Efficiency enhancement of an ultra-thin film silicon solar cell using conical-shaped nanoparticles: similar to superposition (top, middle, and bottom)

摘要: The use of conical-shaped plasmonic nanostructures for light management in an ultra-thin silicon solar cell has been investigated. optical absorption and hence photocurrent are obtained several cases structures using finite difference time domain simulations. In this paper, we demonstrate that the superposition theorem causes significant enhancement due to surface effects nanoparticles. For this, at first, used one nanoparticle top side, then rear finally, three nanoparticles top, bottom, middle sides. Depending on incident wavelength, each manipulates part spectrum. photocurrents 9.165, 10.463, 16.402, 17.761, 18.072 mA/cm2, a without nanoparticles, with NP two NPs bottom middle, respectively. Finally, electrical field distribution generation rate calculated proposed structures.
