This study investigates the optical properties (light reflectance, absorptance, transmittance, and scattering) of black silicon (b‐Si) layers formed using reactive ion etching method. The corresponding spectra are determined across visible, near‐infrared, near‐ultraviolet wavelength ranges (250–1400 nm). It is demonstrated that b‐Si reduce increase absorptance light scattering due to disordered distribution nanoneedles. Increasing duration strengthens this trend. shown etched for 10 min can be considered perfect scatterers upon reflection at wavelengths less than 700 nm. Based on obtained results, possible profits from interlayer perovskite/Si tandem solar cells analyzed. substantiated useful not only within bottom Si subcell but also in top perovskite subcell. prospects future research directions challenges provided.

The optical properties of a tandem three-layered structure crystalline silicon-black silicon-perovskite have been theoretically studied for using it in solar energy conversion. transfer matrix method is used obtaining the analytical expressions reflection, transmission, and absorption coefficients. It shown that can be successfully applied to more complicated case three layers with complex refractive indexes. Numerical calculations performed at an angle incidence radiation 60o showed region short wavelengths reflection coefficient takes on low values (several percent), which gradually increase become > 10% at above 0.8 μm. modeled results are good agreement experimental data carried out structures silicon-TiO2-perovskite. discrepancy between model slowly increases increasing wavelength. transmittance was extremely increased found cheaper easier created may potential
