Abstract
We used water-based solutions of commercial nanocrystalline titanium oxide (P25) powder and gel (Nanoxide D) to prepare a mesoporous photoelectrodes for the fabrication of dye-sensitized solar cells (DSSC). By varying the thicknesses of the titanium oxide electrodes and the compact layer, the condition of the TiCl4 and 4-tert-butylpyridine (4-TBP) treatments, the annealing temperature, the species of the dye, the solvent of the electrolyte, and the thickness of the platinum counter electrodes, we analyzed the influences of the variant conditions on DSSC performances. Characterizations were performed with SEM, XRD, surface profiling, current-voltage characteristics, spectrum response and impedance spectroscopy. The best light-to-electric-energy conversion efficiencies of solar cells based on Nanoxide D is 6.49% (Voc=0.68 V, Jsc=16.26 mA/cm2, fill factor=0.59) at 1 sun illumination (AM1.5, 100 mW/cm2) and 5.23% (Voc=0.66 V, Jsc=13.76 mA/cm2, fill factor=0.58) at 1 sun illumination (AM1.5, 100 mW/cm2) for solar cells based on P25.
