Disordered antireflective Huygens metasurface made from High-Index Disks for heterojunction solar cells

With the target to improve the efficiency of solar cells, a disordered arrangement of high-index dielectric submicron-sized disks is experimentally exploited as an antireflective Huygens' metasurface. The response of the entire metasurface is simulated using Born's approximation, where the distribution of the disks obtained from SEM images determines the structure factor while FEM simulations with JCMsuite are used to determine the form factor of the individual disks.
