Photoelectrochemical cell based on cup-shaped nanocarbon-fullerene composite nanocluster film: Enhancement of photocurrent generation by cup-shaped nanocarbons as an electron transporter

Abstract

Cup-shaped nanocarbons and fullerene (C60) have been successfully organized as composite nanoclusters by using a rapid solvent mixing method. The resulting clusters were assembled on the nanostructured SnO 2 electrode for photoelectrochemical measurements. This composite cluster film electrode afforded the drastic enhancement in the photoelectrochemical performance as well as the broader photoresponse in the visible region as compared with the reference system containing C60 cluster because of the efficient electron transport ability of cup-shaped nanocarbons. This makes cup-shaped nanocarbon materials a promising candidate for developing efficient photoelectrochemical and photovoltaic cells. Copyright © 2010 Taylor & Francis Group, LLC.
