Abstract

A novel approach to solar energy conversion is presented on the basis of photoinduced heterogeneous electron transfer at polarised interfaces between two immiscible electrolyte solutions. Preliminary studies at the water\ 1,2-dichloroethane interface sensitised by water-soluble zinc porphyrin heterodimers exhibited conversion efficiencies around 0.1%, corresponding to a photocurrent to absorbed photon flux ratio close to unity. The conversion efficiency is increased in the presence of redox couples acting as supersensitiser in the aqueous phase. The characteristic power relationship for these interfaces is also presented, surd the possibility of solar cells where no solid electrodes are directly involved in the photogeneration and transport of charge carriers is envisaged.
