“…Besides electron transporting, the porosity of TiO 2 nanoparticles offers large surface area for dye adsorption. Particularly, this affects the number of dye molecules that can be adsorbed [25][26][27][28]. At a certain level of porosity, TiO 2 particles can adsorb the maximum amount of dye which affects the performance of the DSSC.…”

The application of natural dyes extracted from plant seeds in the fabrication of dye-sensitized solar cells (DSSCs) has been explored. Ten dyes were extracted from different plant seeds and used as sensitizers for DSSCs. The dyes were characterized using UV-Vis spectrophotometry. DSSCs were prepared using TiO 2 and ZnO nanostructured mesoporous films. The highest conversion efficiency of 0.875 % was obtained with an allium cepa (onion) extract-sensitized TiO 2 solar cell. The process of TiO 2 -film sintering was studied and it was found that the sintering procedure significantly affects the response of the cell. The short circuit current of the DSSC was found to be considerably enhanced when the TiO 2 semiconducting layer was sintered gradually.

“…Then, researchers started to survey the use of ordinal TiO2 in dye sensitive solar cells; this includes TiO2 nanowires, nanorods and anodized TiO2 nanotubes (ATNTs) which may be an interesting process to improve electron transport through the film. For the formation of an efficient dye sensitive solar cell, photoanode materials with various morphologies such as nanoparticles [3], ordered mesostructured materials [4], one-dimension structured materials (nanorod, nanowire and nanotube) have been extensively explored [5,6]. It is now well-accepted that a high-efficiency photoelectrode for dye sensitive solar cells requires not only a high surface area for the loading of large amounts of dye molecules but also a tailored microstructure for light harvesting and fast electron transport [7].…”

Anodized TiO2 nanotubes have recently became one of the favourable active anodes in making dye sensitive solar cell. This work investigate the effect of morphological properties of the anodized TiO2 on the electrical conversion efficiency (η %) of the dye sensitive solar cells fabricated using N3 commercial dye, polymers blend (KI/PEO/PMMA) as electrolyte and electro-polymerized polyaniline on fluorinedoped tin oxide glass as counter electrode. Different morphological TiO2 were produced via anodizing of the Ti foil in ethylene glycol containing 0.5 % NH4F and 4 mL deionized water, at different anodizing potentials; namely 10, 20, 30, 40, 50 and 60 v for 1 h at room temperature. The deposited anodized TiO2 nanotubes layers extensively characterized using scanning electron microscope. The calculated (η %) ranged between 0.370 and 2.126 %, the relation between these values and the tubes parameters were discussed.

“…Dye-sensitized solar cell (DSSC) is one of the attractive solar cells and has been widely studied [1][2][3][4][5][6][7][8][9][10]. More recently, some researchers reported that the DSSC shows more than 11% energy conversion efficiency [1,2].…”

“…TiO 2 thin films have been formed on the TCO substrates by spin-coating [3,4], doctor-blading [5,6], sputtering [7,8] and anodizing [9,10] methods. The common process of these methods was post-annealing at ~723 K due to sintering of TiO 2 nanoparticles and crystallization of the deposited films.…”

In this study, mesoporous TiO 2 films were formed on ITO conductive glasses by anodizing of titanium thin films without post-annealing. The titanium thin films, ~200 nm thick, sputter-deposited on to the ITO substrates were anodized at 20 V in a phosphate/glycerol electrolyte at 433 K. A completely transparent TiO 2 specimen was obtained by anodizing for 60 s. The as-anodized mesoporous TiO 2 films consisted of anatase, even without post annealing. The transparent mesoporous TiO 2 film anodized for a suitable time showed much better photoelectrochemical performance than the post-annealed TiO 2 nanotubular film.
