Abstract Owing to its unique optical properties, light trapping structure plays a more and more important role in the photovoltaic devices. At present, the application of light trapping structure in silicon-based solar cells is quite popular, but its application in GaAs thin film solar cells is little reported. In this article, the principle, research status of light trapping structure and its applications in GaAs thin film solar cells are introduced in detail. Three kinds of light trapping structures for GaAs thin film solar cells are summarized,including light trapping structure on the front surface (such as metal nanoparticle, nanowire, nanocone, etc.),light trapping structure on the back surface (such as back reflection layer), and hybrid light trapping structure. It shows that the application of light trapping structure can further improve photoelectric conversion efficiency of the GaAs thin film solar cells, and can also achieve the goal of reducing the production cost of the solar cells.

Key words： GaAs thin film solar cell light trapping structure on the front surface light trapping structure on the back surface hybrid light trapping structure
