Figure 3.

Chromaticity (top plots) and photocurrent density (bottom plots) for different combinations of pitch and grating height (grating widths fixed at 0.5, checkerboard width at 0.3 and radii at 0.4) for a variety of LT structures: (b) checkerboards (c) crossed gratings, (d) linear gratings, (e) circular nanopillars, (f) domes (latter two in square symmetry layout) and (a) equivalent flat ITO layer. The volume in unit cell increases from domes to pillars, to linear gratings, to crossed gratings, to checkerboards and to flat configuration.
