Extensive research in this laboratory has focused upon a variety of tri- and tetravalent metal phthalocyanine compounds to be used as electrode materials in possible photovoltaic device applications. The thin-film electrodes with thicknesses on the order of one micron are fabricated from vanadyl phthalocyanine (VOPc) by sublimation upon gold coated, metallized plastic optically transparent electrodes. After numerous attempts in achieving the optimum growth conditions with chlorogallium phthalocyanine, it was found that the most photoactive films were grown at rates which required 24 to 72 hours to prepare a film with a thickness on the order of one micron. The most effective VOPc films were grown at slightly accelerated rates which required approximately 3 hours with thicknesses of the same dimensions. The films were then studied using cyclic voltammetry and a variety of redox couples with and without illumination in order to map out the energetics of the system.
