Plasmonic Circular Nanostructure for Enhanced Light Absorption in Organic Solar Cells
Figure 3
Normalized reflectance intensity as a function of incident angles for grating pitches = 400, 500, 600, 700, 800 nm and a planar reference sample (Au film without grating). The samples illuminated by a white light source (a) and three visible wavelengths 488 nm (b), 532 nm (c), and 632 nm (d), respectively. The incident light is unpolarized.
