Abstract:

Hierarchical microspheres constructed from a TiO2 core and a SnO2 shell have been successfully fabricated using a one-step solvothermal method. The synthesized products were characterized by XRD, SEM, TEM and FT-IR measurements. It was found that the concentration of precursor Sn4+ in the reaction system plays a key role in the formation of the hierarchical microspheres. The core-shell microspheres of TiO2@SnO2 were formed by a self-assembly process, accompanied by the Kirkendall effect. These core-shell microspheres of TiO2@SnO2 have been used for the first time as the electrode for C106 dye-sensitized solar cells; they exhibited an efficiency of 6.24%. This might be attributed to large surface area and hierarchical structure of the microspheres, leading to light scattering, an increase of dye adsorption, a suppression of charge recombination and prolonging the electron Lifetime.
