Effect of Aging Time and Film Thickness on the Photoelectrochemical Properties of TiO2 Sol-Gel Photoanodes

Figure 4

Effect of aging time on the photocurrent of TiO2 sol-gel photoelectrodes: (a) SG/1 layer/0 h, (b) SG/1 layer/3 h, and (c) SG/1 layer/6 h. The effect of the thickness of TiO2 on the photocurrent density is also reported; see (d) SG/2 layers/6 h and (e) SG/3 layers/6 h.
