Design and Investigation of Dual Grating Periodic Structure Thin-Film Solar Cell

Article Preview

Abstract:

The studied results found it can not only reduce the thickness of the solar cell but also improve the light absorbed efficiency by using grating as light trapping structure. In this paper, a dual grating periodic structure is designed to improve light absorption efficiency over the spectrum range 330-1400 nm. Then the relationship between groove-depth of dual grating and absorption efficiency is investigated by using finite difference time domain method (FDTD) combining with periodic boundary conditions (PBC).
