Flexible Solarzellen mit Rekordwirkungsgrad von 22,2%

Energieausbeute erneut gesteigert

(PresseBox) (Dübendorf, )
Ein Jahr nach ihrem letzten Wirkungsgradrekord haben Empa-Wissenschaftlerinnen und -Wissenschaftler einen neuen Höchstwert von 22,2% für flexible CIGS-Solarzellen auf Plastikfolien erreicht. Solarzellen dieses Typs eignen sich besonders für Anwendungen auf Gebäuden, Fahrzeugen, Satelliten, Luftschiffen und mobilen Geräten.

Die Empa-Forschenden haben den Wirkungsgrad von flexiblen CIGS-Solarzellen erneut verbessert. Unabhängig zertifizierte Messungen ergaben einen Wert von 22,2% bei der Umwandlung von Licht in Strom, was eine Verbesserung gegenüber dem bisherigen Rekordwert von 21,4% bedeutet. Zum Vergleich: Der maximale Wirkungsgrad einer starren Solarzelle aus kristallinem Silizium liegt bei 26,7%.
