25. We also note that the regeneration of the oxidized dye by the iodide redox electrolyte has received limited attention to date. This dye regeneration reaction also exhibits a dependence upon electrolyte composition and externally applied bias. (Nasr, C.; Hotchandani, S.; Kamat, P. V. J. Phys. Chem.

35. 2 cation state generated in solution. 4 Contributions to the transient data from dye-excited states can be neglected because of its relatively weak absorption at 800 nm and short excited-state lifetime (3-25 ns). We thus conclude that amplitude of the signal at 800 nm is primarily dominated by dye cation absorption.

37. Note that the changes observed because of the application of -0.8 V were not fully reversible, indicating possible dye degradation or desorption induced at this potential.

41. No dependence of electrolyte composition upon the injection yield was observed for any of electrolytes employed in mis study, determined both from the magnitude of the 800 nm signal observed on the nanosecond-millisecond time scales as reported here (to within ± 20% experimental error) and from ultrafast studies of the electron injection kinetics and yield.
42. Data shown were collected without adsorbed dye molecules; however, data collected with adsorbed dyes were indistinguishable, but this was limited to a smaller voltage range to avoid dye degradation.

44. It has been suggested that this modulation of Fermi level under applied bias is limited at low biases only to the film region adjacent to the conducting glass (ref 56). However, our own studies of this Fermi level distribution indicate that under our experimental conditions the Fermi level is distributed uniformly throughout the film. This issue will be addressed in detail elsewhere. Haque, S. A.; Klug, D. R.; Durrant, J. R., to be submitted for publication.
