ABSTRACT
CdS and CdSe quantum-dots-sensitized solar cells (QDSSC) consisted of highly ordered, vertically oriented TiO2 nanotubes were reported. TiO2 nanotubes served both as a large-area support for quantum dots and high-efficiency electron-transporting medium. Anodization method was investigated to fabricate nanotubes directly growing on Ti foil with various anodization time. Under illumination of one sun, the as-obtained QDSSC provided a power conversion efficiency of 1.61%.
