Paper Title:
Synthesis of TiO2 Nanopowders and their Applications in Dye-Sensitized Solar Cell
  Abstract

Dye-sensitized solar cells (DSSC) are currently attracting widespread interest for the conversion of sunlight into electricity because of their low cost and high efficiency. In these cells, photo-anode is one of the key components for high power conversion efficiencies. In this paper, TiO2 nanopowders were prepared by the non-hydrolytic sol-gel method using TiCl4 as precursor, absolute ethanol and isopropanol as oxygen donor. Several different TiO2 nanopowders were used to fabricate TiO2 solar cells, and properties of TiO2 solar cells were characterized. The solar cell prepared with grainsize 50~80nm TiO2 nanopowders generated a short-circuit photocurrent of 13.17 mA/cm2, an open-circuit photovoltage of 789 mV, a fill factor of 69.8% and the efficiency of 7.25% under the light intensity of 100 mW/cm2.
