Rear located hemispherical silver nanoparticles for light trapping in thin film solar cells

摘要

In this work, we investigate the scattering and coupling efficiencies of the rear located hemispherical silver nanoparticles by using finite difference time domain simulations. The results indicate that the placement and diameters of silver nanoparticles have a strong impact on scattering efficiency. This finding could lead to improved light trapping within a thin silicon solar cell device.
