摘要：
We report a facile way to fabricate three-dimensional (3D) Ni-TiO2 core-shell nanowire arrays through anodic aluminum oxide template-assisted sol-gel TiO2 nanotube shell growth followed by Ni core using room temperature constant current electrodeposition. The 3D Ni-TiO2 nanowire-based dye-sensitized solar cell (DSSC) endows a 67% increase in conversion efficiency as compared with the TiO2 nanotube DSSC and maximum conversion efficiency of 5.07% was obtained by surface treating the photoanode with TiCl4, which provides enhanced light scattering and surface passivation. Indeed, this work paves the way to build reliable 3D Ni-TiO2 nanostructured photoanodes for highly efficient DSSCs.
