The wettability of black silicon (BSi) layers fabricated by reactive ion etching (RIE), metal‐assisted chemical (MACE), and laser‐induced (LIE) techniques is studied. contact angles wetting on the samples with deionized water methylammonium iodide‐based perovskite solutions are determined. It found that element composition enlargement area factor BSi have a significant effect their wettability. When tested water, RIE MACE exhibit hydrophobic properties, while LIE layer demonstrates hydrophilic properties due to SiOx‐rich surface structures. also shown aging leads decrease in angle. Upon exposure solution droplets, become highly lyophilic. Based Wenzel Cassie–Baxter models, mechanisms responsible for states identified. In results obtained, valuable insights provided into potential using these tandem perovskite/silicon solar cells.

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.
