The invention provides an
iodine-
doping titanium dioxide
microsphere electrode and a manufacturing method thereof. The method is characterized by under a
room temperature, mixing and stirring absolute ethyl
alcohol, lauryl amine and
isopropyl titanate and taking as a precursor solution; and then, using
iodine and deionized water as a reaction solution, dropping and adding the precursor solution in the reaction solution, rapidly stirring and carrying out reaction for 12 hours; and finally, after centrifugal washing, taking a
sediment and adding into the absolute ethyl
alcohol and the deionized water, stirring uniformly, taking a TiO2 reaction
colloid and adding into a reaction kettle, sealing, controlling a temperature in a range of 160-250 DEG C, carrying out reaction for 12hs, and then cooling to the
room temperature, centrifuging, washing and adding ethyecellulose so as to acquire TiO2
slurry, making a TiO2
electrode through
screen printing,
sintering for 0.5h at 500DEG C, and then acquiring the
iodine-
doping titanium dioxide
microsphere electrode. The electrode acquired in the invention possesses a large specific surface area, an effective
electronic transmission path and
high conductivity. And the electrode is used in a quasi-
solid dye-sensitized
solar cell and
photoelectric conversion efficiency of the
cell can reach 6.38%.
