The reflection of bilateral porous silicon with macropores or nanowires is calculated according to analytically derived formulas. The formulas take into account the multiple reflections of light at all angles in each porous layer and monocrystalline substrate. Layers of porous silicon are considered as effective media with Lambertian surfaces. The reflection of bilateral macroporous silicon depends on the volume fraction of the pores of the frontal porous layer. The thickness of the frontal layer of macroporous silicon affects the reflection spectrum of bilateral macroporous silicon when the volume fraction of pores is greater than 0.2. The influence of the thickness of the frontal layer of macroporous silicon on the reflectance spectrum of bilateral macroporous silicon increases as the volume fraction of pores increases. The volume fraction of pores of the back porous layer affects the reflection spectrum of bilateral macroporous silicon at wavelengths of light greater than 1.05 m. The volume fraction of pores of the back layer of macroporous silicon affects the reflection spectrum of bilateral macroporous silicon at wavelengths of light greater than 1.05 m. |
