Abstract

The application of double-walled carbon nanotubes on amorphous silicon solar cell to improve light trapping and shift the surface plasmon from periodic nanostructure is proposed. A thin film of double-walled carbon nanotubes is coated on the hexagonal nanostructured silver film and uses as the back reflector of solar cells. Based on the periodic Ag nanostructure, the surface plasmon is constructed; with the addition of double-walled carbon nanotubes on the Ag nanostructure, the surface plasmon is red shifted owing to the changing environment around the surface and the light scattering effect is improved due to this rough surface. Our results suggest that by controlling the DWCNTs density on Ag nanostructure, the performance of the short-circuit current and power conversion efficiency can be enhanced
