Enhancement in absorption of amorphous Si solar cell by using conducting anti-reflection coating and plasmonic nano-structured back reflector (1611.07227v1)
Published 22 Nov 2016 in cond-mat.mes-hall
Abstract: In this work is comprising of simulation results of amorphous Si (a-Si) solar cell, in which ITO was used as an anti-reflection coating (ARC). The thickness of ITO was optimized (65 nm) to achieve better performance for spectral region of 350-800 nm. The reflectivity of the solar cell using ITO and SiNx as an ARC were compared. The result is found similar. Further to enhance the light absorption in a-Si, silver nano hemispherical back reflector was used. And it was found that the average absorption by the a-Si has been improved to ~80% by using ITO and hemi spherical nano structured back reflector.
