Growth of N-F co-doped titania nanoparticle and applied on dye-sensitized solar cell

Using liquid phase deposition (LPD) fluorine nitrogen altogether doping porous titanium dioxide nanoparticle, general has not doped the titanium dioxide to be able the step to be 3~3.2eV, is opposite to the absorption spectrum for ultraviolet ray 380nm about, but sunlight energy only then 6% in ultraviolet ray, but the visible light has occupied about 52% energy, because grows the titanium dioxide which comes out mainly is applies in the light catalyst and the solar cell, all hoped may enhance to the luminous energy absorption, therefore only then dopes the fluorine, the nitrogen in the titanium dioxide, the goal is in order to adjust the titanium dioxide the light to absorb the boundary (optical absorption edge), at present dopes the method can dope the impurity only then minority produces the key with the titanium dioxide to binding thus result not well, penetrates ammonium hexafluorotitanate and the boric acid by the liquid phase sedimentation mixes under 40 degrees grows ammonium oxofluorotitanate discoid crystal, in the middle of this forerunner fills the very many fluorine nitrogen, after annealing and then produces the titanium dioxide to penetrate the fluorine nitrogen which the ESCA analysis contains compared to, again applies in the solar cell when can observe the annealing temperature differently when remains the fluorine nitrogen which and the key ties to the solar cell efficiency. At present the titanium dioxide light absorbs the boundary to be possible to reach the blue light region, applies the porous titanium dioxide in the dye sensitization solar cell anode, present fill factor may reach about 29.6%.
