Multikristalline Siliciumsolarzelle mit 21,9 Prozent Wirkungsgrad

Weltrekord zurück am Fraunhofer ISE

(PresseBox) (Freiburg, )
Das Potenzial der Photovoltaik (PV) ist noch nicht ausgeschöpft, Industrie und Forschung arbeiten intensiv an der weiteren Effizienzsteigerung und Kostenreduktion für Solarzellen, dem Herzstück von PV-Kraftwerken. Für multikristallines Silicium, das Arbeitspferd der Solarzellenindustrie, haben die Forscher am Fraunhofer ISE jetzt einen Wirkungsgrad von 21,9 Prozent erreicht und damit den Weltrekord wieder nach Freiburg geholt.

Höhere Wirkungsgrade und optimierte Prozessschritte sind entscheidend, um den Preis für Solarstrom noch weiter zu senken. An beiden Stellschrauben arbeitet das Fraunhofer-Institut für Solare Energiesysteme ISE. Beim Wirkungsgrad verzeichnen die Freiburger Forscher jetzt einen neuen Weltrekord. Eine multikristalline Siliciumsolarzelle wandelt 21,9 Prozent des Sonnenlichts in elektrische Kjbwksk sh.
