We calculate a maximum absorption of 89.8% for TM-polarized normally incident light in a 5-nm thin-film absorber with a single-pass absorption of only 1.Author/s retain copyrightKeywords: Absorption enhancement; Grating; Near-field; Near-field enhancement; Photovoltaic; plasmonic; Plasmonic resonances; Wide-angle absorption; Polarization; Solar cells; Plasmons Grating; near-field; photovoltaic; plasmonic; solar cellPlasmonic near-field enhancement for planar ultra-thin photovoltaics201310.1109/JPHOT.2013.22805182016-02-24
