<br/><br/> Thin film solar cells reduce the cost of solar cells but also reduce the efficiency as light escapes before absorption. To compensate for efficiency reduction, nano - plasmonic surface gratings are used to enhance photons absorption right at solar cell surface. Here we use rigorous coupled wave analysis and scattering matrix methods to study the dependence of generated current on the grating material and profile. Current enhancements can exceed 40% in amorphous silicon thin solar cells through good engineering of plasmonic gratings
