초록
Nanostructured metal oxides have been widely used in the research fields of photoelectrochemistry,photochemistry and opto-electronics. Dye-sensitized solar cell is a typical example because it is based on nanostructured TiO2. Since the discovery of dye-sensitized solar cell in 1991,it has been considered as a promising photovoltaic solar cell because of low-cost, colorful and semitransparent characteristics. Unlike p-n junction type solar cell, dye-sensitized solar cell is photoelectrochemical type and is usually composed of the dye-adsorbed nanocrystalline metal oxide, the iodide/tri-iodide redox electrolyte and the Pt and/or carbon counter electrode. Among the studied issues to improve efficiency of dye-sensitized solar cell, nanoengineering technologies of metal oxide particle and film have been reviewed in terms of improving optical property, electron transport and electron life time.
