Far-field scattering plots showing the angles at which 700 nm light is scattered back into the Si from the rear interface of the cell for varying sized hemispherical Ag MNPs coated with 500 nm of MgF₂ as well as a rear mirror. The 300 nm and 400 nm MNPs have an absorption peak in Ag at this wavelength while the other sizes do not.
