|Abstract: ||Aluminium doped zinc oxide (AZO) has attracted significant attention for replacing ITO. In the current work two approaches are presented for the wet-chemical processing of AZO.
Chemical solution deposition of aluminium doped zinc oxide, by spin coating a 2-butoxyethanol precursor, yields TCO coatings with a transparency higher than 90 % and a resistivity of 1.3 mOhm cm after annealing in a reducing atmosphere. Furthermore, the potential of this precursor for large area coatings is demonstrated, by transferring the precursor to a spray coating system.
Next, different synthesis routes for AZO nanoparticles are presented leading to particles with various characteristics. Minor modifications of the synthesis conditions have a profound impact in the particle morphology, the crystallographic position of the aluminium dopant and the generation of free charge carriers. Through an in-depth study of their characteristics, the most promising particles can be selected. Also, their potential as building blocks for transparent conducting coatings is demonstrated, providing a resistivity of 9.4 mOhm cm.
In this work we demonstrate that through in-depth characterization we can correlate the synthesis conditions to the intrinsic properties of the obtained oxide, and come to functional, solution deposited TCO coatings.|
