“…Many studies reported that the use of TiO 2 nanostructure in photoelectrochemical cells improved its performance, due to their large surface area which provides a direct pathway for electrons to transfer. Particle size and shape are two parameters that affect the performance of dye-sensitized solar cell [1]. TiO 2 nanostructures with high photo-activity and good optical property depend on their particle size and shape.…”

“…TiO 2 nanostructures' photoelectrochemical cells with high efficiency can be fabricated by simple method [2]. The mesoporous titania film with dense and compact structure is an important component of the cell in order to obtain high conversion efficiency [1]. To achieve a highly crystalline TiO 2 nanostructure with modified morphology and shape, several techniques can be used: sol-gel, chemical vapour deposition, hydrothermal process and screen printing [3].…”

TiO 2 nanostructures have been treated using different kind of surfactant to modify its optical absorption and morphology. TiO 2 nanostructures were prepared via simple method on indium tin oxide (ITO) surface, namely, liquidphase deposition technique (LPD) at 50°C. The TiO 2 nanostructures film with a thickness of about 236 nm was annealed at 400°C for 1 h in the air to enhance the interconnectivity of the particles. The dense and compact TiO 2 nanoparticle with different shape, particle size and surface morphology was used as a photovoltaic material in a photoelectrochemical cell of ITO/TiO 2 /electrolyte/platinum. TiO 2 nanostructure films were treated with three different kinds of surfactants: cetyltrimethylammonium bromide (CTAB), hexamethylenetetramine (HMT) and polyvinylpyrrolidone (PVP). It was found that the film treated with HMT performed best, with a J sc of 57.5 μA/cm 2 . In conclusion, optical absorption, band gap and grain size of TiO 2 nanostructure influenced the performance of the cell.

“…There is growing recent interest in using various 1-D structures for solar cell applications, including CdSe, dye-sensitized TiO 2 and ZnO nanorods, nanowires, and nanotubes [232][233][234][235][236][237][238][239]. In many cases, improved photovoltaic performance has been found compared to 0-D nanoparticle films.…”

This chapter provides an overview of some recent research activities on the study of optical and dynamic properties of semiconductor nanomaterials. The emphasis is on unique aspects of these properties in nanostructures as compared to bulk materials.Linear, including absorption and luminescence, and nonlinear optical as well as dynamic properties of semiconductor nanoparticles are discussed with focus on their dependence on particle size, shape, and surface characteristics. Both doped and undoped semiconductor nanomaterials are highlighted and contrasted to illustrate the use of doping to effectively alter and probe nanomaterial properties.Some emerging applications of optical nanomaterials are discussed towards the end of the chapter, including solar energy conversion, optical sensing of chemicals and biochemicals, solid state lighting, photocatalysis, and photoelectrochemistry.2

“…Dye-sensitized solar cells (DSSCs) have attracted more and more interests because of their high efficiency and relatively inexpensive fabrication procedure compared with conventional silicon-based solar cells [1][2][3][4]. The electrode of DSSCs usually includes a mesoporous oxide layer (such as TiO 2 , ZnO and SnO 2 ) and a single molecular dye layer.…”
