以 P25为原料制备乙炔黑掺杂 TiO2纳米粉体浆料,旋涂法制得乙炔黑-TiO2复合多孔薄膜,用染料N719和天然桑葚色素(MBY)敏化薄膜,组装成染料敏化太阳能电池(dye-sensitized solar cells, DSSCs).借助电化学分析仪对电池进行测试表征.结果表明,乙炔黑的掺入降低了多孔薄膜电极的电荷传递电阻,从而加快了光电子的传递速率；两种敏化条件下,当乙炔黑掺杂量分别为0．15％和0．20％(质量分数)时,电池具有最大的光电转换效率,分别为0．30％和0．40％.电极中乙炔黑的含量过多时,过量的乙炔黑对光的竞争吸收作用降低了电池的光电子产率,引起了光电转换效率的下降.

TiO2 nano-powder slurry was prepared by P25,and acetylene black (AB)-doped TiO2 (AB-TiO2 )com-posite porous films were fabricated by spin coating method.The films were sensitized by N7 1 9 and natural mul-berry pigment(MBY)dye-solution,and the dye-sensitized solar cells (DSSCs)were assembled.The DSSCs were tested by electrochemical analyzer.The results showed that AB dopant could improve the transporting rate of photoelectrons,reduce the carrier recombination.The biggest photoelectric conversion efficiency was 0.30%and 0.40% when AB-doped was 0.15% and 0.20wt% respectively.
