Self-Organized One-Dimensional TiO_𝟐 Nanotube/Nanowire Array Films for Use in Excitonic Solar Cells: A Review

Figure 9

Optical absorbance of SK-1-, SK-2-, and SQ-1-sensitized TiO₂ nanotube arrays, and P3HT intercalated nanotube arrays without dye sensitization. The nanotube arrays had an average pore size of 35 nm and tube length of 600–700 nm. Reprinted with permission from [7, 51].
