Abstract

original image

Anbändelungsversuche mit Nanoröhren: Werden mehrwandige Kohlenstoff-Nanoröhren teilweise aufgerollt, entstehen verbrückende Nanobänder zwischen den Nanoröhren. Das resultierende System begünstigt einen schnellen Ladungstransport bei Verwendung als Gegenelektrode in Farbstoff-sensibilisierten Solarzellen. Die maximale Energieumwandlungseffizienz beträgt 8.23 % gegenüber 7.61 % für eine herkömmliche Platinelektrode.
