摘要：
A novel ZnO nanorod/nanoparticle (NR/NP) hierarchical structure on a zinc foil has been fabricated through a chemical bath deposition method. When used as a flexible photoanode for DSSCs, such a structure demonstrated enhanced dye-loading and electron lifetime as compared to the NR structure. It also retarded the charge recombination while maintaining the electron diffusion length of the NR structure. As a result, the power conversion efficiency of the DSSCs based on the NR/NP structure increased from 1.35% to 3.63% with a 169% enhancement as compared to that based on ZnO NRs.
