• Abstract:

  Optoelectronic devices rely heavily on transparent conducting electrodes (TCE) made of indium oxide (ITO). However, indium scarcity, lack of flexibility, and high costs have driven the search for nanostructured materials, such as silver nanowires (AgNWs), which offer optical and electrical properties comparable to ITO. This research develops a TCE using AgNW and titanium oxide (TiO2) nanocrystals, nanomaterials synthesized by the Polyol and Sol-Gel methods respectively, deposited on glass by centrifugation. The de- position of the thin layer of TiO2 nanocrystals on the AgNWs improves the adhesion of these nanostructures to the glass. Furthermore, it provides excellent thermal and chemical stability, prolonging the useful life of the electrode. The nanomaterials were characterized by UV-vis spectroscopy,  electron microscopy,  and the four-point probe method,  ensur- ing their morphological, optical, and electrical properties, essential to obtain an excellent optoelectronic device.
