Abstract
Embodiment methods and structures include a resonant plasmonic nanostructure located within a thin-film solar cell. This plasmonic nanostructure may trap light and thereby improve the efficiency and light absorption of the cell without increasing physical thickness. In various embodiments, the plasmonic nanostructure may be located within a p-type semiconductor layer of the solar cell. In further embodiments, the index of refraction may vary within the p-type semiconductor layer.
