The critical material of photo-anode, the TiO2nano-particles, as the most important component in dye sensitized solar cells (DSSCs) was studied in this paper. The TiO2nanoparticles were prepared by the method of micro-emulsion. In the process of preparation, the factors including the kinds of surfactant, and the molar ratio of water to titanium (R value) were investigated. Finally, the optimal condition for the preparation of the TiO2nano-particles was determined. When Tx-100 was used as the surfactant and R was 35, the TiO2nano-particles were prepared and used as photo-anode in the DSSCs, which were sensitized by N719, test under AM1.5G sunlight. The highest photoelectric conversion efficiency was achieved: Short-circuit photocurrent (Isc) =13.91mA/cm2, open-circuit photo voltage (Voc) =0.83V, fill factor (FF) =55.06%, photoelectric conversion efficiency (η) =6.36%.

Sensitized Solar Cells

Recently, dye-sensitized solar cells (DSSC) have concerned significant attention attributable to their material preparation process, architectural and environmental compatibility, also low cost and effective photoelectric conversion efficiency. Therefore, this study aimed to use potential plant materials for DSSC. This research presents the extraction of natural pigments from yellow cotton flowers (Cochlospermum regium). In addition, the natural pigments were revealed that outstanding advantages, including a wide absorption range (visible light), easy extraction method, safe, innocuous pigments, inexpensive, complete biodegradation and ecofriendly. Methanol was used as a solvent extraction for the yellow cotton flower. The chlorophylls and carotenoid pigments extractions were estimated by a UV-visible spectrometer. The chlorophyll-a, chlorophyll-b, and carotenoid yield were 0.719±0.061 µg/ml, 1.484±0.107 µg/ml and 7.743±0.141 µg/ml, respectively. Thus, this study results suggested that yellow cotton flowers containing reasonable amounts appealable in the DSSC production.

Sensitized Solar Cells

TiO2 hollow spheres were successfully synthesized using poly styrene as the template. Dyesensitized solar cells are fabricated based on double-layered composite films of TiO2 nanoparticles and TiO2 hollow spheres. The photoelectric conversion performances of Dye-sensitized solar cells based on TiO2 nanoparticles/TiO2 nanoparticles, TiO2 nanoparticles/TiO2 hollow spheres and TiO2 hollow spheres/TiO2 hollow spheres double-layered films are investigated, and their photoelectric conversion efficiencies were determined to 4.52, 7.10 and 5.48%, respectively. Dye-sensitized solar cells based on double layered composite films of TiO2 nanoparticles and TiO2 hollow spheres exhibit the highest photo-electric conversion efficiency mainly due to the combined effect of two factors, the high light scattering of over-layer hollow spheres that enhance harvesting light of the Dye-sensitized solar cells and the under-layer TiO2 nanoparticle layer that ensures good electronic contact between TiO2 film and FTO conducting glass. The double layered composite TiO2 film electrodes are a promising development in enhancing the performance of dye-sensitized solar cells.

The carbon counter electrodes for Dye-sensitized solar cells (DSSCs) were deposited on FTO glass using graphite target by bipolar pulse magnetron sputtering. The effects of sputtering pressure on the structures and properties for carbon films were investigated. The carbon bond structure was analyzed by Raman spectra. The sheet resistance of carbon film was detected by four-probe tester. The transmittance was tested by UV-visible spectrum. The performance of DSSCs was tested by solar simulator after the cells assembled. The results indicated that the ratio of ID/IG reduced, the degree of graphitization decreased, sheet resistance raised, transmittance increased and photoelectric conversion efficiency reduced with the increasing of sputtering pressure.

A multilayer TiO2 film featured with gradual scattering structure was developed and used as photoelectrode for dye-sensitized solar cells. This structure of film consists of P25 nanoparticles and TiO2 aggregate which was synthesized by micro-emulsion method as scattering centers The scattering centers were deposited by gradually increasing the amount from the film’s bottom to its top. The special films were used for the studies on the photovoltaic performance of N719 and Zn-3, and their photoelectric conversion efficiencies were 7.34% and 4.04%, respectively. Furthermore, more improvement of the conversion efficiency is realized for Zn-3 than for N719 by using our newly developed multilayer films as photoelectrode compared with ordinary photoelectrode.
