Abstract

Nanocrystalline thin SnO2 semiconductor films (thickness≤1 μm) have been modified with chlorophyll b (Chl-b) by electrodeposition and adsorption methods for use as novel photosensitive electrodes in photoelectrochemical cells. Excitation of Chl-b with monochromatic light produced photocurrents with an incident photon-to-photocurrent efficiency of around 8.5%. The charge injection from excited Chl-b into the conduction band of the semiconductor SnO2 crystallites has been probed by time-resolved microwave absorption.
