A method for forming a nanostructured titanium dioxide layer by oxidation of a two-layer Al|Ti coating by electrochemical anodizing is proposed and implemented. A special feature of the layer is the preservation of conductive (percolation) properties during fractalization of the structure. The synergistic effect of the combination of the fractal structure of the transport layer, which prevents the degradation of the working layer of the solar cell, and the appearance of percolation conducting channels at the interface of the resulting oxide phases of titanium and aluminum, is promising for the development of interlayer design. Atomic force microscopy techniques have been applied to analyze the nanoarchitectonics of the layers. Keywords: nanoarchitectonics, electrochemical oxidation, Al-Ti, interface, atomic force microscopy.
