Transparent conducting oxides

Abstract

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.
