Sample Photoelectrode Thickness of the TiO2 nanotubes (μm) Jsc Voc FF Efficiency (%)
(mA/cm2) (V)
(a) Bare 1.5 3.279 0.636 0.549 1.147 ± 0.167
(b) Micro-flowers 1.5 3.838 0.661 0.467 1.187 ± 0.041
(c) Bare 2.0 4.030 0.636 0.536 1.378 ± 0.092
(d) Micro-flowers 2.0 4.340 0.644 0.542 1.517 ± 0.063

The thicknesses of TiO2 nanotubes are 1.5 μm and 2.0 μm.
