IN ARTIKEL 19 (1) GENANNTE ERKLÄRUNG
Die Dl und D2 betreffen Photovoltaikelemente im Superstrataufbau, wobei auf der Frontseite des Substrates eine Lichtkonversionsschicht aufgebracht ist.
Die D3 betrifft eine Anordnung mit einer zwischen zwei Substraten eingekapselten Solarzelle, wobei auf den Substraten eine Konversionsschicht angeordnet ist. Es handelt sich also hier um eine ähnliche Lösung wie bei der D4, nur dass zwei gegenüberliegende Substrate zur Verkapselung vorgesehen sind.
Im Zusammenhang mit der D3 verweist der Recherchebericht darauf, dass in Absatz 41 offenbart sei, dass die gleiche Lösung auch für andere Solarzellen angewandt werden könne und der Fachmann daher die Lösung auch bei Dünnschichtmodulen in Betracht ziehen würde. Dieser Folgerung ist zu widerspechen, da in Abschnitt [0041] wörtlich angegeben ist:„In the illustrated embodiment, the PV cells 104 are pn-junction devices formed from thin slices or strips of crystalline Silicon. However, the PV cells 104 can also be formed from another suitable photoactive material". Zwar würde der Fachmann in Betracht ziehen, statt der eingekapselten kristallinen Solarzellen Dünnschichtsolarzellen einzukapseln, jedoch würde er den Gesamtaufbau nicht in einen Suberstrataufbau umwandeln, also die Einkapselung weglassen.
Die D5 und D6 beschreiben normale Substrataufbauten mit einer direkt auf der Solarzelle angeordneten Konversionsschicht.
Gegenüber der Dl , die zeigt, dass das Substrat einer Superstrat-Solarzelle mit einer Konversionsschicht beschichtet ist, bestehen sowohl hinsichtlich des Verfahrens als auch hinsichtlich des photo- voltaischen Elementes deutliche Unterschiede dahingehend, dass die Konversionsschicht 1 kein Verkapselungselement im Sinne der vorliegenden Patentanmeldung ist, das also die Solarzelle und die Konversionspartikel vor Witterungseinflüssen schützt. 18
In der D2 ist in Abschnitt [0026] zwar offenbart, dass das Luminiszensmaterial auch einen Klebstoff umfasst, allerdings offenbart die D2 nicht die Merkmale des Kennzeichens von Anspruch 1 und legt diese auch nicht nahe.
Außerdem beschreibt die D2 ein völlig anderes Verfahren, da die Schicht 26 auf dem Substrat mittels eines Beschichtungsprozesses aufgebracht und ausgehärtet wird, wie auch aus Fig. 4 und der zugehörigen Beschreibung in den Abschnitten [0033] bis [0038] eindeutig hervorgeht. Die D2 beschriebt als kein Verkapselungselement, das als solches, also fertig, bereitgestellt und auf der Solarzelle aufgebracht wird.
Mit dem Verfahren der D2 sind im übrigen Nachteile verbunden, die schon in der vorliegenden Patentanmeldung beschrieben sind. Hierzu ist im 3. Absatz auf Seite 1 angegeben, dass durch Aufbringen auf eine Solarzelle eingebettet in ein geeignetes Trägermaterial, beispielsweise als Gel, Emulsion oder Folie, die Energieaufnahme der Solarzelle und damit ihr Wirkungsgrad erhöht werden könnte. Einem standardisierten Einsatz stehen jedoch derzeit noch technische Probleme entgegen. Die derzeitig verwendeten Materialien weisen nicht die nötige Witterungsbeständigkeit auf .... Ein einfaches Aufbringen auf die Sonnenseite der Solarzelle ist daher nicht möglich." Somit ist schon in der vorliegenden Patentanmeldung beschrieben, dass die Lösung der D2 keine Langzeitstabilität ermöglicht.
Mit dem neuen Anspruchsatz ist nunmehr klargestellt, dass das Verkapselungselement, dass eine Konversionsschicht aufweist, abhängig von der Superstrat-Solarzelle hergestellt und anschließend darauf aufgebracht wird, also die wechselweise Beeinflussung von Solarzelle und Konversionsschicht so gering wie möglich im Produktionsprozess gehalten wird.
Dieser erfindungsgemäße Gegenstand ist aus dem Stand der Technik weder bekannt noch dem Fachmann irgendwie nahe gelegt.
