Optics 2023-09-19 v1

Abstract

We designed ordered and disordered silicon (Si) nanowire structures and analyzed their optical performance using the finite-difference time-domain (FDTD) technique. We studied the orderness of nanowire structures by calculating scalar variance. This study reveals that utilizing disorder structures can increase the average absorbance of Si nanowire structures. Spatial electric field distributions provided insights into light-matter interaction, indicating that disorder structures had higher path lengths compared to the periodic structure. We achieved an average absorbance of 41.46% for the hyperuniform Si nanowire structure with a maximum absorbance of 78.18%. Intuitively, we obtained ~70% high absorbance compared to periodic Si nanowire structure. Our findings will be conducive to designing new efficient solar cells and photodetectors.
