Abstract

original image

Fasern aus Kohlenstoffnanoröhren (CNTs) wurden um einen mehrere Zentimeter langen TiO2-Nanodraht gewunden. Durch Behandeln der Draht-Enden mit einem lichtempfindlichen Farbstoff bzw. einem Elektrolyten lassen sich Bereiche für die Photostromwandlung und Energiespeicherung in ein und derselben Funktionseinheit erzeugen (siehe Schema). Der Draht zeigt eine hohe Photostromwandlung und Speichereffizienz von 1.5 %.
