, die von dem Material der über die außenseitigen Randkanten 11 der Solarmodule 3 überstehenden und während des oben erwähnten Verbundprozesses erweichenden Folienlage 9 gebildet ist.As is particularly clear from Fig. 2 and 3, the two glass panes 1, 2 protrude with their peripheral edge regions 10 beyond the outer edge edges 11 of the solar modules 3, so that an all-round edge joint 12 is formed between these edge regions 10. This is closed - except for a narrow outer edge region - by a sealing compound 13, which is formed from the material of the film layer 9 that protrudes beyond the outer edge edges 11 of the solar modules 3 and softens during the above-mentioned bonding process.
Der elektrische Anschluß jeden Solarmoduls 3 erfolgt über zwei Anschlußkabel 14,14', deren abisolierten, modulseitigen Enden 15, 15' mit den Anschlußlötfahnen 8, 8' des jeweiligen Solarmoduls 3 verlötet sind. Wie aus Fig. 3 deutlich wird, sind die Anschlußlötfahnen 8,8' so umgelegt, daß sie in etwa paralleler Richtung zu der entsprechenden Querseite 7 des Solarmoduls 3 und aufeinander zuweisend verlaufen. In geradliniger Fortsetzung der Anschlußlötfahnen 8, 8' erstrecken sich die Anschlußkabel 14, 14', bis diese mittig bezogen auf die Breite B des Solarmoduls 3 aufThe electrical connection of each solar module 3 is made via two connecting cables 14, 14', the stripped, module-side ends 15, 15' of which are soldered to the connecting soldering lugs 8, 8' of the respective solar module 3. As is clear from Fig. 3, the connecting soldering lugs 8, 8' are folded over so that they run approximately parallel to the corresponding transverse side 7 of the solar module 3 and pointing towards each other. The connecting cables 14, 14' extend in a straight line continuation of the connecting soldering lugs 8, 8' until they are centered in relation to the width B of the solar module 3 on
einandertreffen und an dieser Position etwa rechtwinklig vom Solarmodul 3 weggeführt werden. Die Anschlußlötfahnen 8, 8' und die sich parallel zur Querseite 7 erstreckenden Abschnitte der Anschlußkabel 14, 14' sind vollständig in der Dichtungsmasse 13 eingebettet.meet each other and are led away from the solar module 3 at approximately a right angle at this position. The connection soldering lugs 8, 8' and the sections of the connection cables 14, 14' extending parallel to the transverse side 7 are completely embedded in the sealing compound 13.
Die über die außenseitigen Randkanten 11 der Solarmodule 3 überstehenden Randbereiche 10 der äußeren Glasscheibe 1 und deren mit den Stoßfugen zwischen den Solarmodulen 3 fluchtenden, streifenförmigen Bereiche sind mit einer Email-Beschichtung 16 versehen, deren Farbgebung und Oberflächenstruktur im wesentlichen der der photosensitiven Halbleiterbeschichtung der Solarmodule 3 entspricht. Die Beschichtung 16 kann in den Randbereichen 10 weggelassen werden, da diese Bereiche in der Regel im Einbauzustand der Fassadenplatte von den außenseitigen Gegenhalteleisten der Rahmen-Haltekonstruktion abgedeckt sind.The edge areas 10 of the outer glass pane 1 that protrude beyond the outer edge edges 11 of the solar modules 3 and their strip-shaped areas that are aligned with the butt joints between the solar modules 3 are provided with an enamel coating 16, the color and surface structure of which essentially corresponds to that of the photosensitive semiconductor coating of the solar modules 3. The coating 16 can be omitted in the edge areas 10, since these areas are usually covered by the outer counter-holding strips of the frame support structure when the facade panel is installed.
