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 TiCl4 post-treatment on nanostructured SrTiO3 films as electrodes in dye sensitized solar cells was investigated and compared to non-treated films. Compared with bare electrode, the TiCl4 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 2.85×1016 /cm2 and 1.83 × 1016/cm2 in 0.2 mol/L tetrabutylammonium perchloride (TBAP) and 0.5 mol/L LiClO4 acetylacetone solution for non-treated ...
