A photovoltaic device is provided that includes a periodic array having a unit cell with a first electrode protrusion of a height H, characteristic width W, and period L. An absorber of nominal thickness T has a volume with a first component between the electrode element protrusions and a second component completely covering the electrode protrusions,. H, W, and L for a given T allow carrier collection from the majority of points within the volume and simultaneously to enhance the photon density distribution within the absorber resulting from path length, photonic and plasmonic effects produced by the topology and morphology created by the electrode shapes and the volume distribution between the first and the second components. |
