Description
Die Erfindung bezieht sich auf einen Solarzellenverbund mit mehreren Solarzellen nach dem Oberbegriff des Anspruches 1.The invention relates to a solar cell assembly with a plurality of solar cells according to the preamble of
Stand der TechnikState of the art
Ein derartiger Solarzellenverbund wird in der
Die rückseitige Fläche der Solarzellen ist mit einer Back-Surface-Field-Schicht versehen, bei der es sich um eine Diffusionsschicht vom p-Typ handelt, welche in einem thermischen Prozess aus einer aufgetragenen Aluminiumpaste erzeugt wird.The back surface of the solar cells is provided with a back surface field layer, which is a p-type diffusion layer, which is formed in a thermal process from an applied aluminum paste.
Offenbarung der ErfindungDisclosure of the invention
Der Erfindung liegt die Aufgabe zu Grunde, den Herstellungsprozess zum Erzeugen eines aus mehreren Solarzellen bestehenden Solarzellenverbundes zu vereinfachen.The invention is based on the object of simplifying the production process for producing a solar cell composite consisting of a plurality of solar cells.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.This object is achieved with the features of
Der Solarzellenverbund umfasst mehrere miteinander verbundene Solarzellen, von denen jeweils zwei benachbarte Solarzellen über eine Aluminiumfolie gekoppelt sind. Die Aluminiumfolie ist unmittelbar auf die Rückseite einer ersten Solarzelle des Solarzellenverbundes aufgebracht und dient zum Erzeugen einer Back-Surface-Field-(BSF)-Schicht. Die Aluminiumfolie ragt über die erste Solarzelle hinaus, wobei der hinausragende Abschnitt der Aluminiumfolie zu einer zweiten, benachbarten Solarzelle geführt und mit dieser verbunden ist.The solar cell assembly comprises a plurality of interconnected solar cells, of which two adjacent solar cells are coupled via an aluminum foil. The aluminum foil is applied directly to the back of a first solar cell of the solar cell assembly and serves to generate a back-surface field (BSF) layer. The aluminum foil projects beyond the first solar cell, wherein the protruding portion of the aluminum foil is guided to and connected to a second, adjacent solar cell.
Diese Ausführung weist verschiedene Vorteile auf. Zum einen muss im Unterschied zum Stand der Technik keine Aluminiumpaste aufgetragen werden, um eine Aluminiumquelle für die BSF-Schicht zu erhalten. Durch das Aufbringen der Aluminiumfolie auf die Rückseite der ersten Solarzelle entfällt ein sonst üblicher Siebdruckschritt.This embodiment has several advantages. First, unlike the prior art, no aluminum paste needs to be applied to obtain an aluminum source for the BSF layer. By applying the aluminum foil on the back of the first solar cell eliminates an otherwise usual screen printing step.
Da die Aluminiumfolie üblicherweise eine konstante Dicke aufweist, kann auch die BSF-Schicht mit hoher Genauigkeit und Gleichförmigkeit erzeugt werden.Since the aluminum foil usually has a constant thickness, the BSF layer can also be produced with high accuracy and uniformity.
Zusätzlich zum Ausbilden einer BSF-Schicht kommt der Aluminiumfolie eine Verbindungsfunktion der ersten Solarzelle mit der benachbarten, zweiten Solarzelle zu. Das Ausbilden einer BSF-Schicht und die Verbindung benachbarter Solarzellen erfolgt somit über ein gemeinsames Bauteil, nämlich die Aluminiumfolie. Zusätzliche Verbindungsmaßnahmen zwischen den Solarzellen sind nicht erforderlich. Die Aluminiumfolie dient außerdem als ein elektrischer Leiter zwischen den benachbarten Solarzellen.In addition to forming a BSF layer, the aluminum foil has a joining function of the first solar cell with the adjacent second solar cell. The formation of a BSF layer and the connection of adjacent solar cells thus takes place via a common component, namely the aluminum foil. Additional connection measures between the solar cells are not required. The aluminum foil also serves as an electrical conductor between the adjacent solar cells.
Die Verwendung einer Aluminiumfolie anstelle einer Kupferfolie, welche im Stand der Technik zur Verbindung benachbarter Solarzellen eingesetzt wird, hat darüber hinaus den Vorteil, dass eine Vergiftung der Solarzelle im Falle eines Prozessfehlers mit Kupfer vermieden wird.The use of an aluminum foil instead of a copper foil, which is used in the prior art for connecting adjacent solar cells, moreover has the advantage that a poisoning of the solar cell in the event of a process error with copper is avoided.
Gemäß einer vorteilhaften Ausführung ist die Aluminiumfolie formschlüssig mit der zweiten, benachbarten Solarzelle verbunden. Der Formschluss kann über eine mechanische Bearbeitung der Aluminiumfolie hergestellt werden, so dass darüber hinaus keine zusätzlichen Verbindungsmaßnehmen erforderlich sind. Beispielsweise kann in die Aluminiumfolie eine bzw. können mehrere Erhebungen eingeprägt sein, die sich in Richtung der zweiten Solarzelle erstrecken und dort in entsprechend geformte Ausnehmungen einragen. Diese Ausführung kann mit einem elektrischen Kontakt verbunden sein, dergestalt, dass die Erhebung in der Aluminiumfolie einen durch die zweite Solarzelle hindurch geführten Emitterkontakt berührt und zu diesem eine elektrische Verbindung herstellt.According to an advantageous embodiment, the aluminum foil is positively connected to the second, adjacent solar cell. The positive connection can be made by mechanical processing of the aluminum foil, so that no additional Verbindungsmaßnahmen are required beyond. For example, one or more elevations may be embossed in the aluminum foil, which extend in the direction of the second solar cell and protrude there into correspondingly shaped recesses. This embodiment may be connected to an electrical contact, such that the elevation in the aluminum foil contacts an emitter contact guided through the second solar cell and establishes an electrical connection to it.
Gemäß einer bevorzugten Ausführung weist der Solarzellenverbund mindestens zwei, vorteilhafterweise aber mehr als zwei Solarzellen auf, von denen jeweils zwei benachbarte Solarzellen über eine Aluminiumfolie miteinander verbunden sind. Dementsprechend existieren eine Mehrzahl einzelner Aluminiumfolien, die jeweils zwei benachbarte Solarzellen miteinander verbinden, wobei die Aluminiumfolie an jeweils einer Solarzelle zur Bildung der BSF-Schicht herangezogen wird. An der benachbarten Solarzelle liegt dagegen die Aluminiumfolie nicht unmittelbar auf und wird dort auch nicht zur Bildung der BSF-Schicht herangezogen; vielmehr befindet sich unmittelbar an der Rückseite dieser benachbarten Solarzelle eine weitere, separat ausgeführte Aluminiumfolie für die BSF-Schicht, wobei diese weitere Aluminiumfolie zu einer dritten Solarzelle geführt ist, um eine Verbindung mit dieser Solarzelle herzustellen.According to a preferred embodiment, the solar cell assembly has at least two, but advantageously more than two solar cells, of which in each case two adjacent solar cells are connected to one another via an aluminum foil. Accordingly, there are a plurality of individual aluminum foils, each of which connects two adjacent solar cells with each other, wherein the aluminum foil is used on each of a solar cell to form the BSF layer. On the other hand, the aluminum foil is not immediately adjacent to the adjacent solar cell and is not used there to form the BSF layer; rather, located directly on the back of this adjacent solar cell another, separately running aluminum foil for the BSF layer, said further aluminum foil is guided to a third solar cell to produce a connection with this solar cell.
Die mit zwei benachbarten Solarzellen verbundene, mittlere Solarzelle weist demzufolge auf ihrer Rückseite zwei parallele Aluminiumfolien auf, die jedoch über eine zwischenliegende Isolationsschicht elektrisch voneinander isoliert sind. Als Material der Isolationsschicht kommen beispielsweise Kunststoff, Keramik, Silikon oder sonstige Materialien in Betracht, die entweder als Folie oder Platte aufgetragen werden oder in flüssiger Form oder als Paste vorliegen und nach dem Auftragen aushärten. Die Isolationsschicht kann zugleich eine Verbindungsfunktion haben, beispielsweise durch Kleben an einer Aluminiumfolie oder an beiden Aluminiumfolien.The connected to two adjacent solar cells, medium solar cell therefore has on its back two parallel aluminum foils, the however, are electrically isolated from each other via an intermediate insulation layer. As the material of the insulating layer, for example, plastic, ceramic, silicone or other materials come into consideration, which are applied either as a film or plate or in liquid form or as a paste and harden after application. The insulating layer can at the same time have a connecting function, for example by gluing on an aluminum foil or on both aluminum foils.
Zweckmäßigerweise sind in die Aluminiumfolie, welche unmittelbar auf die Rückseite der Solarzelle aufliegt, Kontaktausnehmungen eingebracht, welche mit den Emitterkontakten in der Solarzelle korrespondieren. Dies ermöglicht es der darüber liegenden, zweiten Aluminiumfolie, welche von der benachbarten Solarzelle stammt, in elektrischen Kontakt mit dem Emitter zu treten. Hergestellt wird der elektrische Kontakt vorteilhafterweise, wie oben beschrieben, über Erhebungen, die in die Aluminiumfolien mechanisch eingeprägt sind und sich durch die Kontaktausnehmungen in der darunter liegenden Aluminiumfolie hindurch erstrecken.Expediently, contact recesses are introduced into the aluminum foil, which rests directly on the rear side of the solar cell, which correspond with the emitter contacts in the solar cell. This allows the overlying second aluminum foil, which originates from the adjacent solar cell, to make electrical contact with the emitter. The electrical contact is advantageously made, as described above, via protrusions which are mechanically impressed into the aluminum foils and extend through the contact recesses in the underlying aluminum foil.
Auch die Isolationsschicht zwischen den beiden parallel liegenden Aluminiumfolien weist vorteilhafterweise derartige Kontaktausnehmungen auf, die in der Ausführung der Isolationsschicht als Folie oder Platte zweckmäßigerweise direkt eingebracht sind oder in der Ausführung als ausgehärtete Flüssigkeit bzw. Paste während des Füge- bzw. Verbindungsprozesses entstehen.The insulating layer between the two parallel aluminum foils advantageously has such contact recesses, which are expediently incorporated directly in the embodiment of the insulating layer as a film or plate or arise in the execution as a cured liquid or paste during the joining or bonding process.
Bei einem Verfahren zum Herstellen eines Solarzellenverbunds, der eine Mehrzahl einzelner, miteinander verbundener Solarzellen aufweist, wobei je zwei benachbarte Solarzellen über eine Aluminiumfolie verbunden sind, welche an einer der Solarzellen zum Erzeugen einer BSF-Schicht genutzt wird, wird diese BSF-Schicht über ein thermisches Verfahren gebildet. Beispielsweise kann das Erzeugen der BSF-Schicht laserunterstützt durchgeführt werden.In a method for producing a solar cell assembly having a plurality of individual, interconnected solar cells, wherein each two adjacent solar cells are connected via an aluminum foil, which is used on one of the solar cells to produce a BSF layer, this BSF layer is on formed thermal process. By way of example, the generation of the BSF layer can be carried out with laser assistance.
