文摘

A one-pot solvothermal approach has been developed for the synthesis of single-crystal anatase TiO₂ nanospindles. The introduction of adscititious water in nonaqueous reaction mixture is critical for the spindle formation by allowing for a slow growth rate of TiO₂ to facilitate the shape control of TiO₂ nanospindles. Arising from the prominent light scattering effect, the fabricated dye sensitized solar cells with the TiO₂ nanospindles as light scattering layer show a 27% increment of energy conversion efficiency compared to that of P25 single layer film.
