英文摘要：

Large area aligned identical silicon nanowires array was prepared on mono-crystalline p-Si（100） wafers via the metal-assisted electroless etching at room temperature, 1.01 × 10^5 Pa. The morphologies and reflection spectra of the samples prepared at different nitric acid silver concentrations were analyzed. In addition, the photovoltaic performance of solar cell silicon based on the nanowires array was investigated. The results show that the optimal concentration of nitric acid silver concentration is 0.02 mol/L. The photoelectric conversion property of solar cells based on the silicon nanowire arrays were better than that of the ordinary texturing solar cell. The photovoltaic performance of silicon nanowires array was also analyzed via the spectral response of different wavelengths.
