Description
Solargeneratoren bestehen üblicherweise aus einzelnen Solarzellen, die zur Erreichung der erforderlichen Strom/Spannungsverhältnisse in Serie und, wenn erfor derlich, auch noch parallel verschaltet werden. Da für viele Anwendungen der zur Verfügung stehende Platz be schränkt ist, wird eine hohe Packungsdichte der Solar zellen sowie der erforderlichen Anschlüsse der Solar zellen zum Verschalten untereinander und zum Anschluß der Verbraucher gefordert. Dies wird bei bisher bekann ten Solargeneratoren teilweise dadurch gelöst, daß sehr aufwendige Anordnungen der Solarzellen gewählt werden, die zu relativ teuren Herstellverfahren führen, oder daß eine Randverschaltung einzelner Solarzellenstrings im Bereich des Solargeneratorrahmens erfolgt. Letztere Möglichkeit bietet sich jedoch nur dann, wenn ein ent sprechender Rahmen vorhanden und erforderlich ist. Es sind auch Anordnungen vorgeschlagen worden, bei denen die Anschlüsse durch einen Träger hindurch auf der Rückseite des Trägers im Bereich hinter den Solarzellen angebracht sind. Bei diesen Anordnungen sind jedoch ebenfalls Einschränkungen vorhanden, die eine wirt schaftliche Herstellung für eine universelle Anwendung nicht zulassen.Solar generators usually consist of individual ones Solar cells needed to achieve the necessary Current / voltage ratios in series and, if necessary deral, also be connected in parallel. Therefore many uses the available space is limited, a high packing density of the solar cells and the necessary connections of the solar cells for interconnection and for connection demanded by the consumer. This is known so far ten solar generators partially solved that very elaborate arrangements of the solar cells are selected, which lead to relatively expensive manufacturing processes, or that an edge connection of individual solar cell strings in the area of the solar generator frame. Latter However, this is only possible if an ent speaking framework is present and necessary. It Arrangements have also been proposed in which the connections through a carrier on the Back of the carrier in the area behind the solar cells are attached. However, with these arrangements there are also restrictions that one hosts economical production for universal application not allow.
Der Erfindung liegt die Aufgabe zugrunde einen Solar zellengenerator aus mehreren, mittels Verbindern mit einander verschalteten Solarzellen anzugeben, bei dem auch ohne einen Trägerkörper für die Solarzellen eine extrem platzsparende und technisch günstige Kontaktie rung des Generators oder seiner Teile möglich ist. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der durch den Vorderseitenkontakt einer Solarzelle ge bildete Endkontakt einer Zusammenschaltung an der Rück seite der gleichen Solarzelle zugänglich ist, in dem ein Teil der Rückseite mit einer Isolierschicht bedeckt ist, auf dieser Isolierschicht ein Metallkontakt ange ordnet ist und dieser Metallkontakt über Verbinder mit dem Vorderseitenkontakt elektrisch leitend verbunden ist.The invention has for its object a solar cell generator consisting of several, using connectors with indicate interconnected solar cells in which even without a support body for the solar cells extremely space-saving and technically favorable contact tion of the generator or its parts is possible. This object is achieved in that the ge through the front contact of a solar cell formed an interconnection end contact on the back side of the same solar cell is accessible in which part of the back is covered with an insulating layer is a metal contact on this insulating layer is assigned and this metal contact with connector the front side contact electrically connected is.
Wenn die Zusammenschaltung aus der Serienschaltung von Solarzellen innerhalb eines Strings besteht, so sind beide Anschlußkontakte an diesen String auf den Rück seiten der innerhalb des Strings an den Endpunkten lie genden Solarzellen angeordnet. Der Verbund aus mitein ander verschalteten Solarzellen kann folglich auf einem mit Anschlußkontakten versehenen Träger so angeordnet werden, daß keine zusätzlichen Flächen für Kontaktzwecke erforderlich sind. Ferner ist eine Durchkontaktierung durch Aussparungen im Träger im Bereich der Rückseiten anschlußkontakte möglich. Es können auch Solarzellen module gefertigt werden, bei denen nur die Solarzellen vorderseite mit einer Folie bedeckt ist, die dem Solar zellenverband Stabilität und Schutz verleiht, während die Rückseite und damit die dort befindlichen Anschluß kontakte an das Solarzellenmodul zugänglich sind. Solche Einheiten können in vielfältiger Weise für unterschied lichste Zwecke eingesetzt werden.If the interconnection from the series connection of There are solar cells within a string both connection contacts to this string on the back sides of the lie within the string at the end points arranged solar cells. The network of together other connected solar cells can consequently on one carrier provided with contacts arranged so be that no additional areas for contact purposes required are. There is also a via through cutouts in the carrier in the area of the backs connection contacts possible. It can also use solar cells modules are manufactured in which only the solar cells front is covered with a film that the solar zellenverband gives stability and protection while the back and thus the connection located there contacts to the solar cell module are accessible. Such Units can be differentiated in many ways most diverse purposes.
Die Erfindung und ihre vorteilhafte Ausgestaltung wird nachstehend noch anhand eines Ausführungsbeispieles näher erläutert. Die Figuren zeigen in Serie geschal tete Solarzellen, wobei die Fig. 1a die für den Licht einfall vorgesehene Vorderseite des Generators zeigt, während die Fig. 1b eine Draufsicht auf die Rückseite darstellt. In der Fig. 1c ist eine Schnittdarstellung wiedergegen.The invention and its advantageous embodiment will be explained in more detail below using an exemplary embodiment. The figures show solar cells connected in series, with FIG. 1a showing the front of the generator intended for the incident light, while FIG. 1b shows a top view of the rear. A sectional representation is shown in FIG. 1c.
Bei dem dargestellten Ausführungsbeispiel sind fünf Solarzellen 2, beispielsweise aus polykristallinem Silizium, in Serie geschaltet. Hierzu wird jeweils der Vorderseitenkontakt einer Zelle über Verbinder 6 a - 6 d mit dem Rückseitenkontakt der nachfolgenden Solarzelle elektrisch leitend verbunden. Die Rückseite der ersten Zelle innerhalb der Serienschaltung wird mit einem großflächigeren Anschlußkontakt 3 a versehen, der dann den positiven Pol des Generators bildet. Die Verbinder 6 und die großflächigeren Kontakte 3 a bzw. 3 b bestehen vorzugsweise aus Aluminium oder aus Aluminium/Silber. Die Anschlußkontakte 3 a und 3 b können auch aus Kupfer folien hergestellt werden. Der negative Anschluß an das dargestellte Solarzellenstring wird durch den Vorder seitenkontakt 6 e der letzten Zelle innerhalb der Reihen schaltung gebildet. Dieser Vorderseitenkontakt 6 e wird nun auf der Rückseite der gleichen Solarzelle zugäng lich gemacht. Dies geschieht dadurch, daß ein Teil dieser Rückseite mit einer Isolierschicht 4 abgedeckt wird, die beispielsweise aus temperaturbeständigem Klebeband, einer Klebefolie oder einem Glasfasergewebe besteht. Auf diese Isolierschicht wird ein metallischer Anschlußkontakt 3 b aufgebracht, der, wie bereits er wähnt, aus Aluminium, Aluminium/Silber oder Kupfer be steht. Dieser großflächige Anschlußkontakt 3 b wird über Verbinder 6 f mit dem Vorderseitenkontakt 6 e elektrisch leitend verbunden. Um Kurzschlüsse an der Seitenfläche der Solarzelle zu verhindern, wird die Isolierschicht 4 vorzugsweise über den seitlichen Rand der Solarzelle geführt so daß auch der Rand zumindest in den Berei chen, die für die Führung der Verbinder 6 f vorgesehen sind, elektrisch isoliert ist.In the illustrated embodiment, five solar cells 2 , for example made of polycrystalline silicon, are connected in series. For this purpose, the front side contact of a cell is electrically conductively connected to the rear side contact of the subsequent solar cell via connectors 6 a - 6 d . The back of the first cell within the series circuit is provided with a larger-area connection contact 3 a , which then forms the positive pole of the generator. The connector 6 and the larger-area contacts 3 a and 3 b are preferably made of aluminum or aluminum / silver. The contacts 3 a and 3 b can also be made of copper foils. The negative connection to the solar cell string shown is formed by the front side contact 6 e of the last cell within the series circuit. This front contact 6 e is now made accessible on the back of the same solar cell. This is done in that part of this back is covered with an insulating layer 4 , which consists for example of temperature-resistant adhesive tape, an adhesive film or a glass fiber fabric. On this insulating layer, a metallic connection contact 3 b is applied, which, as he already mentioned, is made of aluminum, aluminum / silver or copper. This large-area connection contact 3 b is electrically connected via connector 6 f to the front contact 6 e . In order to prevent short circuits on the side surface of the solar cell, the insulating layer 4 is preferably guided over the lateral edge of the solar cell so that the edge, at least in the areas provided for guiding the connector 6 f , is electrically insulated.
Das Laminat aus so verschalteten und mit Kontakten ver sehenen Solarzellen kann nun beispielsweise mit Hilfe einer Schmelzfolie 5 auf einer die Vorderseite der Solarzellen abdeckenden Folie 1 befestigt werden. Die Figuren zeigen Solarzellenmodule mit geschützten Vorder seiten der Solarzellen und frei zugänglichen Anschluß kontakten 3 a und 3 b auf der Rückseite der Anordnung, für die kein Platzbedarf außerhalb des Solarzellen verbandes erforderlich ist. Mehrere in den Figuren dargestellte Strings können nun gleichfalls ohne zu sätzlichen Platzbedarf dadurch parallel geschaltet werden, daß die Anschlußkontakte 3 a und 3 b der ver schiedenen Strings miteinander verschaltet werden. Schließlich kann die Gesamtanordnung auf einer geeig neten Unterlage befestigt werden. Der erfindungsgemäße Solarzellengenerator kann insbesondere dort eingesetzt werden, wo ein hohes Leistungsgewicht gefordert wird, wie beispielsweise bei Solarzellen-getriebenen Fahr zeugen oder Flugzeugen.The laminate of solar cells connected in this way and provided with contacts can now be fastened, for example with the aid of a melting film 5, to a film 1 covering the front side of the solar cells. The figures show solar cell modules with protected front sides of the solar cells and freely accessible connection contacts 3 a and 3 b on the back of the arrangement, for which no space is required outside the solar cell association. More strings shown in the figures can now also be switched to without sätzlichen space parallel characterized in that the connecting contacts 3 a and 3 b of the various strings are interconnected. Finally, the entire arrangement can be attached to a suitable pad. The solar cell generator according to the invention can be used in particular where a high power-to-weight ratio is required, such as for example in the case of solar cell-powered vehicles or aircraft.
