Polyoxometalate-TiO(2) composites have been successfully introduced into the photoanode of dye-sensitized solar cells to reduce the recombination of the electrons, which results in a longer electron lifetime. The performance of the cells with the polyoxometalate-modified photoanode is better than the cell with a pure P25 photoanode. The effect of the polyoxometalate was studied by electrochemical impedance spectroscopy and open-circuit voltage decay measurement. The results show that the electron lifetime becomes longer following an increase in the amount of the polyoxometalate.
多金属氧酸盐-二氧化钛复合材料已成功引入染料敏化太阳能电池的光阳极中,以减少电子的复合,从而延长电子寿命。与使用纯 P25 光阳极的电池相比,具有多金属氧酸盐修饰光阳极的电池性能更好。通过电化学阻抗谱和开路电压衰减测量研究了多金属氧酸盐的作用。结果表明,随着多金属氧酸盐用量的增加,电子寿命变长。
