Schematic structure of the simulated plasmonic OPV cell. The symbols, T, D, and P, are active layer thickness, nanosphere diameter, and period, respectively.
For , , and , (a) -polarized incident absorption spectra of the pristine and hybrid active layers using and ; electric field distributions of x-y cross sections cutting through a nanosphere in hybrid active layers at , (b) and (c) for -polarized incidence in and , (d) for -polarized incidence in . In the color bar, and are the electric and magnetic fields of incident light source and is the normalized electric field intensity.
For , 10, 15, and 20 nm and in and , (a) Light concentration factor as a function of nanosphere period P, (b) Light concentration factor as a function of volume ratio of silver in hybrid active layers.
