Plasmonic Circular Nanostructure for Enhanced Light Absorption in Organic Solar Cells
Figure 2
Measured reflected intensity images with various incident angles (ranging from 10° to 40°) by CCD through TM-polarized, TE-polarized, and unpolarized incident light at three visible wavelengths of 488 nm, 532 nm, and 632 nm, respectively. The grating pitch size is 800 nm.
