Abstract：Four kinds of surface nanostructures for the efficient light-trapping technique for silicon-based solar cells are summarized,i.e.the metal nanoparticle,nanowire,nanocone and nanohole.Compared with the other kinds of nanostructures,the nanohole has better structural pro-perty and light trapping ability.The fabrication methods of these nanostructures are introduced in detail,such as the metal film anneal,metal-catalyzed chemical etching,dry etching,deep UV lithography and nanosphere lithography.The improvement of the power conversion efficiency using the surface nanostructures is an important research in the field of solar cells.With its excellent optical and electrical characteristics,the surface nanostructures will have great potential applications in future high efficient photovoltaic devices.
