The planar heterojunction solar cells based on the GaAs films doped with gold nanoparticles(Au NPs)are investigated by a finite-difference time-domain method.The numerical results show that Au NPs effectively increase the light absorption and short-circuit current(Jsc)of GaAs solar cells,when saving GaAs consumption by reducing film thickness.For the GaAs film of 200 nm in thickness,the presence of Au NPs boosts the device Jsc up to 36.94 mA.cm-2,1.29 times that of the counterpart device without Au NPs.In addition,one requires the pure GaAs film of 500-600 nm in thickness in order to get the absorption and Jsc comparable to those from the 200-nm-thick GaAs film doped with Au NPs.It is revealed that the improved Jsc upon doping with Au NPs predominantly originates from the increased absorption of GaAs film as the result of the plasmon resonance effect of Au NPs excited by incident photons.Our results demonstrate that doping photon-harvesting layer with Au NPs is an effective strategy to prepare the solar cells with a strong spectral response and a reduced material consumption.
