Tandem-Photovoltaik ermöglicht Höhenflüge bei Wirkungsgraden - 35,9% für III-V//Silicium Solarzelle

(PresseBox) (Freiburg, )
Seit 40 Jahren betreibt das Fraunhofer ISE Spitzenforschung in der Photovoltaik, mit immer wieder neuen Rekordwirkungsgraden in unterschiedlichen Materialklassen und wichtigen Beiträgen zur Kostenreduzierung von Solarstrom, der heute die günstigste Form der Energiebereitstellung ist. Photovoltaik ist neben Windenergie die zentrale Säule der Energiewende. Mit dem Ziel, den Flächenbedarf und den Materialeinsatz von Solarmodulen noch weiter zu reduzieren, legt das Institut aktuell einen Fokus auf die Tandem-Photovoltaik, bei der durch die Verbindung unterschiedlicher Solarzellenmaterialien bisherige Effizienzgrenzen durchbrochen werden können. So gelang es den Freiburger Forscherinnen und Forschern jetzt, mit einer monolithischen Tandemzelle bestehend aus III-V-Halbleitern und Silicium einen neuen Weltrekord aufzustellen.
