In this work, we design via numerical simulation the absorption properties of silicon nanohole arrays of vertically aligned square lattice arrays with lattice constants varying from 300 nm to 400 nm, using the finite difference time-domain method (FDTD). The silicon (Si) is chosen as prototype material for this study due to better understanding of the material properties and widely available optical data. The parameters for photonic crystals are optimized through computer simulations to obtain the maximum absorption and path length enhancement. We investigated the performance of the considered structure and determined the geometrical parameters that allow a better absorption.
