Abstract: In this study, it is proposed to use the method of pulsed cathodic deposition to manufacture anti-reflective, self-cleaning and UV protective nanostructured zinc oxide layers, since this method has additional possibilities for varying the morphology, the structure and the properties of coatings as compared with the commonly used constant-current electrodeposition. The analysis was carried out for optical properties, crystal structure, substructural parameters and the texture of silicon plates electrodeposited in pulsed mode on the surface for nanostructured zinc oxide arrays. The anti-reflective properties of ZnO arrays were demonstrated on Si surface. The development of single-phase ZnO nanostructures with a characteristic texture in <001> direction was determined. The result of the wettability study is a high hydrophobicity of ZnO surfaces which is regulated by the exposure to ultraviolet irradiation. It was shown that such surfaces are self-cleaning ones with the “rose petal effect” and are able to protect Si surface from the destructive action of the solar spectrum ultraviolet part.
