Hierarchically structured aggregates, consisting of TiO nanoparticles were produced via one-step solvothermal syntheses with a mixed solvent system containing both acetic acid and ethanol. Two of the resulting structures, one ~700 nm and the other ~300 nm in diameter, were found to be comprised of 8.5 nm and 10.5 nm anatase crystals, and possess specific surface areas of 138 and 106 m g respectively. These particles were incorporated into Dye-sensitized Solar Cells (DSCs) as high surface area scattering layers, along with a layer of a transparent material. Solar-to-electric conversion efficiencies (PCE) of 9.1% and 8.2% were recorded using these aggregated particles as compared to those of commonly used large particles scattering layer 7.4%.
通过一步溶剂热合成法，使用包含乙酸和乙醇的混合溶剂体系，制备了具有分级结构的 TiO 纳米粒子聚集体。两种产物的结构分别约为 700nm 和 300nm 直径，由 8.5nm 和 10.5nm 的锐钛矿晶体组成，并分别具有 138 和 106m2/g 的比表面积。这些粒子被掺入染料敏化太阳能电池（DSC）中，作为高表面积散射层，并与一层透明材料结合使用。与通常使用的大颗粒散射层 7.4%相比，使用这些聚集颗粒作为散射层的太阳能-电能转换效率（PCE）分别为 9.1%和 8.2%。
