Abstract

We study the photovoltaic response of inorganic/organic composite devices containing the conjugated polymer, MEH-PPV, and a semi-transparent layer of titanium dioxide (TiO2) nanoparticles, which is similar to that employed in the Grätzel photoelectrochemical cell. Comparison of the photovoltage obtainable under illumination with either a Au, Ag, Al or Ca back electrode suggests that the built in potential is determined largely by the difference between the quasi Fermi level of the TiO2 under illumination and the work function of the back electrode. A qualitative model for charge generation and transport through the device is presented.
