Abstract
Thin film solar cells are a promising candidate to alternate fossil fuels due to their low cost compared to first generation solar cells; however, as the active layer thickness is decreased in such structures, absorption probability would reduce substantially [1]. One of the techniques to overcome this disadvantages is to use nano plasmonic back-gratings to trap light inside the active layer, due to both waveguide and plasmonic modes. While the first lengthens photon path length and the latter creates strong near fields and both increase the absorption probability inside the active layer [2].
