Abstract
Titania nanofibers (NFs) and nanorods (NRs) with different diameters were prepared by electrospinning method. Photovoltaic properties of NR photoelectrodes were investigated with FESEM microscope, spectrophotometer and photovoltaic devices. It is found that titania NR electrodes with the diameter of 193 nm had the best conversion efficiency. Electrochemical modelings demonstrated the electron behaviors of anode layer and electrolyte. It is also determined that titania NR electrode with the diameter of 193 nm had the maximum electron life time value of 3.6 mS, the most chemical capacitance (Cµ) of 166.16 µF and the least recombination resistance (Rtr) of 705.3 Ω.
Keywords: Dye sensitized solar cells, nanorod, nanostructure, thin-film.
