Effect of Aging Time and Film Thickness on the Photoelectrochemical Properties of TiO2 Sol-Gel Photoanodes
Figure 6
(a) Showing the mesoporosity of the SG photoelectrodes and (b) the view of a SG/3 layers/6 h photoelectrode. The mesoporosity of the film allows good penetration of the electrolyte within the film and it is likely to be responsible for the good photoactivity shown by the SG photoanodes.
