摘要：

A high power conversion efficiency of 10.24% can be obtained in a dye-sensitized solar cell by incorporating multiwall carbon nanotubes inside a TiO2 nanorod photoanode. The multiwall carbon nanotubes in the nanorod can effectively collect and transport photogenerated electrons reducing the recombination as well as improving efficiency of the device.
