Abstract

We are investigating the properties of corrole-sensitized TiO₂ solar cells. The TiO₂-adsorbed free base and Ga^III corroies display cell efficiencies under AM 1.5 illumination that are about half that of a standard N3-sensitized cell (N3 = cis-bis(4,4′-dicarboxy-2, 2′-bipyridine)dithiocyanato ruthenium(II)), while that of the Sn ^IV-based cell is much lower. The properties of the corrole-TiO ₂ solar cells, along with results obtained with electrodes of lower conduction band energies clearly reveal that the reducing power of the singlet excited states of the free base and Ga^III corroie, but not of the Sn^IV derivative, is sufficiently high for efficient injection into the TiO₂ conduction band.
