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

Figure 13

IPCE spectra of four hybrid solar cell device structures, namely, FTO/TiO₂ nanotube array/SK-1, SK-2, SQ-1, or no dye layer/P3HT/PEDOT:PSS/Au. The dye sensitization and PEDOT:PSS layer are identical in the four samples. Reprinted with permission from [51].
