摘　　要：金属纳米颗粒独特的光学性质,使其在薄膜太阳电池新型陷光结构应用方面极具前景。系统地介绍了金属纳米颗粒表面等离激元促进薄膜太阳电池光吸收机理,即光散射增强机理和局域场增强效应。在此基础上,概述了当前金属纳米颗粒陷光结构的制备方法,包括溅射法、电子束刻蚀法、液相还原法、溶胶-凝胶法及反胶束法等。结合国内外最新研究进展深入探讨了典型金属纳米颗粒的尺寸、形状及介电环境等参数对其光学性能和薄膜太阳电池光电转换效率的影响。最后,对金属纳米颗粒增强薄膜太阳电池光吸收的发展前景进行了展望。Metal nanoparticles are expected to have a promising prospect in the application of the new type of the light trapping structure in thin film solar cells due to their unique optical proper- ties. The light absorption mechanisms of solar cells enhanced by the metal nanoparticle surface plasmon are systematically presented, including the light scattering enhancement mechanism and local field enhancement effect. On this basis, the current preparation methods of the light trap- ping structure of the metal nanoparticles are elaborated, such as the sputtering deposition, elec- tron-beam etching method, liquid phase reducing method, sol-gel method and reverse micelles, etc. Based on the latest development status both at home and abroad, the influences of the typical metal nanoparticle structure such as the size, shape, dielectric environment and other parameters on their optical properties and the photoelectric conversion efficiency of the thin-film solar cell were discussed in further. Finally, the development prospect of the light absorption in thin film solar cells enhanced by metal nanoparticles is analyzed.
