研究了TiCl_4处理对纳米结构SrTiO_3薄膜电极及染料敏化太阳能电池的影响。与未处理SrTiO_3电极相比,TiCl_4处理后的电极能够吸附更多的染料。采用时间分辨电流的方法研究了两种电极的陷阱态分布。在0.2mol/L高氯酸四丁基铵(TBAP)和0.5mol/L高氯酸乙酰丙酮溶液中,未处理SrTiO_3电极和TiCl_4处理电极的陷阱态密度分别为2.85×10~(16)和1.83×10~(16) cm-2。光谱电化学表明TiCl_4处理后SrTiO_3电极导带中自由电子密度增加,暗电流减小,电荷复合减小。测量了N3敏化SrTiO_3电极和TiCl_4处理SrTiO_3电极的光电流电压曲线,发现TiCl_4处理SrTiO_3太阳能电池有较高的光电流密度,这与前面的测试结果相吻合...

The influence of the TiCl 4 post-treatment on nanostructured SrTiO 3 films as electrodes in dye sensitized solar cells was investigated and compared to non-treated films. Compared with bare electrode, the TiCl 4 treated electrode presented more dye adsorption. The trap state distribution was investigated by the measurements of time resolved current. The total trap state densities were calculated to be 2.85×10 16 /cm 2 and 1.83 × 10 16 /cm 2 in 0.2 mol/L tetrabutylammonium perchloride (TBAP) and 0.5 mol/L LiClO 4 acetylacetone solution for non...
