“…For example, Kao et al, got less than 60% transmittance for the 2 m thickness TiO 2 films prepared by a chemical method. 24 The refractive index of the nanorod TiO 2 and Flat TiO 2 have been obtained by fitting the transmittance as shown in Figure 6. The flat TiO 2 film has a dense structure and then a high refractive index.…”

For the first time, the TiO 2 nanorod arrays have been prepared on ITO substrates at room temperature by dc reactive magnetron sputtering technique. These TiO 2 nanorods have a preferred orientation along the (220) direction and are perpendicular to the ITO substrate. Both the X-ray diffraction and Raman scattering measurements show that the highly ordered TiO 2 nanorod arrays have an anatase crystal structure. The diameter of the nanorod varies from 30 nm to 100 nm and the nanorod length can be varied from several hundred nanometers to several micrometers depending on the deposition time. The TiO 2 nanorod arrays with about 3 micrometers length have been used as an electrode for dye-sensitized solar cell (DSSC). Short-circuit photocurrent density, opencircuit voltage, fill factor and light-to-electricity conversion efficiency at 100 mW/cm 2 light intensity are estimated to be 12.76 mA/cm 2 , 0.65 V, 0.63 and 5.25%, respectively, for the DSSC made of the TiO 2 nanorods.

“…A typical DSSC consists of a nanoporous metal oxide film such as TiO 2 , sensitizing dye, redox electrolyte and a counter electrode (O'Regan et al, 1991). The metal oxide film plays a major role in the enhancement of power conversion efficiency of DSSCs and many studies have been focused on the dependence of cell efficiency on film structure and thickness (Kang et al, 2004, Mathew et al, 2011, Kao et al, 2009. A significantly higher power conversion efficiency and incident photon to current conversion efficiency (IPCE) can be expected using TiO 2 photoanode with optimized film thickness, better crystallization and optimized microstructure.…”

Nanocrystalline titanium dioxide (TiO 2 ) photoanodes with four different film thicknesses from 5.57µm to 20.65µm were prepared by doctor-blade technique. Performance of dye sensitized solar cells (DSSCs) fabricated with these photoanodes were studied using current-voltage characteristics and incident photon-to-current conversion efficiency (IPCE) measurements. Electrochemical impedance spectroscopy (EIS) was used to analyze the effect of TiO 2 film thickness on the charge transfer resistance and electron life time in the solar cells. Voltage decay measurements were used to study the recombination process of photo generated charge carriers. These studies revealed that the photovoltaic properties of DSSCs largely depend on the film thickness of TiO 2 photoanode. Further, the DSSCs fabricated using a TiO 2 film of 12.73 µm thickness exhibited the best photovoltaic performance with highest incident photon-to-current conversion efficiency, highest short-circuit photocurrent, lowest charge transfer resistance, highest electron life time and lowest recombination life time.

Dye sensitized solar cell (DSSC) shows great promise as an alternative to conventional p-n junction solar cells due to their low fabrication cost and reasonably high efficiency. DSSC was assembled by using natural dye extracted from red amaranth (Amaranthus Gangeticus) as a sensitizer and different catalysts for counter electrode were applied for maximum energy conversion efficiency. Annealing temperature and thickness of electrode were also investigated and optimized. Catalyst, annealing temperature and thickness were optimized by the determination of cell performance considering photoelectrochemical output and measuring current and voltage; then calculating efficiency and other electrical parameters. The experimental results indicated that samples having 40 µm electrode thickness and prepared at 450 °C annealing temperature showed the best performance.
