20 Prozent Wirkungsgrad in Sicht für industrienahe Siliciumsolarzellen

(PresseBox) (Freiburg, )
Forschern des Fraunhofer-Instituts für Solare Energiesysteme ISE ist es gelungen, neue Spitzen-Wirkungsgrade für einfach herzustellende großflächige Siliciumsolarzellen zu erreichen.

Mit gegenüber dem heutigen Industriestandard weiter entwickelten Zellstrukturen konnten sie demonstrieren, dass in naher Zukunft Wirkungsgrade von 20 Prozent realisierbar sind.

Mehr als 80 Prozent der zur Zeit hergestellten Solarzellenleistung basiert auf kristallinem Silicium. Ziel von Industrie und Forschung ist es, die Kostenoptimierung für dieses Arbeitspferd der Photovoltaik weiter voranzutreiben.

Wandeln derzeit die Zellen durchschnittlich 14-19 Prozent des Sonnenlichts in elektrische Energie um, so haben die Forscher die 20-Prozent-Marke bereits im Blick.
