The growth, structural, electrical and optical properties of FTO thin layers are thoroughly investigated within the team. FTO layers with physical properties at the-state-of-the-art can be grown with size larger than 100 cm2. The carrier mobility and crystallographic texture have thoroughly been investigated [1,3]. We also demonstrated that novel hazy ZnO-SnO2:F nanocomposite films can be fabricated via a simple two-step process. In this approach, polycrystalline FTO thin films are grown by atmospheric spray-pyrolysis on previously spin-coated made 3D substrates, featuring randomly distributed ZnO nanoparticle aggregates. By changing the initial spin-coated solution concentration, light scattering efficiency can be readily modulated over a large range of Haze factor. Our nano-composite thin films demonstrate excellent electro-optical properties compatible with energy applications by using low-cost and simple growth methods.
