Die Erfindung betrifft ein Verfahren zur Herstellung einer Sonnenbatterie, bei dem parallel und hintereinander angeordnete Sonnenzellen auf einer Isolierstoffplatte angebracht und durch Verlöten miteinander verbunden werden.The invention relates to a method for producing a solar battery in which parallel and one behind the other arranged solar cells attached to an insulating plate and soldered together get connected.
Bei bekannten Verfahren der erwähnten Art werden die einzelnen Zellen, nachdem sie vorher mittels eines Klebers auf einer Isolierstoffplatte festgekittet wurden, miteinander verlötet, indem S-förmige Verbindungsdrähte mittels eines Lötkolbens von Hand ίο angelötet werden. Der Nachteil eines derartigen Verfahrens besteht darin, daß beim von Hand erfolgenden Verlöten mittels Lötkolben die einzelnen Zellen einer lokalen Erwärmung unterworfen werden, welche zu einer Beschädigung bzw. Zerstörung der einzelnen Zellen führen kann. Zumindestens läßt sich das Entstehen von Spannungen in den Zellen sowie gegenüber benachbarten Zellen und der Isolierstoffplatte nicht vermeiden.In known methods of the type mentioned, the individual cells, after previously using an adhesive cemented onto a sheet of insulating material, soldered together using S-shaped connecting wires be soldered by hand using a soldering iron ίο. The disadvantage of such a procedure consists in the fact that when soldering by hand with a soldering iron, the individual cells be subjected to local heating, which leads to damage or destruction of the individual Cells can lead. At least the emergence of tensions in the cells as well as opposite Do not avoid neighboring cells and the insulating plate.
Zweck der Erfindung ist die Schaffung eines Verfahrens, bei welchem die Zellen nicht nur ohne Gefahr auf eine Grundplatte aufzubringen und dort zu verlöten sind, sondern später auch im Betrieb extreme Temperaturschwankungen aushalten, ohne daß infolge unterschiedlicher thermischer Ausdehnung Spannungen und Brüche entstehen. Erreicht wird dies nach der Erfindung dadurch, daß die Isolierstoffplatte mit aus lötfähigem Material bestehenden Streifen versehen wird, auf welche Lotschichten tragende Sonnenzellen aufgelegt werden, und daß in einem Ofen bei der Schmelztemperatur der Lotschichten jeweils die eine Lotschicht der Sonnenzellen mit den Streifen und jeweils die andere Lotschicht durch die Lötfahnen mit je einem der benachbarten Streifen verlötet werden.The purpose of the invention is to create a method in which the cells are not only without danger to be applied to a base plate and soldered there, but later also extreme during operation Withstand temperature fluctuations without this as a result of different thermal expansion Tensions and breaks arise. This is achieved according to the invention in that the insulating plate provided with strips made of solderable material will be placed on which solder layers carrying solar cells, and that in an oven at the Melting temperature of the solder layers in each case the one solder layer of the solar cells with the strips and each the other layer of solder can be soldered to one of the adjacent strips through the soldering lugs.
Die Erfindung ist nachstehend an Hand der Zeichnung näher erläutert. Es zeigtThe invention is explained in more detail below with reference to the drawing. It shows

Jede auf der Isolierstoffplatte anzubringende Sonnenzelle 22 weist an ihrer Oberseite eine mit einer Zinnlotschicht 34 überzogene Nickelschicht 33 und an ihrer Unterseite eine mit einer Zinnlotschicht 37 überzogene Nickelschicht 36 auf. Ferner ist in einem Randbereich jeder Sonnenzelle 22 an deren Oberseite eine streifenförmige Zinnlotschicht 24 angebracht. Each solar cell 22 to be attached to the insulating material plate has a nickel layer 33 coated with a tin solder layer 34 on its upper side and a nickel layer 36 coated with a tin solder layer 37 on its lower side. Furthermore, a strip-shaped tin solder layer 24 is applied in an edge region of each solar cell 22 on the upper side thereof.
Eine Gruppe von Sonnenzellen 22 der erwähnten Art wird auf der Isolierstoffplatte 19 nach Art einer Matrix mit Zeilen und Spalten angeordnet, wobei in einer gleichen Zeile befindliche Sonnenzellen 22 durch die Streifen 21 parallel geschaltet sind. Über den Lotschichten jeweils einer Matrixzeile entsprechender Sonnenzellen 22 wird eine Lötfahne 23 angebracht, welche zwischen benachbarten Sonnenzellen mit ausdehnungsfähigen Längsabschnitten 12 in Form von Ausbauchungen versehen ist. Jede Lötfahne 23 ist an ihren Enden mit einem abgewinkelten Schenkelabschnitt 23 a versehen, welcher sich von einer Matrixzeile von Sonnenzellen 22 zu einer benachbarten Matrixzeile erstreckt und dort mit einem entsprechenden Schenkelabschnitt 13 eines zu dieser benachbarten Matrixzeile gehörigen Streifens 21 verlötbar ist, um eine Serienschaltung der einzelnen Matrixzeilen zu bewirken. Die Lötfahnen 23 erstrecken sich somit genau wie die Streifen 21 jeweils über die Länge einer Zeile von parallel geschalteten Sonnenzellen 22. A group of solar cells 22 of the type mentioned is arranged on the insulating material plate 19 in the manner of a matrix with rows and columns, with solar cells 22 located in the same row being connected in parallel by the strips 21. A soldering lug 23, which is provided with expandable longitudinal sections 12 in the form of bulges between adjacent solar cells, is attached over the solder layers of a respective matrix line of solar cells 22. Each soldering lug 23 is provided at its ends with an angled leg section 23 a, which extends from a matrix line of solar cells 22 to an adjacent matrix line and can be soldered there to a corresponding leg section 13 of a strip 21 belonging to this adjacent matrix line in order to create a series connection of the to effect individual matrix lines. The soldering lugs 23 thus extend exactly like the strips 21 in each case over the length of a row of solar cells 22 connected in parallel.
Nachdem die Sonnenzellen 22 nebst den zugehörigen Lötfahnen 23 in der beschriebenen Weise auf der Isolierstoffplatte 19 angeordnet wurden, ergibt sichAfter the solar cells 22 together with the associated soldering lugs 23 have been arranged on the insulating material plate 19 in the manner described, this results

eine Schnittdarstellung gemäß F i g. 2. Die auf diese Weise hergestellte Sonnenzellenanordnung wird in eine (nicht gezeigte) feuerfeste Vorrichtung eingespannt und als Gesamtheit in einen Ofen eingebracht, welcher eine der Schmelztemperatur der Lotschichten 24, 37 entsprechende Temperatur erreichen kann. In diesem Ofen wird gemäß F i g. 3 bei der Schmelztemperatur der Lotschichten jeweils die eine Lotschicht 37 jeder Sonnenzelle mit dem zugehörigen Streifen 21 (bzw. dessen Lotschicht 21 α) und jeweils die andere Lotschicht 24 durch die zugehörige Lötfahne 23 mit je einem der benachbarten Streifen 21 verlötet.a sectional view according to FIG. 2. The solar cell arrangement produced in this way is shown in a refractory device (not shown) clamped and placed as a whole in a furnace, which can reach a temperature corresponding to the melting temperature of the solder layers 24, 37. In this oven, according to FIG. 3 each one solder layer at the melting temperature of the solder layers 37 of each solar cell with the associated strip 21 (or its solder layer 21 α) and in each case the other solder layer 24 through the associated solder lug 23 with one of the adjacent strips 21 each soldered.
Durch die genaue Einstellung der in dem Ofen herrschenden Temperatur wird eine gleichmäßige Erwärmung der gesamten Sonnenbatterie während des Lötvorgangs erzielt, so daß örtliche Erhitzungen, welche zu Spannungen oder nachfolgendem Bruch führen können, zuverlässig vermieden werden.The exact setting of the temperature prevailing in the furnace ensures uniform heating of the entire solar battery achieved during the soldering process, so that local heating, which can lead to tension or subsequent breakage, can be reliably avoided.
