摘　　要：太阳电池是新能源领域一个不可忽视的领域。随着纳米技术的不断发展,纳米技术和太阳电池有了越来越多的结合点。综述了纳米结构阵列在太阳电池中的应用,其中包括光子晶体、纳米棒阵列、纳米孔阵列、纳米光栅、屋顶状阵列等纳米结构在太阳电池的活性层、减反层以及电极层中的应用。通过提高光吸收、增大p-n结界面比例、提高载流子传输效率等机理提高太阳电池能量转换效率,揭示了纳米结构在降低太阳电池成本、提高太阳电池能量转换效率方面存在的巨大应用潜力。The solar cell is an important part of the new energy filed.With the fast development of the nano-technologies,there are more and more combinations between nano-technologies and solar cells.The applications of nano-structure arrays in solar cells are reviewed,including the photonic crystal,nano-rod array,nano-hole array,nano-grating and nano-dome array introduced in the active layer,anti-reflection layer and electrode layer.These nano-structures are used to improve the power conversion efficiency of solar cells through increasing the absorption of light,the interface proportion of the p-n junction,the carrie transport efficiency and other mechanisms.This review shows a great potential of nano-structures to reduce the cost and improve the power conversion efficiency of solar cells.
