Abstract
Plasmonic elements, such as metallic gratings, in thin solar cells have a strong potential to increase the solar light absorption. Here, we numerically describe devices where multiple elements are combined, to create a more broadband and spatially distributed absorption. For organic solar cells, we introduce both a front and a back metallic grating, and show that both features act independently to create enhancement pathways. For amorphous silicon solar cells we introduce a metallic back grating and a dielectric front structure. By choosing different periods for these separate gratings, coupling to guided modes with plasmonic or photonic character is strongly optimized. Related Research Topics
