Auf dem Weg zu billigerem Solarstrom

Innovationspreis Mikroelektronik geht an Fraunhofer IISB und SolarWorld AG

(PresseBox) (Erlangen, )
Gemeinsam haben Forscher des Fraunhofer IISB Erlangen, des Fraunhofer THM Freiberg und der SolarWorld AG herausgefunden, wie sie durch den Einsatz von Magnetfeldern bei der industriellen Produktion von Siliziumkristallen für die Photovoltaik spezielle Materialfehler vermeiden können. Diese Materialfehler sind schädlich für die Anwendung der Kristalle zur Erzeugung von Solarstrom. Für die gemeinsamen Forschungs- und Entwicklungsarbeiten wurde den Forschern am 15. Oktober 2009 der Georg Waeber Innovationspreis 2009 des Förderkreises für die Mikroelektronik e.V. verliehen.

Die Photovoltaik basiert heute und auch in Zukunft auf kristallinen Siliziumsolarzellen. Für deren Herstellung werden kostengünstige Siliziumkristalle mit maßgeschneiderten Eigenschaften benötigt, aus denen dünne Scheiben ("Wafer") fzn zbz Xtvfntxtnaglfscxtsxh yajdjluqjno migaou.
