Dye-sensitized solar cells (DSSCs) are fabricated based on hollow anatase TiO2(HA-TiO2) spheres synthesized by a chemically induced self-transformation (CIST) strategy using urea as a base catalyst, whose walls are composed of anatase nanocrystals and exhibit hierarchical porosity. TiO2hollow structured materials not only have low density, high specific surface areas, and hierarchically porous structures, but also exhibit high light-collection efficiency and fast motion of charge carriers. Effects of calcination temperatures on the performance of HA-TiO2solar cells are investigated and discussed. With increasing calcination temperatures, the light–electricity conversion efficiencies (η) increase. At 600°C, HA-TiO2cells reach the highest efficiency. The performances of HA-TiO2cells are also compared with Degussa P-25 (P25) TiO2nanoparticle cells at the same film thickness, and their optimal efficiencies at 600°C are 4.82 and 4.35%, respectively. The enhanced performance of HA-TiO2cells is due to their high surface area and hierarchically nanoporous structures when compared with the nonporous TiO2nanoparticles (P25).
