The Window Layer Doping Effect on the Performance of a SiOx:H Based Solar Cells

In this work, the conversion efficiency of hydrogenated amorphous silicon oxide (a-SiO_x:H) based solar cells was analyzed and designed by SCAPS-1D software. So, we have investigated by numerical simulation the influence of the p-nc-SiO_x:H window layer doping concentration (Na) on the performance of the n-i-p single junction solar cell. However, our calculation was carried out by variyng the doping concentration (Na) between 10¹⁸ and 3×10¹⁹ cm^-3. The best results obtained with the Na optimized value are VOC = 989 mV, JSC = 13.9 mA/cm², FF = 77.6 % and a conversion efficiency value equal to 10.67%.
