Fraunhofer Forscher erhalten Deutsch-Französischen Wirtschaftspreis 2011

(PresseBox) (Freiburg, )
Forscher des Fraunhofer ISE entwickeln gemeinsam mit ihren französischen Kollegen des Carnot-Instituts Laboratoire d'électronique des technologies de l'information CEA-LETI wiederverwendbare Substrate für III-V Mehrfachsolarzellen - und erhielten dafür am 5. Dezember 2011 den deutsch-französischen Wirtschaftspreis 2011.

Die Photovoltaik boomt - auf den Dächern werden immer mehr Solarmodule angebracht, und auch große Sonnen-Kraftwerke speisen zunehmend Strom ins Netz ein. Besonders effizient sind Mehrfachsolarzellen: Sie erzielen Wirkungsgrade von bis zu 43 Prozent, also fast doppelt so viel wie herkömmliche Solarzellen aus kristallinem Silizium. Der Trick: Sie bestehen aus mehreren Halbleiterschichten, die zusammen das gesamte Sonnenspektrum in elektrische Energie umwandeln. Eingesetzt wird cqf Ttduscx hv qps Ujjgtaexgywe-Qenfwpbzvssl.
