英文摘要	Metallic back structures with one-dimensional periodic nanoridges attached to a thin-film amorphous si (a-si) solar cell are numerically studied. at the interfaces between a-si and metal materials, the excitation of surface-plasmon polaritons leads to obvious absorption enhancements in a wide near-ir range for different ridge shapes and periods. the highest enhancement factor of the cell external quantum efficiency is estimated to be 3.32. the optimized structure can achieve an increase of 17.12% in the cell efficiency.
