Description
Die Erfindung betrifft einen vorzugsweise lichtdurchlässigen Scheibenaufbau für Fahr zeuge, insbesondere einen lichtdurchlässigen Deckel für Schiebedächer, Hebedächer und dergleichen mit einer oben liegenden transparenten Scheibe, einem an der Innenseite der Scheibe flächig anliegenden amorphen Halbleiterwerkstoff und einer sich an den Halbleiterwerkstoff nach unten anschließenden Abdeckung. Die Erfindung betrifft ferner eine Vorrichtung und ein Verfahren zum Herstellen eines derartigen Scheibenaufbaues.The invention relates to a preferably translucent pane structure for driving witness, in particular a translucent cover for sunroofs, sunroofs and the like with an overhead transparent disc, one on the Inside of the pane flat amorphous semiconductor material and one cover connected to the semiconductor material at the bottom. The invention relates furthermore an apparatus and a method for producing such a device Pane construction.
Bei einem aus der DE-C2-37 13 854 bekannten lichtdurchlässigen Scheibenaufbau ist die obere Scheibe zur Erzeugung von Solarzellen an ihrer Unterseite mit amorphem Silizium derart beschichtet, daß die Randbereiche undurchsichtig und der Zentralbereich aufgrund einer Gitterstruktur lichtdurchlässig ist. An die amorphe Siliziumschicht schließt sich bei einer Ausführungsform nach unten als Abdeckung eine zweite Scheibe an. In einem derartigen Verbund aus zwei Scheiben liegen die Solarzellen zwar optimal geschützt, ein solcher Scheibenaufbau weist jedoch auch erhebliche Nachteile auf. So sind Verbundglasscheiben einer Scheibe aus Einscheibensicherheitsglas (im folgenden als ESG abgekürzt) hinsichtlich ihrer Stabilität deutlich unterlegen. Dieser Nachteil könnte durch eine größere Dicke der Einzelscheiben oder eine stabilere Unterkonstruktion (Deckelinnenblech) in den Randbereichen zwar ausgeglichen werden; dies würde sich jedoch nachteilig in einer Vergrößerung der Bauhöhe auswirken. In a translucent pane structure known from DE-C2-37 13 854 the upper pane for the production of solar cells on its underside with amorphous Silicon coated so that the edge areas are opaque and the central area is translucent due to a lattice structure. Connects to the amorphous silicon layer In one embodiment, a second pane is attached as a cover. In Such a composite of two panes, the solar cells are optimal protected, such a pane structure also has considerable disadvantages. So are laminated glass panes of a pane made of toughened safety glass (in the following abbreviated as ESG) in terms of stability. This disadvantage could be due to a greater thickness of the individual panes or a more stable one Substructure (inner cover sheet) balanced in the edge areas become; however, this would be disadvantageous in increasing the overall height impact.
Bei einem weiteren, im Solardeckel des Fahrzeuges vom Typ MAZDA SENTIA verwendeten Scheibenaufbau wird unter eine obere Scheibe aus ESG ein mit a-Silizium beschichtetes Trägermaterial, wie beispielsweise Glas, mit einer transparenten Klebefolie, wie etwa Ethylen-Vinylacetat-Copolymer (EVA) und einer darunter liegenden transparenten Abdeckung zusammenlaminiert. Als Abdeckung dient Glas oder eine transparente Folie. Unterlaminiertes Trägermaterial unter eine formgebende Scheibe kann aber aus Festigkeitsgründen nur im Durchsichtsbereich der Scheibe liegen. Der Randbereich kann daher nicht mit Halbleiterwerkstoff bedeckt werden. Somit steht den Solarzellen nur der Zentralbereich der Scheibe zur Verfügung, wodurch sich die Ausbeute an Solarenergie insgesamt vermindert.Another, in the solar cover of the MAZDA SENTIA vehicle The pane structure used is placed under an upper pane made of toughened safety glass with a-silicon coated carrier material, such as glass, with a transparent Adhesive film, such as ethylene vinyl acetate copolymer (EVA) and an underlying one transparent cover laminated together. Glass or a serves as cover transparent film. Underlaminated carrier material under a shaping disc However, for reasons of strength, it can only be in the see-through area of the pane. Of the The edge area can therefore not be covered with semiconductor material. Thus stands the Only the central area of the pane is available for solar cells, which makes the Total yield of solar energy reduced.
Die Aufgabe der Erfindung besteht darin, einen vorzugsweise lichtdurchlässigen Scheibenaufbau zur Verwendung in Fahrzeugen der eingangs genannten Art zu schaffen, der hohe Stabilität bei geringer Bauhöhe und einer genannten Energieausbeute ermöglicht. Ferner soll eine zur Herstellung eines derartigen Scheibenaufbaus geeignete Vorrichtung sowie ein entsprechendes Verfahren geschaffen werden.The object of the invention is a preferably translucent Disc structure for use in vehicles of the type mentioned create the high stability with a low overall height and a specified energy yield enables. Furthermore, one should be suitable for producing such a pane structure Device and a corresponding method are created.
Gelöst wird die Aufgabe mit den Merkmalen des kennzeichnenden Teils der Patentansprüche 1, 13 bzw. 16.The task is solved with the characteristics of the characteristic part of the Claims 1, 13 and 16 respectively.
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous developments of the invention are the subject of the dependent claims.
Vorteilhaft an der Erfindung ist, daß leichtere Scheiben als bisher üblich hergestellt werden können. Sie sind auch preisgünstiger, da nur im Durchsichtsbereich (Zentralbereich), in dem eine transparente Folie, Scheibe oder Lack das amorphe Silizium abdeckt, eine Verbundbildung erfolgt. Die erfindungsgemäße Scheibe hat etwa die gleiche Stabilität und Festigkeit wie eine Einscheibensicherheitsglasscheibe ohne Siliziumschicht.The advantage of the invention is that lighter panes are manufactured than has been customary up to now can be. They are also cheaper because they are only in the viewing area (Central area), in which a transparent film, disc or lacquer the amorphous Silicon covers, a bond is formed. The disc according to the invention has approximately the same stability and strength as a single-pane safety glass pane without Silicon layer.
In der erfindungsgemäßen Vorrichtung kann ohne jede Werkzeugänderung sowohl eine Glasscheibe ohne Siliziumschicht als auch eine erfindungsgemäße Scheibe umschäumt werden.In the device according to the invention, both a Glass pane without a silicon layer and a pane according to the invention is foamed become.
Im folgenden wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels unter Bezugnahme auf die Zeichnungen erläutert. Es zeigen In the following, the invention is described using a preferred exemplary embodiment Explained with reference to the drawings. Show it
Fig. 1 einen Teilschnitt durch einen lichtdurchlässigen Scheibenaufbau in Einbaulage und Fig. 1 shows a partial section through a translucent pane structure in the installed position and
Fig. 2 einen Teilschnitt durch einen Scheibenaufbau nach Fig. 1 in Schäumlage in der Vorrichtung. Fig. 2 shows a partial section through a pane structure according to Fig. 1 in the foam position in the device.
Der in Fig. 1 veranschaulichte lichtdurchlässige Scheibenaufbau 10, der insbesondere ein lichtdurchlässiger Deckel für ein Fahrzeug-Schiebedach, -Hebedach oder dergleichen sein kann, weist eine durchsichtige obenliegende Einscheibensicherheitsglasscheibe 11 auf, die auf der in Einbaulage zum Fahrzeuginneren zeigenden Seite ganzflächig mit amorphem Silizium 12 beschichtet ist. Die Scheibe 11 ist vorzugsweise gewölbt und thermisch oder chemisch vorgespannt. Im Außenbereich 13 der Scheibe 11, der auch als Befestigungsbereich bezeichnet werden kann, ist die amorphe Siliziumschicht 12 undurchsichtig und im Innenbereich 14 vorzugsweise durchsichtig. Bei metallischem Rückkontakt wird die Schicht 12 im Innenbereich 14 durch transparente Unterbrechungen durchsichtig gestaltet. Der durchsichtige Innenbereich 14 der Siliziumschicht ist von einer transparenten Klebefolie 15 aus beispielsweise Ethylen-Vinylacetat-Copolymer (EVA) oder Polyvinylbutyral (PVB) bedeckt. Unterhalb derselben (bezogen auf Fig. 1) ist eine transparente Abdeckung 16 aus Polyethylenterephthalat- (PETP) Folie oder aus Glas angeordnet ist. Als Alternative zu Folien 15, 16 oder Glas kann die durchsichtige Fläche an der mit amorphem Silizium beschichteten Seite mit einem transparenten, kratzfesten Schutzlack geschützt werden. Hierzu eignen sich z. B. GE- Lacke oder Ormocere, wie sie z. B. zur kratzfesten Beschichtung von Kunststoffen verwendet werden. Diese Lacke können aufgespritzt oder aufgeschleudert werden. Bei Verwendung von Lack als Abdeckung 16 kann sich dieser auch über die Außenbereiche 13 der Scheibe 13 erstrecken, da die Lackschicht sehr dünn ist und die Bauhöhe des Scheibenaufbaus nur unwesentlich vergrößert.The translucent pane structure 10 illustrated in FIG. 1, which can be, in particular, a translucent cover for a vehicle sunroof, sunroof or the like, has a transparent, single-pane safety glass pane 11 on the whole, with amorphous silicon 12 on the side pointing towards the vehicle interior in the installed position is coated. The disc 11 is preferably curved and thermally or chemically biased. In the outer region 13 of the pane 11 , which can also be referred to as the fastening region, the amorphous silicon layer 12 is opaque and in the inner region 14 it is preferably transparent. In the case of metallic back contact, the layer 12 in the inner region 14 is made transparent by transparent interruptions. The transparent inner region 14 of the silicon layer is covered by a transparent adhesive film 15 made of, for example, ethylene-vinyl acetate copolymer (EVA) or polyvinyl butyral (PVB). A transparent cover 16 made of polyethylene terephthalate (PETP) film or of glass is arranged underneath the same (based on FIG. 1). As an alternative to foils 15 , 16 or glass, the transparent surface on the side coated with amorphous silicon can be protected with a transparent, scratch-resistant protective lacquer. For this purpose, z. B. GE varnishes or Ormocere, as z. B. for scratch-resistant coating of plastics. These paints can be sprayed on or spun on. When using lacquer as a cover 16, it can also extend over the outer regions 13 of the pane 13 , since the lacquer layer is very thin and the structural height of the pane structure increases only insignificantly.
Die Einscheibensicherheitsglasscheibe 11 ist im Außenbereich 13 in Form eines Einfaßrahmens 17 mit Polyurethan oder einer Mischung aus Polyurethanen umschäumt. Im Schaum liegt auf der beschichteten Seite der Glasscheibe 11 durch eine vom Einfaßrahmen 17 ausgehende Kunststoff-Schicht 17A getrennt ein Deckelinnenblech 18, so daß das Deckelinnenblech 18 die amorphe Siliziumschicht 12 nicht berührt. Das Deckelinnenblech 18 kann einstückig oder auch mehrteilig ausgebildet sein. Eine Dichtung (nicht gezeigt) kann - wie in der älteren Anmeldung P 42 38 889.9 dargestellt - als eingeclipstes Teil in den Außenrand des Einfaßrahmens 17 integriert werden. The single pane safety glass pane 11 is foamed in the outer region 13 in the form of a border frame 17 with polyurethane or a mixture of polyurethanes. In the foam, on the coated side of the glass pane 11 , a cover inner sheet 18 is separated by a plastic layer 17 A starting from the frame 17 , so that the cover inner sheet 18 does not touch the amorphous silicon layer 12 . The inner cover plate 18 can be formed in one piece or in several parts. A seal (not shown) can - as shown in the earlier application P 42 38 889.9 - be integrated as a clipped part in the outer edge of the frame 17 .
In Fig. 2 ist der lichtdurchlässige Scheibenaufbau 10 in Schäumlage in der Vorrichtung 20 dargestellt. Die Vorrichtung umfaßt ein Werkzeugoberteil 21 und ein Werkzeugunterteil 22. Im Werkzeugunterteil 22 ist eine erste Vakuumvorrichtung 23 vorgesehen, die den Scheibenaufbau 10 gegen das Werkzeugunterteil 22 zieht. Im Werkzeugoberteil 21 befindet sich eine zweite Vakuumvorrichtung 24, die das Deckelinnenblech 18 gegen das Werkzeugoberteil 21 zieht. Die erste Vakuumvorrichtung 23 umfaßt mehrere Vakuumsauger, die an der Außenseite der Einscheibensicherheitsglasscheibe 11 angreifen. Die zweite Vakuumvorrichtung 24 besteht aus einem Saugkanal 25 und einem Saugraum 26. Der Saugkanal 25 ist mit einer nicht dargestellten Unterdruckquelle verbunden und führt von außen durch das Werkzeugoberteil in den von Werkzeugoberteil 21 und Werkzeugunterteil 22 gebildeten Saugraum 26. Bei geschlossener Vorrichtung 20 ist der Saugraum 26 vom Werkzeugoberteil 21, zwei daran angeordneten Saugraumdichtungen 27, 28 und dem Deckelinnenblech 18 begrenzt. Eine Dichtung 29 im Werkzeugoberteil 21 liegt bei geschlossenem Werkzeug 20 und eingelegter Scheibe 10 am inneren Rand des Außenbereichs 13 der Scheibe 10.In Fig. 2 of the light transmissive disk structure is shown in Schäumlage in the device 20 10. The device comprises an upper tool part 21 and a lower tool part 22 . In the lower tool part 22 has a first vacuum device 23 is provided which pulls the disk assembly 10 against the lower tool part 22nd In the upper tool part 21 there is a second vacuum device 24 which pulls the inner cover plate 18 against the upper tool part 21 . The first vacuum device 23 comprises a plurality of vacuum suction cups which engage on the outside of the single-pane safety glass pane 11 . The second vacuum device 24 consists of a suction channel 25 and a suction space 26 . The suction channel 25 is connected to a vacuum source (not shown) and leads from the outside through the upper tool part into the suction space 26 formed by the upper tool part 21 and the lower tool part 22 . When the device 20 is closed, the suction chamber 26 is delimited by the upper tool part 21 , two suction chamber seals 27 , 28 arranged thereon and the inner cover plate 18 . A seal 29 in the upper tool part 21 lies when the tool 20 is closed and the disk 10 is inserted on the inner edge of the outer region 13 of the disk 10 .
Um einen umschäumten Scheibenaufbau 10 herzustellen, wird die beschichtete, im Durchsichtsbereich mit transparenter Klebefolie 15 und einer Abdeckung 16 versehene Einscheibensicherheitsglasscheibe 11 mit der späteren Scheibenaußenseite nach unten so in das Werkzeugunterteil 22 eingelegt, daß sie vom Vakuumsauger 23 angesaugt an den Randauflagestellen bündig abdichtet. Das Deckelinnenblech 18 wird in das Werkzeugoberteil 21 eingelegt und dort ebenfalls über Vakuum angesaugt. Zusätzlich oder auch alternativ zur Ansaugung kann das Deckelinnenblech 18 über Magnete oder mechanische Spannvorrichtungen gehalten werden (nicht dargestellt). Beim Schließen der Vorrichtung 20 dichtet das Werkzeugoberteil 21 mit dem Werkzeugunterteil 22 außen an der Trennkante zwischen beiden Werkzeugteilen 21, 22 sowie die Dichtung 29 auf der Abdeckung 16 am inneren Rand des Außenbereichs 13 des Scheibenaufbaus 10. Das Deckelinnenblech 18 wird durch die Lage der Saugraumdichtungen 27 und 28 in einem definierten Abstand zur amorphen Siliziumschicht 12 gehalten. Anschließend werden der Außenrand der Einscheibensicherheitsglasscheibe 11, der Außenrand der transparenten Abdeckung 16 und das Deckelinnenblech 18 mit Polyurethan zu einem Einfaßrahmen 17 umschäumt. Durch die Schicht 17A wird jede Verbindung zwischen Deckelinnenblech 18 und amorpher Siliziumschicht 12 durch Polyurethan unterbunden, sodaß die Solarzellen auch in den Außenbereichen 13 keine unerwünschte Verbindung zur Masse bekommen.In order to produce a foam-coated pane structure 10 , the coated single pane safety glass pane 11 , which is provided in the see-through area with transparent adhesive film 15 and a cover 16 , is placed with the later pane outside downward in the lower tool part 22 in such a way that it is sucked in by the vacuum suction device 23 at the edge support points. The inner cover plate 18 is inserted into the upper tool part 21 and also sucked in there by vacuum. Additionally or alternatively to the suction, the inner cover plate 18 can be held by magnets or mechanical tensioning devices (not shown). When the device 20 closes, the upper tool part 21 seals with the lower tool part 22 on the outside at the separating edge between the two tool parts 21 , 22 and the seal 29 on the cover 16 on the inner edge of the outer region 13 of the pane structure 10 . The inner cover plate 18 is held at a defined distance from the amorphous silicon layer 12 by the position of the suction chamber seals 27 and 28 . The outer edge of the toughened safety glass pane 11 , the outer edge of the transparent cover 16 and the inner cover plate 18 are then foamed with polyurethane to form a border frame 17 . The layer 17 A prevents any connection between the inner cover sheet 18 and the amorphous silicon layer 12 by means of polyurethane, so that the solar cells do not get any undesired connection to the ground even in the outer regions 13 .
Wenn auch mittels der Erfindung vorzugsweise ein transparenter Scheibenaufbau geschaffen werden soll, so ist es ebenso denkbar und vom Schutzanspruch mit umfaßt, wenigstens eine durchgehende Schicht aus undurchsichtigem amorphem Halbleiter material auf die gesamte Unterseite der Scheibe 11 aufzutragen. Die Herstellung eines solchen Scheibenaufbaus wird erleichtert und die Energieausbeute der derart geschaffenen Solarzellen ist bei gleicher Fläche entsprechend höher. Bei bestimmten Anwendungszwecken wird der Umstand der mangelnden Lichtdurchlässigkeit dieser Variante von untergeordneter Bedeutung sein.If, preferably, a transparent pane structure is to be created by means of the invention, it is also conceivable and covered by the protection claim to apply at least one continuous layer of opaque amorphous semiconductor material to the entire underside of the pane 11 . The manufacture of such a pane structure is facilitated and the energy yield of the solar cells created in this way is correspondingly higher for the same area. For certain applications, the fact that this variant is not translucent will be of minor importance.
