Analysis of nanoparticles shape for efficient absorption in nanoplasmonic solar cells

Abstract

The effect of different shapes and grid skew angle of silver nanoparticles on the absorption of nanoplasmonic solar cell is studied using the finite-difference time-domain (FDTD). An FDTD algorithm is used to study the absorption rate of the solar cells with cuboid and cylindrical silver nanoparticles. Moreover, solar cells with axial and skewed grid of silver nanoparticles are considered. The results show that the shape of the nanoparticles affects the absorption rate of the solar cell dramatically, while the skew angle of the grid has a negligible effect.
