The constitutes and mechanism of series resistance of crystal Si modules were analysed, and its value of theoretical calculation was compared with testing value. The results showed that value of theoretical calculation is quite closed to testing value. This paper pointed out that the series resistance of crystal Si modules decreased along with increasing the efficiency of solar cell and improving consistency of I-V curve of solar cell. In this paper, the way for reducing the series resistance of crystal Si modules was forecasted and new module configuration was designed.

The black silicon is fabricated by the metal assited chemical etching method. The rounding effect of the ultra low concentration of NaOH solution on the structure of black silicon is studied, as well as on the performance of the black silicon solar cell. Scanning electron microscope(SEM) and quantum efficiency(QE) tester are used to analyze the structure of black silicon and the performance of black silicon solar cell. The results show that the ultra low concentration of NaOH solution can remove the edges and cusps of black silicon with the widened nanostructure in order to reduce the surface recombination. It is also found that with the NaOH treatment, the nanostructure turns out to be smooth and uniform. The average reflectance of black silicon solar cell is 4.15% in the wavelength range of 400-900 nm. And the average efficiency of black silicon solar cells achieves 17.94%, which is relatively 0.35% higher than that of silicon solar cells fabricated by the traditional acid textured method. © 2015, Editorial Department of Journal of NUAA.

In this paper, large area multi-crystalline silicon (mc-Si) solar cells of 156 mm × 156 mm were fabricated by the combination of Ag-assisted etching and sodium hydroxide (NaOH) treatment. Scanning electron microscope, UV-Vis-NIR spectrophotometer, external quantum efficiency measurement system, and current-voltage test were used to characterize the etched black silicon wafers and the fabricated solar cells. It was found that, though the black mc-Si without NaOH treatment showed a lowest reflectance of 2.03 % in the wavelength of 400-900 nm, the maximum conversion efficiency came from the mc-Si solar cells produced by combination of Ag-assisted etching and NaOH treatment. Though the solar cell with additional NaOH treatment for 30 s presented a reflectance of 5.45 %, it presented the highest conversion efficiency of 18.03 %, which is 0.64 % higher than the traditional mc-Si solar cell (17.39 %) and much higher than that of the black mc-Si solar cell without NaOH treatment (16.24 %). © 2014 Springer-Verlag Berlin Heidelberg.
