Abstract: PURPOSE: A titanium dioxide nanopowder for high efficiency longevity dye-sensitized solar cell and a manufacturing method thereof are provided to increase photoelectric conversion efficiency through vapor synthesis and post-annealing. CONSTITUTION: A titanium dioxide nanopowder for high efficiency longevity dye-sensitized solar cell and a manufacturing method thereof comprises the following steps: forming titanium nanopowder by using titanium alkoxide precursor; and post-annealing the titania nanopowder to form anatase type titanium nanopowder having bipyramid structure. The titanium dioxide precursor is one or more selected from titanium tetraisopropoxide, titanium methoxide, titanium ethoxide, titanium butoxide, titanium tertiary butoxide and titanium ethylhexoxide. The post-annealing is processed at 400-600 deg. Celsius for 0.5-10 hours.
