Fig. 9From: Light Trapping Enhancement in a Thin Film with 2D Conformal Periodic Hexagonal ArraysDependence of absorption on the periodicity and incident angle. a Calculated absorption of a-Si under normal incident light versus varied periodicity and wavelength. The thickness of a-Si is fixed at 160 nm. b Calculated absorption of a-Si versus varied incident angle and wavelength. The thickness of a-Si is 160 nm, and the periodicity is 300 nmBack to article page
