染料敏化太阳能电池（DSSCs）作为一种极具发展前景的能量转换器件，由于其高效、低成本的特点，在近二十年来受到了广泛的关注。为了获得更高的能量转换效率，采用了不同的TiO2结构来满足大表面积、光散射能力和有效的电子收集的要求。近年来，二氧化钛分层微球（hms）利用其独特的结构，作为一类强大的光阳极材料而出现。本文综述了制备和结构控制TiO2 hms的各种方法。随后，重点说明了hms的结构优势，如高表面积、亚微米尺寸的直径和相互连接的主要构建块，而不是它们在DSSCs中的性能。最后，我们深入讨论了阻碍基于HMS的DSSC在功率转换效率方面取得显著进步的原因。此外，还讨论了hms的进一步优化及其在其他太阳能转换装置中的潜在应用。
Dye-sensitized solar cells (DSSCs), as a type of promising energy conversion device, have received much attention in the past two decades due to their high efficiency and low cost. In order to achieve higher energy conversion efficiency, different TiO2 structures have been employed to fulfill the requirements of large surface area, light scattering capability and effective electron collection. In recent years, TiO2 hierarchical microspheres (HMSs) emerged as a class of robust photoanode materials to integrate the above-mentioned qualities, taking advantage of their unique structures. This review summarises the vast array of methods for the fabrication and structural control of the TiO2 HMSs. Subsequently, it focuses on illustrating the structural advantages of the HMSs, such as high surface area, submicron-sized diameter and interconnected primary building blocks over their performances when used in DSSCs. Finally, in the perspective, we intensively discuss the reasons preventing the HMS based DSSC from making striking improvements in power conversion efficiency. Moreover, the further optimization of the HMSs and their potential applications in other solar energy conversion devices are also discussed.
