Abstract
In this work, I proposed a new structure for amorphous solar cell with improved light harvesting and power conversion efficiency using plasmonic nanoparticles distributed inside the solar cell active layer and nanoantennas distributed on the top surface with a metallic grating as back reflectors. Different metals are used as plasmonic nanoparticles such as gold, copper, silver and vanadium dioxide. The optimum shape, size and position of plasmonic materials are determined using a finite difference time domain (FDTD) simulation tool. Nanoantennas height, position, separation distance between them will be also optimized using FDTD method. Improving the light absorption in the wavelength range 600-800 nm is obtained.
