Figure 6From: 3D simulation of morphological effect on reflectance of Si3N4 sub-wavelength structures for silicon solar cells3D view for the height effect on the reflectance with respect to different wavelength. (a) The pyramid-shaped Si3N4 SWS has lower reflectance and less sensitivity on structure height in comparison with (b) the cylinder-shaped Si3N4 SWS.Back to article page
