Description
Die Erfindung betrifft ein Kraftwagenbauteil mit zumindest einem photovoltaischen Element nach dem Oberbegriff von Patentanspruch 1 sowie ein Verfahren zu dessen Herstellung nach dem Oberbegriff von Patentanspruch 3.The invention relates to a motor vehicle component with at least one photovoltaic element according to the preamble of
Aus der
Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde ein Kraftwagenbauteil nach dem Oberbegriff von Patentanspruch 1 sowie ein Verfahren zu dessen Herstellung nach dem Oberbegriff von Patentanspruch 3 so weiter zu entwickeln, dass eine verbesserte Integration photovoltaischer Elemente in Kraftwagenbauteile ermöglicht wird.The present invention is therefore the object of a motor vehicle component according to the preamble of
Diese Aufgabe wird durch ein Kraftwagenbauteil mit den Merkmalen des Patentanspruchs 1 sowie durch ein Verfahren zum Herstellen eines Kraftwagenbauteils mit den Merkmalen des Patentanspruchs 3 gelöst.This object is achieved by a motor vehicle component having the features of
Ein solches Kraftwagenbauteil weist wenigstens ein photovoltaisches Element auf, welches über wenigstens eine Leiterbahn und/oder wenigstens ein Kontaktierungselement mit einem elektrischen Verbraucher, insbesondere einem Bordnetz des Kraftwagens, verbindbar ist. Erfindungsgemäß ist vorgesehen, dass die wenigstens eine Leiterbahn und/oder das wenigstens eine Kontaktierungselement als mikrostrukturierte Oberflächenstruktur des Bauteils ausgebildet ist, welche aus einzelnen Pixeln aus einem leitfähigen Material aufgebaut ist. Mit anderen Worten ist die Leiterbahn und/oder das Kontaktierungselement direkt in das Bauteil integriert, so dass diese elektrischen Strukturen nicht in Form einer Folie oder dergleichen bereitgestellt werden müssen. Durch die Integration von Leiterbahnen und/oder Kontaktierungselementen direkt an das Kraftwagenbauteil wird eine besonders belastbare elektrische Struktur geschaffen, die auch den Belastungen im Betrieb des Kraftwagens stand zu halten vermag. Durch das Aufbringen der Leiterbahn und/oder des Kontaktierungselements in Form einzelner Pixel ist eine besonders flexible Fertigung solcher Kraftwagenbauteile möglich. Anordnung und Verlauf von Leiterbahnen und/oder Kontaktierungselementen können durch eine derartige Technik problemlos an unterschiedliche Formen des Kraftwagenbauteils oder unterschiedliche Anordnungen von photovoltaischen Elementen angepasst werden.Such a motor vehicle component has at least one photovoltaic element which can be connected via at least one conductor track and / or at least one contacting element to an electrical consumer, in particular a vehicle electrical system of the motor vehicle. According to the invention it is provided that the at least one conductor track and / or the at least one contacting element is formed as a microstructured surface structure of the component, which is constructed from individual pixels of a conductive material. In other words, the conductor track and / or the contacting element is integrated directly into the component, so that these electrical structures do not have to be provided in the form of a foil or the like. The integration of printed conductors and / or contacting elements directly to the motor vehicle component, a particularly resilient electrical structure is created, which is able to withstand the stresses during operation of the motor vehicle. By applying the conductor track and / or the contacting element in the form of individual pixels, a particularly flexible production of such motor vehicle components is possible. Arrangement and course of conductor tracks and / or contacting elements can be easily adapted by such a technique to different forms of the motor vehicle component or different arrangements of photovoltaic elements.
Bevorzugt überlappt jedes Pixel der wenigstens einen Leiterbahn und/oder des wenigstens einen Kontaktierungselements mit wenigstens einem benachbarten Pixel. Hierdurch können beliebige flächige elektrisch leitfähige Strukturen geschaffen werden.Each pixel of the at least one interconnect and / or of the at least one contacting element preferably overlaps with at least one adjacent pixel. As a result, any planar electrically conductive structures can be created.
Die Erfindung betrifft weiterhin ein Verfahren zum Herstellen eines Kraftwagenbauteils mit zumindest einem photovoltaischen Element. Bei einem erfindungsgemäßen Verfahren wird wenigstens eine Leiterbahn und/oder wenigstens ein Kontaktierungselement zum Kontaktieren des photovoltaischen Elements mittels eines Druckverfahrens in Form einzelner Pixel aus einem leitfähigen Material auf eine Oberfläche des Bauteils aufgedruckt. Diese sogenannte Pixeltechnik wird z. B. in der
Als Druckverfahren zum Aufdrucken der einzelnen Pixel können druckformbasierte Verfahren, wie zum Beispiel Siebdruck, Trommeldruck oder Tampondruck verwendet werden. Alternativ sind auch druckkopfbasierte Verfahren einsetzbar. Hierbei kann es sich um druckkopfbasierte Verfahren mit kontinuierlichem Tropfenstrom oder mit diskontinuierlichen Tropfenstrom handeln, bei welchem die Einzeltropfen mechanisch oder thermisch erzeugt werden. Gerade mit solchen druckkopfbasierten Verfahren ist eine besonders flexible Gestaltung elektrischer Elemente auch auf komplex geformten Kraftwagenbauteilen möglich, da der Druckkopf bei einem solchen Verfahren in beliebigen Raumkurven geführt werden kann. Dies kann besonders vorteilhaft mit einem Druckkopf erfolgen wie er in der
In weiterer Ausgestaltung der Erfindung wird das Kraftwagenbauteil nach dem Aufdrucken der wenigstens einen Leiterbahn und/oder des wenigstens einen Kontaktierungselements einer thermischen Nachbehandlung unterzogen, bei welcher das Material der Pixel wenigstens teilweise aufgeschmolzen und/oder ausgehärtet wird. Durch ein teilweises Aufschmelzen der Pixel kann deren Überlappung verbessert werden, so dass der Innenwiderstand derart erzeugter Leiterbahnen und/oder Kontaktierungselemente besonders niedrig ist. Durch das Aushärten des Materials der Pixel werden besonders haltbare elektrische Strukturen geschaffen.In a further embodiment of the invention, after printing the at least one printed conductor and / or the at least one contacting element, the motor vehicle component is subjected to a thermal after-treatment in which the material of the pixels is at least partially melted and / or hardened. By partially melting the pixels, their overlap can be improved, so that the internal resistance is such produced conductor tracks and / or contacting elements is particularly low. By curing the material of the pixels, particularly durable electrical structures are created.
Alternativ oder additiv kann im Bedarfsfall die Haftung der Pixeln auf der Bauteiloberfläche verbessert werden, z. B. mittels einer Plasmaaktivierung der Bauteiloberfläche.Alternatively or additionally, the adhesion of the pixels on the component surface can be improved if necessary, for. B. by means of a plasma activation of the component surface.
In bevorzugter Ausgestaltung des erfindungsgemäßen Verfahrens wird abschließend noch eine Schutzschicht aufgebracht. Dies kann ebenfalls drucktechnisch erfolgen, aber z. B. auch durch Bedampfen oder Tauchen. Geeignete Schichten bestehen z. B. aus handelsüblichem Klarlack.In a preferred embodiment of the method according to the invention, finally, a protective layer is applied. This can also be done by printing, but z. B. also by steaming or dipping. Suitable layers consist for. B. from commercial clearcoat.
Im Folgenden soll die Erfindung und ihre Ausführungsformen anhand der Zeichnung näher erläutert werden. Hierbei zeigen:In the following, the invention and its embodiments will be explained in more detail with reference to the drawing. Hereby show:
