A plasmonic light-trapping concept based on plasmon induced light scattering at nanostructured Ag back contacts of thin-film silicon solar cells is presented. The electromagnetic interaction between incident light and localized surface plasmon polariton resonances in nanostructured Ag back contacts was simulated with JCMsuite.
