通过一维（1D）TiO 2纳米管、三维（3D）TiO 2分级微球以及具有大表面积的零维（0 D）纳米颗粒的组合，开发了一种用于染料敏化太阳能电池的具有协同效应的设计和优化的钛金属基底上的三层TiO 2光电极。有效的电荷收集，光捕获，以及高染料负载能力的优点，使其能够实现前所未有的高短路光电流密度（17.90 mA cm-2）的背面照明下，从而使我们能够获得高达9.10%的功率转换效率。
An engineered and optimized trilayered TiO2 photoelectrode on Ti metal substrates with synergistic effects for dye-sensitized solar cells has been developed through the combination of one-dimensional (1D) TiO2 nanotubes, three-dimensional (3D) TiO2 hierarchical microsized spheres, as well as zero-dimensional (0D) nanoparticles with a large surface area. The advantages of efficient charge-collection, light-harvesting, as well as high dye-loading capability make it possible to achieve unprecedentedly high short-circuit photocurrent density (17.90 mA cm–2) under back-side illumination and thus allow us to obtain a power conversion efficiency as high as 9.10%.
