Metal oxides are the key ingredients for the development of many advanced functional materials and smart devices. Nanostructuring is one of the best ways to exploit their properties. Zinc oxide (ZnO), tin oxide (SnO2), and titan dioxide (TiO2) are materials that have been mostly studied for various nano-applications. Metal oxides can be prepared in various sizes and geometries, but one of the greatest challenges remains the precise control of the particle size, shape, crystalline structure and processing properties. The present contribution presents preliminary results of chemical synthesis and characterization of various nanostructured low work-function metal oxides for potential applications in organic solar cells application as electron extraction interlayer.
