With decreasing the CH 4/(CH4+SiH4) fluence ratio from 50% to 30%, the Si/C composition ratio of the Si-rich SixC1-x film increases from 1.99 to 2.78. For the Si-rich Si0.74C0.26 film, the broadband absorption spectrum shows the highest optical absorption coefficient of up to 1.9×105 cm-1. The ITO/p-Si xC1-x/i-SixC1-x/n-Si xC1-x/Al solar cell provides the conversion efficiency and filling factor enhancing from 1.41% to 2% and from 23.1% to 25.6%, respectively, by enlarging the Si/C composition ratio of i-SixC 1-x layer from 1.99 to 2.78. © 2013 IEEE. |
