Self-Organized One-Dimensional TiO𝟐 Nanotube/Nanowire Array Films for Use in Excitonic Solar Cells: A Review

Figure 6

(a) Current-voltage characteristics and (b) the overall conversion efficiency of solid-state photovoltaic devices made using P3HT/PCBM-coated TiO2 nanotubes. Five curves, 1 to 5, represent five different TiO2 surface treatments before polymer blend spin coating. Treatment of nanotubes for (1) Curve 1—TBP, (2) Curve 2—CB, (3) Curve 3—o-DCB, (4) Curve 4—soaked in o-DCB, and (5) Curve 5—soaked in o-DCB and baked at 165°C. Curves 1 to 4 were baked at 150°C.
