DYE-SENSITIZED SOLAR CELL USING A TIO2 NANOCRYSTALLINE FILM ELECTRODE PREPARED BY SOLUTION COMBUSTION SYNTHESIS

摘要

This investigation was aimed at preparing well performance TiO2 for dye-sensitized solar cell by solution combustion method. The solution combustion synthesis of TiO2 powders was investigated over a wide range of synthesis conditions by using metal nitrates (oxidizer)-urea and glycine (fuel) system. Titanium ( ) n Ⅳ -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,i.e. urea or glycine was combusted to obtain the TiO2 nanoparticles. The TiO2 nanoparticles thus obtained were used to fabricate electrodes for DSSC. The performance of the DSSC was measured and compared with those fabricated with commercial TiO2 powders.
