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.

Abstract


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.
