| 摘 要： | 利用简便的溶剂热法,制得了由锐钛矿相的纳米片组成的、{001}面接近100%暴露的TiO2分级球形结构。利用电泳沉积法,将所得的TiO2分级球形结构作为散射层引入到染料敏化太阳电池(DSSC)中,并很好地保护了这种脆弱的分级结构。由于这种分级球形结构比TiO2纳米颗粒具有更好的染料吸附性能和光散射性能,使用这种TiO2分级球形结构作为散射层的DSSC达到了7.38%的光电转换效率,较之基于TiO2纳米颗粒的DSSC有了26%的提高。

| Abstract: | Anatase TiO2 nanosheet-based hierarchical spheres (HSs) with nearly 100% exposed {001} facets were synthesized via a facile solvothermal process. Using these hierarchical spheres as a scattering layer on nanocrystaline TiO2 film, bi-layered dye-sensitized solar cells (DSSCs) have been fabricated by electrophoresis deposition method, which well preserved the fragile hierarchical structure. Owing to the superior dye adsorption and light scattering effect of HSs, an overall energy conversion efficiency of 7.38% is achieved, which is 26% higher than that of nanoparticle-based photoanode. |
