dye-sensitized solar cell, TiO2, solution combustion synthesis

The nanocrystalline anatase TiO2 films were prepared and characterized in connection with their application to dye-sensitized solar cells. Solution combustion synthesis of TiO2 nanocrystalline film is based on hydrolysis, nitrated, and combustion reaction. The solution combustion synthesis of TiO2 powders was investigated over a wide range of synthesis conditions by using the metal nitrates(oxidizer)-urea(fuel) system. Titanium ( ) n-butoxide was hydrolyzed to obtain titanl hydroxide [TiO(OH)2], and titanyl nitrate [TiO(NO3)2] was obtained by reaction of TiO(OH)2 with nitric acid. Finally, the aqueous solution containing titanyl nitrate [TiO(NO3)2] and a fuel, urea, were mixed and combusted to obtain the well performance TiO2. A high light-to-electricity conversion yield was achieved by applying the titania as a thin film in dye-sensitized solar cells.
