ZnxCd1-xSe@ZnO hollow spheres (HS) were successfully fabricated for application in quantum dot sensitized solar cells (QDSSCs) based on ZnO HS through the ion-exchange process. The sizes of could be tuned from ~300 nm to ~800 using pre-synthesized by different carbonaceous as templates. photovoltaic performance QDSSCs, especially short-circuit current density (Jsc), experienced an obvious change when are employed. with average size distribution ~500 presented a better than QDSSCs other HS. When mixture sizes, power conversion efficiency can further improved. effect spheres, light scattering, and composition gradient structure responsible enhancement performance.
