Novel multi-shell hollow SiO2@[email protected]2 (HSAT) nanospheres are synthesized by multi-step method. Composite photoanodes and Dye-sensitized solar cells (DSSCs) with different amount of HSAT nanospheres are studied. The study indicates that the HSAT nanospheres have enhanced the scattering and absorption of incident light in the photoanode, reduced the interface transmission resistance, increased the electron lifetime, and thus significantly improved performance of DSSCs. The maximal Jsc and photoelectric conversion efficiency (PCE) obtai...
