Investigation Of Variable Sized Silver Nanospheres Deposited On ITO/C-Si Structure As FDTD Simulation Model For Plasmonic Solar Cells

Abstract

The adoption of metal nanoparticles has been well demonstrated for enhanced absorption in solar cells. In this work, effect of size of silver nanospheres (AgNS) deposited upon ITO(indium tin oxide)/crystalline silicon(c-Si) substrate has been investigated using MEEP software via FDTD method. Scattering efficiency enhances from 0.1% (corresponding to 30nm) to15.6% (corresponding to 100nm) in visible region. Maximum response of transmittance at transparent conducting oxide (TCO)/semiconductor interface has been observed for 100nmAgNS.Spatial distribution of electric field intensity shows enhanced near field spectra around the nanospheres as well as in the active layer of structure.
