摘要

The performance of solar cells heavily depends on their ability to trap and harvest the Sun’s energy. With the advent of nanotechnology, sub-wavelength nanostructures have been shown to significantly improve the light trapping properties of commercially available Si solar cells. In this work, we explore how nanostructured gratings, of different shapes, enhances light absorption in Si solar cells. Rectangular nanowires, parabolic, triangular, and flat-topped nanocones have been considered. Finite-difference time-domain (FDTD) simulations show that, for the parabolic nano-gratings, more than 80% absorption enhancement is obtained with respect to planar Si solar cells. The simulation results could provide useful insights into the design, optimization, and fabrication of nanostructured Si solar cells with high efficiency.
