Abstract

Plasmonic gallium arsenide (GaAs) solar cells with different metallic nanoparticles are investigated by a three-dimensional device simulation considering both optical and carrier transport response. The external quantum efficiency and metallic absorption are used for a detailed performance comparison for the devices with different metals. Results show that aluminum is beneficial for photovoltaic application due to its extremely low parasitic absorption and strongenough scattering. The effect of the nanoparticle refractive index on the device performance is further examined in order to find the design guideline for efficient light-trapping. It is found that among the popular plasmonic metals aluminum best suits the optimal design.
