Abstract

The absorption enhancement of GaAs solar cells with Cu nanoparticles have been studied by finite difference time domain (FDTD) method. The simulation results showed the 37% light absorption enhancement in comparison to bare. Further, it is also observed that the conversion efficiency of about 1.086 can be achieved at optimized radius and the period of the nanoparticles. Hence, the present result optimized the size and the separation between nanoparticles to get maximum conversion efficiency of GaAs solar cells.
