Title: Obtaining, properties and application of nanoscale films of anodic titanium dioxide on Ti-Al films for perovskite solar cells
Keywords: anodic titanium dioxide; lead-free paste; nanoscale films; perovskite solar cells; semiconducting properties

Abstract: The modes of synthesis of TiO2 films with semiconducting properties by the method of electrochemical oxidation of Ti are proposed for use as an electronic transport layer of perovskite solar cells. To anodize the titanium film, the electrolyte based on a mixture of a 2% aqueous solution of oxalic acid and a 1% aqueous solution of sulfamic acids was used. The results obtained showed that Al and Ni have injection contacts to the anodic TiO2 films. Nanoscale titanium oxide films have low resistivity and rectilinear and symmetric I - V characteristic branches. Annealing of titanium oxide films leads to a significant decrease in the resistivity.
