SolargeneratorSolar generator
Die Erfindung betrifft einen Solargenerator mit einer Vielzahl von in Reihe und/oder parallelgeschalteten Solarzellen, bei dem jeweils benachbarte Solarzellen durch metallische Verbinder elektrisch und mechanisch miteinander verbunden sind.The invention relates to a solar generator with a large number of solar cells connected in series and / or in parallel, in which adjacent solar cells are electrically and mechanically connected to one another by metallic connectors.
Ein derartiger Solargenerator ist beispielsweise in "ESA SP-140", (November 1978), Seiten 33 bis 40, beschrieben. Für die Herstellung photovoltaischer Solargeneratoren wird eine Vielzahl von Solarzellen elektrisch leitend miteinander verbunden. Eine Kette von in Serie geschalteten Solarzellen entsteht dadurch, daß die mehr oder weniger starren Zellen aus Silicium mittels duktiler Verbinder in Folge hintereinander angeordnet sind. Als Verbinder wurden bisher metallische Bänder mit einer Dicke von etwa 30 μm aus Silber oder aus silberbeschichtetem Molybdän verwendet, die mit der Zellenmetallisierung durch Widerstandsschweißen oder durch Löten verbunden werden.Such a solar generator is described for example in "ESA SP-140" (November 1978), pages 33 to 40. A large number of solar cells are connected in an electrically conductive manner for the production of photovoltaic solar generators. A chain of solar cells connected in series results from the fact that the more or less rigid cells made of silicon are arranged one behind the other by means of ductile connectors. So far, metallic tapes with a thickness of approximately 30 μm made of silver or silver-coated molybdenum have been used as connectors, which are connected to the cell metallization by resistance welding or by soldering.
Diese in Reihe elektrisch und mechanisch miteinander verbundenen Solarzellen werden mit Hilfe eines elastischen Siliconklebers auf eine starre oder flexible Unterlage aufgeklebt. Durch Parallelschaltung mehrerer derartigerThese solar cells, which are electrically and mechanically connected to each other in series, are glued to a rigid or flexible base with the help of an elastic silicone adhesive. By connecting several such in parallel
Solarzellenketten entsteht dann ein sogenannter Solarzellenmodul.A so-called solar cell module is then created.
Schwierigkeiten ergeben sich nun dadurch, daß die Ausdehnungskoeffizienten der Solarzellen, des Verbinderwerkstoffs und des Substratmaterials unterschiedlich
sind, und zwar derart, daß in der Regel der Ausdehnungskoeffizient des Substrats (etwa 20 x 10"6 IC-1 ) größer als der Ausdehnungskoeffizient des Verbinders ( für Ag 19 x 10"6 K~ l ) ist und dieser wiederum größer als der Ausdehnungskoeffizient der Solarzelle (ca. 2,5 x 10-6 K"x ) . Insbesondere bei der Anwendung derartiger Solargeneratoren zur Stromversorgung von Satelliten müssen die Generatoren eine Vielzahl thermischer Zyklen durchlaufen, und zwar mit Temperaturänderungen bis zu 250 °K. Die dabei auftretenden thermischen Dehnungsdifferenzen soll der Solarzellenverbinder als flexibles, bis in den plastischen Bereich verformbares Material möglichst bis zu einer Lebensdauer von 50 000 oder sogar 100 000 Zyklen akkommodieren.Difficulties now arise from the fact that the expansion coefficients of the solar cells, the connector material and the substrate material differ are such that the expansion coefficient of the substrate (about 20 x 10 " 6 IC -1 ) is usually greater than the expansion coefficient of the connector (for Ag 19 x 10" 6 K ~ l ) and this in turn is greater than that Expansion coefficient of the solar cell (approx. 2.5 x 10 -6 K " x ). Especially when using such solar generators for the power supply of satellites, the generators have to go through a large number of thermal cycles, with temperature changes of up to 250 ° K Thermal expansion differences should be accommodated by the solar cell connector as a flexible material that can be deformed into the plastic area, if possible up to a service life of 50,000 or even 100,000 cycles.
Bei einem Abstand der Solarzellen von ca. 1 mm ist der Solarzellenverbinder von der Zellenrückseite der einen Zelle zur Zellenvorderseite der nächsten geführt und muß somit die gesamte Dehnungsdifferenz (typisch ca. 0,05 mm) einer geradlinigen Verbindungslinie aufnehmen. Zur Schonung des Materials wird dem Zellenverbinder zwischen den beiden Solarzellen eine U-förmige Überhöhung gegeben, die als Ausgleichsbogen eine sogenannte geometrische Dehnung bewirkt und damit eine gewisse Entlastung des Verbinders ermöglicht. Da der Verbinder, wie bereits erwähnt, ständigen Dehn- Wechselbeanspruchungen unterliegt, treten imAt a distance of approx. 1 mm between the solar cells, the solar cell connector is guided from the back of one cell to the front of the next cell and must therefore accommodate the entire difference in elongation (typically approx. 0.05 mm) of a straight connecting line. In order to protect the material, the cell connector between the two solar cells is given a U-shaped elevation, which causes a so-called geometric expansion as a compensation arch, thus allowing the connector to be relieved to a certain extent. Since, as already mentioned, the connector is subject to constant expansion and alternating stresses,
Verbinderwerkstof Gefügeveränderungen auf, die als zyklische Verfestigungen nach einer bestimmten Anzahl von Lastspielen zum Anriß und schließlich zum Bruch des Verbinders führen.Changes in the structure of the connector material which, as cyclical hardening, lead to the cracking and finally to the breakage of the connector after a certain number of load cycles.
Die Kontaktierungsstelle des Verbinders mit der Zellenmetallisierung ist durch die Auswirkung der Dehnungsunterschiede infolge thermischer Zyklen besonders stark beansprucht, was sich in dort auftretenden Scherbrüchen äußert. Alle bisher eingesetzten Werkstoffkombinationen Substrat/Zelle/Verbinder führten spätestens nach Durchlaufen von 15 000 bis 30 000 thermischen Zyklen zu Schädigungen in
Form von zunächst Anrissen und später Brüchen der Schweißstellen oder der Verbinder.The contact point of the connector with the cell metallization is particularly stressed by the effect of the expansion differences due to thermal cycles, which is reflected in the shear fractures that occur there. All previously used substrate / cell / connector material combinations caused damage at the latest after going through 15,000 to 30,000 thermal cycles Form of cracks at first and later breaks of the welds or the connectors.
Der Erfindung liegt die Aufgabe zugrunde, einen Verbinder für einen Solargenerator verfügbar zu machen, der eine noch höhere Anzahl thermischer Zyklen durchlaufen kann, ohne daß ein Bruch oder ein Anriß des Materials auftritt und insbesondere auch eine dynamische Verfestigung desselben vermieden wird.The invention has for its object to provide a connector for a solar generator, which can undergo an even higher number of thermal cycles without breaking or cracking of the material and in particular also avoiding dynamic consolidation of the same.
Diese Aufgabe wird bei einem Solargenerator der eingangs definierten Art dadurch erzielt, daß der Verbinder aus einem pseudoelastischen Werkstoff besteht.This object is achieved in a solar generator of the type defined in the introduction in that the connector consists of a pseudo-elastic material.
Bei Verwendung eines derartigen Verbinders in einem photovoltaischen Solargenerator lassen sich im orbitalen Einsatz eines Satelliten thermische Zyklen von 50 000 bis 100 000 realisieren, ohne daß Defekte in der mechanischen oder elektrischen Verbindung der miteinander verbundenen Zellen auftreten.If such a connector is used in a photovoltaic solar generator, thermal cycles of 50,000 to 100,000 can be realized in the orbital use of a satellite without defects in the mechanical or electrical connection of the interconnected cells.
Bei der Gruppe der pseudoelastischen Werkstoffe handelt es sich um Werkstoffe, die reversible Verformungen ertragen können, die weit über die elastische Grenze (Ende der Hooke' sehen Gerade) des Werkstoffs hinausgehen. Hierzu wird beispielsweise auf "Metall 39", 1985, Seiten 34 bis 38, verwiesen. Diese Werkstoffe werden auch als Formgedächtnis- Legierungen bezeichnet. Sie zeigen aufgrund einer thermoelastischen martensitischen Umwandlung nach geeigneter Behandlung eine temperaturabhängige Gestaltsänderung. Wird z. B. eine derartige Legierung bei tiefer Temperatur bleibend verformt, so erinnert sie sich bei Erwärmung über eine kritische Temperatur an ihre ursprüngliche Form und nimmt diese wieder an. Bei einem pseudoelastischen Werkstoff tritt bei Erreichen einer bestimmten Beanspruchungsspannung eine martensitische Gefügeumwandlung statt, die eine weitere Verformung zuläßt, die nicht auf einer versetzungsbedingten elastischen Verformung beruht. Wird nach einer derartigen Verformung die mechanische Spannung weggenommen, so tritt eine
Rückdehnung bis zur ursprünglichen Gestalt ein, wobei der ursprüngliche Gefügezustand erhalten bleibt.The group of pseudo-elastic materials are materials that can withstand reversible deformations that go far beyond the elastic limit (end of the Hooke 'see straight line) of the material. For this, reference is made, for example, to "Metall 39", 1985, pages 34 to 38. These materials are also known as shape memory alloys. Due to a thermoelastic martensitic transformation, they show a temperature-dependent change in shape after suitable treatment. Is z. B. such an alloy permanently deformed at low temperature, it remembers when heated to a critical temperature to its original shape and takes it back. In the case of a pseudoelastic material, a martensitic structural transformation takes place when a certain stress is reached, which permits further deformation that is not based on an elastic deformation caused by displacement. If the mechanical tension is removed after such a deformation, one occurs Stretching back to the original shape, while maintaining the original structural state.
Bei Einsatz eines pseudoelastischen Werkstoffes als Verbinder für einen Solargenerator lassen sich Werkstoffdehnungen von bis zu 8 % pseudoelastisch akkom odieren. Die Anzahl der durchf hrbaren thermischen Zyklen läßt sich noch dadurch erhöhen, daß dem Verbinder eine geeignete Geometrie gegeben wird, beispielsweise in Form einer U-förmigen Überhöhung in dem Bereich zwischen den beiden Solarzellen, die von dem Verbinder miteinander verbunden werden.When using a pseudo-elastic material as a connector for a solar generator, material expansions of up to 8% can be accommodated pseudo-elastically. The number of thermal cycles that can be carried out can be increased further by giving the connector a suitable geometry, for example in the form of a U-shaped elevation in the area between the two solar cells which are connected to one another by the connector.
