Figure 5From: Design of dual-diameter nanoholes for efficient solar-light harvestingAbsorption spectra. Absorption characteristics of the top/bottom nanoholes in the optimized DNHs. The absorption percentages of the total system, top NH layer, and bottom NH layer are defined here as Ptot, Ptop, and Pbot, respectively. The thin lines are the calculated absorption spectra, and the thick ones are the smoothed versions.Back to article page
