Abstract
Single-phase anatase nanocrystalline HyCOM-TiO2, (Hydrothermal Crystallizat ion in Organic Media) to label this method was synthesized by high-temperat ure hydrolysis of titanium tetrabutoxide in toluene. The resulting HyCOM-Ti O2, nanocrystalites were found to be covered by n-butoxide, yielding mesopo rous, transparent anatase films with a narrow pore size distribution and go od electron transport characteristic when sintered at 350-550 degrees C on optically transparent conducting glass. Dye-sensitized solar cells made of the Ru-dye-adsorbed mesoporous HyCOM films as photoanodes achieved better p hoto-energy conversion efficiency as compared to those prepared using comme rcially available Degussa P25 films.
