Hierarchical SnO 2 octahedra consisting of SnO 2 nanoparticles (≈30 nm in diameter) can be successfully fabricated by a fast sonochemical process followed by heat treatment (see figure). The dye‐sensitized solar cell based on the photoelectrodes consisting of the bifunctional hierarchical octahedral SnO 2 shows a power conversion efficiency of 6.40 %.
