摘要： 研究了三甲川菁敏化SnO₂纳米结构电极的光电化学行为。结果表明，三甲川菁染料电子激发态能级位置能与SnO₂纳米粒子导带边位置相匹配，从而使用该染料敏化可以显著地提高SnO₂纳米结构电极的光电流，使SnO₂纳米结构电极吸收波长红移至可见光区和近红外区，光电转换效率得到明显改善，IPCE值最高可达28.9%。

Abstract: The photoelectrochemical behaviors of the SnO₂ nanostructured porous film sensitized by cyanine dye were investigated in this paper. The results showed that the excitation state level matched the conduction band edge of SnO₂ nanoparticle. Therefore the sensitization of this dye can increase the photocurrent intensity of SnO₂ nanostructured electrode obviously and results in a red-shift of optical absorption from the ultra-violet region to the visible region. As a result, the light-to-electricity conversion efficiency was improved evidently, the maximum value of IPCE has reached 28.9%.
