Figure 10

(a) Typical cross-sectional view of 60โ€‰nm pore size, 1โ€“1.2โ€‰ฮผm length TiO2 nanotube array film after TiCl4 treatment. Cross-sectional FESEM image of TiO2 nanotube (โ‰ˆ35โ€‰nm pore size, โ‰ˆ600โ€“700โ€‰nm nanotube length)/SQ-1 dye/P3HT/PEDOT:PSS photovoltaic devices showing: (b) nanotubes partially infiltrated with polymer, fabricated under the condition of excess wetness; (c) fully infiltrated nanotubes fabricated under optimized wetness condition; and (d) partial infiltration of the P3HT polymer within the nanotubes, fabricated under dry condition.
