摘要
Double-layered TiO2 photoanodes consisting of bottom nanoparticles and top nanorods are synthesized for dye-sensitized solar cells (DSSCs). The cell performances can be maximized by optimizing the thickness of TiO2 nanoparticle layer, and the preliminary results demonstrate that a promising power conversion efficiency of 8.66% is determined on the device with 10 mu m-TiO2 nanoparticles/nanorods anode, yielding an 30.2% enhancement in cell efficiency in comparison to pristine TiO2 nanoparticle based solar cell.
