Forschung im Bereich der Organischen Photovoltaik arbeitet mit Nachdruck daran, die Wirkungsgrade weiter zu erhöhen. Neue Materialien aus der synthetischen organischen Chemie haben in den letzten Jahren deutliche Steigerungen des Wirkungsgrads ermöglicht. Eine der Herausforderungen ist dabei, die oftmals auf sehr kleinen Laborzellen erzielten Werte auf größere Flächen zu übertragen. Das Fraunhofer ISE verzeichnet jetzt zusammen mit dem Freiburger Materialforschungszentrum FMF der Universität Freiburg mit 14,9% einen Rekordwert für organische Solarzellen mit mindestens 1 cm2 Fläche – ein wichtiger Schritt für die Weiterentwicklung dieser kostengünstigen Technologie hin zu einer breiten Anwendungsreife.
