(a) Comparison of J–V curve for the [Co(bpy-pz)2]3+/2+ (red lines) and I3−/I− (black lines). (b) Photo-current dynamics as a function of light intensity for the [Co(bpy-pz)2]3+/2+ (red lines) and I3−/I− (black lines). (c) Comparison of IPCE spectra using TiO2 film thickness is 5.6 μm and [Co(bpy-pz)2]3+/2+ (red lines) and I3−/I− (black lines) redox systems.
