Plasmonic Nanostructure for Enhanced Light Absorption in Ultrathin Silicon Solar Cells
Figure 2
(a) Absorption spectrum of the bared Si film. The insets show the normalized stimulated magnetic field distributions () at wavelengths of 420 nm and 600 nm, respectively. (b) Absorption spectrum for the proposed solar cell structure under TM polarized plane wave incidences. The absorption enhancement spectrum () is shown in the insets.
