Affection of Post-Nitrogen-Doping of TiO2 Nanoparticle Film Photo-Anode on Performance of Dye-Sensitized Solar Cells

A nitrogen-doped titania nanoparticle film on an ITO substrate was successfully obtained by gas phase method. Such a nitrogen-doped titania nanoparticle film on an ITO substrate shows efficient at the responsivity under the visible light exposure. TiO2 photo-anode with N-doped was fabricated using nanocrystalline pastes and their N719-sensitization led to a short-circuit photocurrent density of 3.95 mA/cm2 and a solar energy conversion efficiency of 1.72% under air-mass 1.5 global and illumination with the intensity of 100 mW/cm2 (AM 1.5G, 100 mW/cm2).
