N-doped TiO2 nanotubes are synthesized by alkaline hydrothermal and reflux method. Formation of TiO2 nanotube morphology and anatase phase is shown by TEM, XRD, Raman. Coordination of NH4+ via TiONH4+ or H4N+TiO bonds is indicated by FT-IR and XPS. Blocking effect of N-doped toward electron transfer on TiO2 anode is studied by CV. N-doped TiO2 improved DSC performance up to 30–40% mainly due to an increase in Jsc.
