Title: Electrodeposition of C{sub 60} cluster aggregates on nanostructured SnO{sub 2} films for enhanced photocurrent generation

Abstract

Clusters of C{sub 60} formed in acetonitrile (ACN)/toluene solutions are deposited as thin films on nanostructured SnO{sub 2} electrodes under the influence of an electric field. These films exhibit remarkable photoelectrochemical activity under visible light excitation. The photocurrent observed with these novel electrodes ({approximately}0.14 mA/cm{sup 2} obtained with visible light excitation, {lambda} > 425 nm, 130 mW/cm{sup 2}) is 2--3 orders of magnitude larger than previously reported values for a fullerene system. Direct electron transfer between the excited C{sub 60} clusters deposited on SnO{sub 2} nanocrystallites and the redox couple (I{sub 3}{sup {minus}}/I{sup {minus}}) in solution is responsible for the enhanced photocurrent generation.
