While many studies have found that the power conversion efficiency of OSCs is improved by inserting metal nanoparticles into the OSCs,little has been reported on the use of size-and shape-controlled metal nanoparticles for fine-tuning the optical properties.Here,we investigate the dependence of silver nanoparticles' size and shape,at various concentrations,on the power conversion efficiency of OSCs[1].Also,we propose a metal-metal core-shell nanocube(NC)as an advanced plasmonic material for highly efficient organic solar cells(OSCs).We covered an Au core with a thin Ag shell as a scattering enhancer to build Au@Ag NCs,showing stronger scattering efficiency than Au nanoparticles(AuNPs)throughout the visible range.Highly efficient plasmonic organic solar cells were fabricated by embedding Au@Ag NCs into an anodic buffer layer,poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS)[2,3].
