Mit Abdeckschichten versehener Solarzellenverband Solar cell assembly provided with covering layers
= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Die Erfindung bezieht sich auf einen mit Abdeckschichten versehenen Solarzellenverband, wie er bei Solargeneratoren Anwendung findet. = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = The invention relates to one with cover layers provided solar cell association, as it is used in solar generators.
Bekannte Solargeneratoren bestehen aus einem Verband aus Solarzellen auf Siliziumbasis, der zum Schutz zwischen Glasscheiben gelegt ist, die wiederum von einem Aluminiumrahmen umfaßt sind. Der Raum zwischen den Glasscheiben und den Solarzellen wird durch Kunststoff, z.B. auf Polyvinylbutyral-Basis ausgefüllt. Der Rahmen dient nicht nur zum mechanischen Schutz, sondern soll auch das Eindringen von Feuchtigkeit verhindern.Known solar generators consist of a group of solar cells based on silicon, which is placed between panes of glass for protection, which in turn are encompassed by an aluminum frame. The space between the panes of glass and the Solar cells are filled with plastic, e.g. based on polyvinyl butyral. Of the The frame is not only used for mechanical protection, but is also intended to prevent penetration prevent from moisture.
Man hat auch schon versucht, Abdeckschichten aus Kunststoff einzusetzen; jedoch tritt dabei als wesentliches Problem die unterschiedliche Wärmeausdehnung der Solarzellen und des Kunststoffsystems mit erheblich höherem Wärmeausdehnungs-Ko effizienten auf.Attempts have also been made to use plastic cover layers; however, the main problem here is the different thermal expansion the solar cells and the plastic system with a significantly higher thermal expansion coefficient efficient on.
Dadurch besteht die Gefahr, daß vom Rand des Solargenerators beginnend eine Delamination zwischen den Solarzellenoberflächen und dem Decklaminat auftritt.This creates the risk of starting from the edge of the solar generator delamination occurs between the solar cell surfaces and the cover laminate.
Versuchsweise verwendete Polyesterschichten vergilben und wurden trüb.Polyester layers used experimentally yellowed and became cloudy.
Strahlungsgehärtete Gießmassen auf Methacrylsäureester Basis, die mit Glasgewebe verstärkt wurden, haben sich ebenfalls als ungeeignet erwiesen, da ihre Haftung auf der verwendeten Zwischenschicht auf Polyvinylbutyral-Basis zu wünschen übrig ließ.Radiation-cured casting compounds based on methacrylic acid esters, the Reinforced with glass fabric have also proven unsuitable as to want their adhesion to the polyvinyl butyral-based intermediate layer used left.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, Abdeckschichten für den Solarzellenverband zu schaffen, wobei kein Wärmeausdehnungsproblem auftritt, so daß die Abdeckung und das Solarzellensystem annähernd einen gleichen Wärmeausdehnungs Koeffizienten aufweisen.The present invention is based on the object of covering layers for the solar cell assembly, with no thermal expansion problem occurring, so that the cover and the solar cell system have approximately the same thermal expansion Have coefficients.
Gelöst wird die Aufgabe erfindungsgemäß durch die im Kennzeichen des Anspruches 1 genannten Merkmale.The object is achieved according to the invention by the in the characterizing part of the Claim 1 mentioned features.
Durch Verwendung von Glasseidengeiegen läßt sich das Wärmeausdehnungsproblem beheben.By using fiberglass weights, the thermal expansion problem remedy.
Dabei hat es sich als vorteilhaft erwiesen, die Außenschicht in Längsrichtung der Zellenplatten zu legen, um eine Verbiegung unter dem Einfluß von Wärme zu vermeiden. Die gleiche Abdeckung kann auch auf der Rückseite der Solarzellenplatte vorgesehen werden, wobei diese evtl. dünner gehalten werden kann.It has been found to be advantageous to place the outer layer in the longitudinal direction of the cell plates to avoid bending under the influence of heat. The same cover can also be provided on the back of the solar cell panel , whereby this can possibly be kept thinner.
Die Abdeckung des Solarzellenverbandes erfolgt also durch ein System von Glasfaser und Bindemittel derart, daß Glasfasergelege verwendet werden, die in Längs- und Querrichtung angeordnet sind, wobei das Verhältnis Glasfaser zu Bindemittel so dimensioniert ist, daß der Wärmeausdehnungs-Koeffizient mit dem Solarzellenverband weitgehend übereinstimmt.The solar cell assembly is thus covered by a system of fiberglass and binder in such a way that fiberglass fabrics are used that are arranged in the longitudinal and transverse directions, the ratio of glass fiber to binder is dimensioned so that the coefficient of thermal expansion with the solar cell association largely coincides.
Als Bindemittel können an sich bekannte härtbare Harze verwendet werden, vorteilhaft können ungesättigte Polyester Anwendung finden, die eine verhältnismäßig große Widerstandsfähigkeit gegen Vergilben aufweisen.Known curable resins can be used as binders, unsaturated polyesters can advantageously be used, which are relatively have great resistance to yellowing.
Zur weiteren Anpassung des Sfärmeausdehnungskoeffizienten an den des Solarzellenverbandes können Füllstoffzusätze im Bindemittel eingesetzt werden, die die Transparenz nicht nachteilig beeinflussen; z.B. hat sich ein Füllstoff auf Glasmehlbasis als geeignet erwiesen.To further adapt the thermal expansion coefficient to that of the Solar cell association, filler additives can be used in the binder do not adversely affect transparency; E.g. a filler based on glass powder has proven itself proved suitable.
Die Erfindung wird im folgenden anhand der Abbildung an einem Ausführungsbeispiel erläutert: Fig. 1 zeigt schematisch eine Draufsicht auf einen Solarzellenverband, Fig. 2 zeigt im Querschnitt einen Aufbau des mit einer Abdeckung aus glasfaserverstärktem Harz versehenen Solarzellenverbandes, Fig. 3 zeigt einen Querschnitt der Glasfaserverstärkung im Ausschnitt.The invention is illustrated below using an exemplary embodiment explained: Fig. 1 shows a schematic plan view of a solar cell array, Fig. 2 shows in cross section a structure of the with a cover made of glass fiber reinforced Resin-coated solar cell assembly, Fig. 3 shows a cross section of the glass fiber reinforcement in the cutout.
Der in Fig. 1 schematisch dargestellte Solarzellenverband 1 ist von einem Rahmen 2 umgeben.The solar cell array 1 shown schematically in FIG. 1 is from surrounded by a frame 2.
Fig. 2 zeigt Solarzellen 21, die von einem Glasfasergelege mit Glasfasern in Querrichtung 22 und Glasfasern in Längsrichtung 23 überdeckt sind.Fig. 2 shows solar cells 21, which are made of a glass fiber fabric with glass fibers are covered in the transverse direction 22 and glass fibers in the longitudinal direction 23.
Über diesem Glasfasergelege ist eine Polyvinylfluorid-Folie 24 aufgebracht, die mit einer Metallisierungsschicht 25 überdeckt ist, deren Schichtdicke 1/4 der Lichtwellenlänge beträgt.A polyvinyl fluoride film 24 is applied over this glass fiber fabric, which is covered with a metallization layer 25, the layer thickness of which is 1/4 of Light wavelength is.
Auf der Unterseite der Solarzelien 21 befindet sich ebenfalls ein Glasfasergelege aus in Querrichtung verlaufenden Glasfasern 26 und in Längsrichtung verlaufenden Glasfasern 27.On the underside of the solar panels 21 there is also a Glass fiber fabric made of glass fibers 26 running in the transverse direction and in the longitudinal direction running glass fibers 27.
Fig. 3 stellt einen vergrößerten Querschnitt der Glasfasergelegeschicht dar. Sie weist eine in Längsrichtung verlaufende Faserschicht 21 auf mit einer darunter in Querrichtung ved aufenden-Glasfaser#hicht 22. Beide Schichten sind mit Glasfasermatten 23 und 24 abgedeckt.3 shows an enlarged cross-section of the fiberglass scrim layer It has a longitudinal fiber layer 21 with one underneath in the transverse direction ved end-glass fiber # hicht 22. Both layers are with glass fiber mats 23 and 24 covered.
