Reduce Fabry–Pérot interference

  Hello, I found that light interference usually happens in the simulation of finite-thick solar cells, causing oscillation in the reflectance graph. This is especially severe when they are coated with semi-transparent materials and structures.
  How can I reduce the Fabry–Pérot interference?
  The solar cell structure is like below:
  -      Si substrate thickness = 150 μm
  -      The SiNx layer is coated for the front and rear sides.
  -      The MD600 (a kind of polymer material) hyperbola structure is formed for the front and rear sides.
