【 摘 要 】

The effect of calcination temperature on the phase stability of solvothermally synthesized mesoporous anatase TiO2 microspheres has been investigated through X-ray diffraction and Raman spectroscopy. Morphological change owing to anatase to rutile phase transformation has been examined by transmission electron microscopy. Dye-sensitized Solar Cell with anatase TiO2 microspheres photoanode exhibits good photovoltaic performance with an overall cell efficiency of 4.47 %. Calcination above 900 °C reduces the efficiency. Incident Photon to Current Conversion Efficiency (IPCE) studies reveals that the TiO2 microspheres calcined at 700 °C have high IPCE due to high dye loading owing to its high surface area and porous structure.
