Figure 5: Photocurrent action spectra obtained with complexes A1 and A3 with and without DCA addition during the sensitization process. Incident photon-to-current conversion efficiency is plotted as a function of wavelength. A sandwich type sealed cell configuration was used to measure this spectrum. The electrolyte composition was 0.6 M DMPII, 0.05 M I2, and 0.1 M LiI in acetonitrile.
