We report an enhanced conversion efficiency of femtosecond-laser treated silicon solar cells by surface modification of anisotropic-etching.The etching improves minority carrier lifetime inside modified black silicon area substantially,givsing rise to a improved carrer recombination properties; moreover,after the etching,an inverted pyramids/upright pyramids mixed texture surface is obtained,which shows better photon capturing capability than that of conventional pyramid texture.
