Weltrekord wieder beim HZB: Fast 30 % Wirkungsgrad bei Tandemsolarzellen der nächsten Generation

(PresseBox) (Berlin, )
Drei HZB-Teams unter der Leitung von Prof. Christiane Becker, Prof. Bernd Stannowski und Prof. Steve Albrecht haben es gemeinsam geschafft, den Wirkungsgrad von komplett in-house hergestellten Perowskit-Silizium-Tandemsolarzellen auf den neuen Rekordwert von 29,80 % zu steigern. Der Wert ist nun offiziell zertifiziert und in den NREL-Charts verzeichnet. Damit rückt die 30-Prozent-Marke in greifbare Nähe.

Heutige Solarmodule werden hauptsächlich aus Silizium hergestellt, Möglichkeiten für weitere Steigerungen des Wirkungsgrads sind bereits weitgehend ausgereizt. Doch seit 2008 ist die Materialklasse der "Metallhalogenid-Perowskite" in den Fokus der Forschung gerückt: diese Halbleiterverbindungen wandeln das Sonnenlicht überaus effizient in elektrische Energie um und bieten noch viel Zmav wjt Ubyepgvqphfnen.
