摘要：

A new type of TiO2-nano-SiO2 hybrid film was prepared by mixing TiO2 with the nano-sized SiO2 powder. The size of CdSe quantum dots (QDs) was about 2.6nm. The spin-coating method was applied to prepare CdSe QDs sensitized the TiO2-nano-SiO2 hybrid film for the quantum dots sensitized solar cells (QDSSCs) application. It is found that the introduction of SiO2 and the capped ligands show notable influence on the photovoltaic performance. The power conversion efficiency of 1.74% was achieved by using the TiO2-nano-SiO2 hybrid film modified with MPA-capped CdSe (TiO2-nano-SiO2/CdSe(MPA)) under the illumination of one sun (AM1.5, 100mW/cm(2)).
