The external quantum efficiency (EQE) enhancements of > 5% in top cell at wavelengths from 350 nm to 450 nm are achieved as the cell with indium nanoparticles plasmonic structure. Besides increasing in short circuit current (ISC) of 11.20% (from 2.95 mA to 3.28 mA) and in conversion efficiency (η) of 13.5%(from 20.8% to 23.6%) are also obtained under one sun AM1.5G illumination. © 2012 IEEE.current matching; external quantum efficiency; GaAs solar cell; indium nanoparticles; surface plasmonic[SDGs]SDG7Current matching; External quantum efficiency; GaAs solar cells; Indium nanoparticles; Plasmonic; Cadmium sulfide solar cells; Conversion efficiency; Gallium arsenide; Indium; Nanoparticles; Quantum efficiency; Semiconducting gallium; Plasmonsconference paper10.1109/PVSC.2012.6317733
