Abstract

A simple one-pot method to prepare complex morphology-tunable hierarchical TiO₂ microspheres consisting of radially assembled single-crystalline rutile TiO₂ nanorods is developed by combining an acid thermal crystallization process and a self-assembly process of the nanorods via a solvothermal amphiphile-water microreactor strategy. Using P25 nanoparticles as void fillers to generate a mesoporous electrode film, the microsphere based photoanode exhibits a maximum power conversion efficiency of 7.95% at an anode film thickness of 27.2 μm, highlighting the importance of material architecture tailoring in improving the electron transport properties of dye-sensitized solar cells. © 2014 The Royal Society of Chemistry.
