染料敏化太阳能电池中TiO2纳米簇光阳极材料制备及其性能研究

he hydrothermal method was applied in the synthesis of TiO2 cluster. The ideal condition was confirmed with the dosage of TiCl4, reaction time and reaction temperature tuned. The cluster turned to be rutile TiO2 with (110) face mainly exposed in raised fiber with the analysis of X-ray diffraction and transmission electron microscope.The conversion efficiency with the mixture of TiO2 cluster and P25 particle as photoanode materials reached 7.28 %. It proved that thelonger electron recombination time and the faster electron transport time was the main reason of high efficiency measured by the intensity-modulated photovoltage spectroscopy and the intensity-modulated photocurrent spectroscopy.
