综述了近年来各种硅微纳结构的特征和制备技术, 介绍了其在新型太阳电池中的应用现状与前景.首先, 阐述了硅微纳结构在传统p-n结、新型径向p-n结以及异质结太阳电池结构设计中的研究进展；其次, 从光吸收增强、表面修饰及钝化的角度, 分析了硅微纳结构太阳电池的增效措施；最后, 提出了柔性硅微纳结构太阳电池开发的新思路.

In this perspective, we reviewed the fabrication technologies of various silicon micro-nano structures and their applications in novel type of solar cells. The recent progress in the application of silicon micro-nano structures in traditional p-n junction solar cells, radial p-n junction solar cells and hetero-junction solar cells are discussed respectively. We then shown the recent efforts to improve the energy conversion efficiency of the solar cells with silicon micro-nano structures, including enhanced absorption of incident light, as well as surface modification and surface passivation of silicon micro-nano structures. Finally, brief overview and outlook are provided on the development of flexible silicon solar cells.
