Abstract

We are investigating the properties of corrole-sensitized TiO2 solar cells. The TiO2-adsorbed free base and GaIII 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 GaIII corroie, but not of the SnIV derivative, is sufficiently high for efficient injection into the TiO2 conduction band.
