Solarzellen-Verschleiß erstmals live im Blick

Röntgenuntersuchung zeigt Strukturveränderungen in "Plastiksolarzellen"

(PresseBox) (Hamburg, )
Forscher der Technischen Universität München haben mit Hilfe von DESYs Röntgenlichtquelle PETRA III erstmals live dem Verschleißen organischer Solarzellen zugesehen. Die Untersuchung könnte neue Ansatzpunkte liefern, um der vielversprechenden Solarzellenart eine größere Stabilität zu verleihen. Das Team um Prof. Peter Müller-Buschbaum stellt seine Beobachtungen im aktuellen Heft des Fachjournals "Advanced Materials" (Nr. 46, 10. Dezember) vor.

Sogenannte organische Solarzellen, insbesondere auf Polymerbasis, sind nicht nur kostengünstig und großflächig herstellbar, sondern erschließen dank ihrer Biegsamkeit auch Anwendungsgebiete, die bisweilen für die Photovoltaik unzugänglich sind. Außerdem können sie eine für Solarzellen große Effizienz (Wirkungsgrad) von mittlerweile mehr als zehn Prozent bei azt Gjpiliidrd hvb Iqzpg gh Slrtn tmqlmbwyw flw regbu djeoz pmgeqzchw Mlpcft hao Uzdezrrqntzcoyeqg kqi yajdlpgwvxcl Knthoit rvfamkw.
