Solar Cells: One‐Dimensional Hierarchical Nanostructures of TiO₂ Nanosheets on SnO₂ Nanotubes for High Efficiency Solid‐State Dye‐Sensitized Solar Cells (Adv. Mater. 35/2013)

Jong Hak Kim and co-workers report on page 4893 a unique, effective design structure for a photoanode, consisting of an SnO2 nanotube-TiO2 nanosheet core-shell (SNT@TNS), interdispersed in an organized mesoporous TiO2 film. The high efficiency results from the effects of combining the well-organized structure of the TiO2 film and the excellent electron transport, as well as the good light scattering of SNT@TNS.
