Nanoimprint lithography for light trapping applications in solar cells
… current enhancement for cells with a back reflector is 34% and 30% with a multi-disperse array and the mono{u00AD}dispersed array respectively, compared to 13% enhancement due to the reflector alone. The better performance of multi-disperse Ag nanoparticle arrays is attributed to a …
