Transparent Conducting Oxides

An introduction to the wet-chemical processing of indium tin oxide (ITO), aluminium-doped zinc oxide (AZO) and antimony-doped tin oxide (ATO) thin films is given, their performance is compared to materials derived from physical and chemical vapour deposition. Strategies to reduce inherent limitations of sol–gel coatings due to residual porosity are emphasized. Printability as a specific advantage of solution-based techniques is highlighted. It also is shown how compositional flexibility and the facile introduction of dopants are used to explore the potential of novel p-type conductive delafossites.
