Synthesis of Zn_xCd_1-xSe@ZnO Hollow Spheres in Different Sizes for Quantum Dots Sensitized Solar Cells Application.

ABSTRACT: Zn_xCd_1-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 the Zn_xCd_1-xSe@ZnO HS could be tuned from ~300 nm to ~800 nm using ZnO HS pre-synthesized by different sizes of carbonaceous spheres as templates. The photovoltaic performance of QDSSCs, especially the short-circuit current density (J_sc), experienced an obvious change when different sizes of Zn_xCd_1-xSe@ZnO HS are employed. The Zn_xCd_1-xSe@ZnO HS with an average size distribution of ~500 nm presented a better performance than the QDSSCs based on other sizes of Zn_xCd_1-xSe@ZnO HS. When us
