Abstrakt: In the present work, a thin film solar cell structure consisting of thin GaAs layer, metallic nanoparticle array and aluminum back reflector is proposed and studied to calculate optical absorption and current density using finite difference time domain (FDTD) numerical simulation method. Simulation results show that in comparison to other metallic nanoparticles, aluminum nanoparticles have strong plasmonic scattering effect at optimized period of 100nm and radius 40nm to improve the efficiency of thin film GaAs solar cells through enhancement of current density integrated over solar spectrum by 31% compared to bare thin film GaAs solar cells.
