将直径为500 nm、壳层厚度为25 nm的纳米TiO 2空心球嵌入到P25 TiO 2纳米晶光阳极中，以提高光阳极的光散射能力。制备了不同TiO 2空心球含量的光阳极，并对其形貌进行了系统表征。结果表明，TiO 2空心球对光阳极的形貌有一定的修饰作用。随着TiO 2空心球含量的增加，改性光阳极的光散射能力得到有效提高，染料吸附能力降低。通过优化TiO 2纳米晶中TiO 2空心球的含量，获得了比纯TiO 2纳米晶DSSC（Jsc = 13.96mAcm −2，Voc = 0.686V，FF= 0.684，η= 6.67%，在98.3mWcm−2，AM 1.5下测量）更高的DSSC性能（Jsc = 16 mAcm − 2，Voc=0.72V，FF= 0.648，η=7.59%）。性能的提高主要是由于TiO 2空心球增强了光散射。空心球修饰DSSC的开路电压高于纯P25光阳极DSSC，这是由于空心球取代了TiO 2纳米晶，降低了光阳极表面电荷陷阱密度，减少了界面复合。
The anatase TiO2hollow spheres with diameter of 500nm and shell thickness of 25nm are embedded in P25 TiO2nanocrystalline photoanodes to improve the light scattering ability of the photoanode. Photoanodes embedded with different contents of TiO2hollow spheres are prepared and the profiles of the photoanodes are systematically characterized. It is found that the morphologies of the photoanodes were modified by the TiO2hollow spheres. With increasing the TiO2hollow spheres’ contents, the light scattering ability of the modified photoanodes is effectively improved, while the dye adsorption decreases. By optimizing the TiO2hollow spheres’ content in TiO2nanocrystalline, a higher performance of the DSSC (Jsc=16mAcm−2, Voc=0.72V, FF=0.648 and η=7.59%) is obtained compared with the pure TiO2nanocrystalline DSSC (Jsc=13.96mAcm−2, Voc=0.686V, FF=0.684 and η=6.67%, measured at 98.3mWcm−2, AM1.5). The improved performance is mainly due to the enhanced light scattering by the TiO2hollow spheres. The open circuit voltage of the hollow spheres modified DSSCs is higher than that of the DSSC with pure P25 photoanode, which can be attributed to the fact that TiO2hollow spheres substitute of the TiO2nanocrystallines and reduce the interface recombination by decreasing the surface charge trap-site density of the photoanodes.
