Höhere Wirkungsgrade im Tandem - neuer Solarzellenrekord

(PresseBox) (Freiburg, )
Die Photovoltaikforschung arbeitet mit Nachdruck daran, die Wirkungsgrade von Solarzellen immer weiter zu erhöhen. Zunehmend rückt die Tandem-Photovoltaik dabei in den Fokus, bei der in unterschiedlichen Kombinationen leistungsstarke Solarzellenmaterialien zusammengeführt werden, um so das Sonnenspektrum bei der Umwandlung von Licht in elektrische Energie noch effizienter zu nutzen. Das Fraunhofer ISE verzeichnet jetzt mit 25,9 Prozent Wirkungsgrad einen neuen Rekordwert für eine direkt auf Silicium gewachsene III-V/Si Tandemsolarzelle. Diese wurde erstmals auf einem kostengünstigen Siliciumsubstrat hergestellt – ein wichtiger Meilenstein auf dem Weg zu wirtschaftlichen Lösungen für die Tandem-Photovoltaik.
