| Abstract: | Particle vs tube : The present paper systematically investigates a range of fundamental geometrical and structural features of TiO2 nanotube layers and their effect on the dye‐sensitized solar cell conversion efficiency, to deduce the most promising strategies for improvement. It is found that the performance of the cells strongly depends on the morphology and crystalline structure of the nanotubes.  |
