Abstract

Intensity modulated photovoltage and photocurrent spectroscopies reveal that photoanodes based on nanorod arrays exhibit dramatically faster electron transport while retaining similar electron lifetimes (recombination times) compared to standard photoanodes assembled from colloidal nanoparticles.
