<P>The sea urchin TiO<SUB>2</SUB> (SU TiO<SUB>2</SUB>) particles composed of radially aligned rutile TiO<SUB>2</SUB> nanowires are successfully synthesized through the simple solvothermal process. SU TiO<SUB>2</SUB> was incorporated into the TiO<SUB>2</SUB> nanoparticle (NP) network to construct the SU–NP composite film, and applied to the CdS/CdSe/ZnS quantum-dot-sensitized solar cells (QDSSCs). A conversion efficiency of 4.2% was achieved with a short-circuit photocurrent density of 18.2 mA cm<SUP>−2</SUP> and an open-circuit voltage of 531 mV, which corresponds to ∼20% improvement as compared with the values obtained from the reference cell made of the NP film. We attribute this extraordinary result to the light scattering effect and efficient charge collection.</P>
<P>Graphic Abstract</P><P>The sea urchin TiO<SUB>2</SUB> particles composed of radially aligned rutile TiO<SUB>2</SUB> nanowires noticeably improved both light scattering and charge collection efficiency.
