Effects of Titanium Oxide Nanotube Arrays with Different Lengths on the Characteristics of Dye-Sensitized Solar Cells

Figure 5

Absorption spectra of TNT arrays sensitized with N-719 dye at various TNT-array lengths produced with 0.5 wt% NH4F concentration, under simulated AM-1.5 solar illumination (100 mW cm−2) and active area 0.28 cm2.
