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.
