Synthesis and Application of ZnO Nanorods Using the Ultra-Thin Porous AAO Template Fabricated by New Method

Electron transport in DSSCs with the TiO2 nanoparticles photoanode become more difficult by the tremendous grain boundaries and disordered pore structures. So, one-dimensional nanostructures have great attractions due to the increased carrier diffusion length by a structural property such as direct pathways for electron transport. In this study, we investigated DSSCs using ZnO nanorod arrays and ZnO nanoparticle/nanorod composite layer as a photoanode. To prevent aggregation of ZnO nanorods, ZnO nanorods were synthesized on the nano-patterned seed dots using ultra-thin porous AAO template fabricated by new method. We confirmed that ZnO naonrods were sparsely grown as the nano-patterned seed dots were used.
