In this paper, we have analyzed the antireflection, diffraction order, distribution of light field energy density and the photoelectric conversion efficiency of thin film solar cell with the silicon square nanoconical hole (SiSNH) decorated on its surface under different polarization modes and different top diameters (Drop). The results show that when the incident azimuthal angle (phi) of the transverse electric (TE) polarization takes the Value of 30, an ultimate efficiency of thin film solar cells with optimized SiSNH array is up to 42.83%, which is 3.09 times of the 2.33 mu m thick film solar cell. The results also show that the enhanced ultimate efficiency of the thin film solar cell with SiSNH array is insensitive to Drop and incident light zenith (9) angle. (C) 2017 Elsevier GmbH.
