Zinc Oxide (ZnO) - based transparent conductive oxide (TCO) thin films have attracted much attention to be an alternative choice instead of currently used Indium-tin-oxide (ITO) thin films in transparent electrode applications. However, it is not clear yet which dopant has the best performance on the ZnO-based transparent conductive thin films, and also there are limits on the development and practical applications. This project is focused on development of low cost transparent conductive thin film, from the economical and conductivity concern, the dopants Galium (Ga) and Aluminium (Al) were chosen in the experiments for comparison. The optimizations on these parameters: (1) no doping and doping concentration from 1.0 mole% to 2.0 mole% of ZnO solution; (2) spin-coating speed of the solution; (3) numbers of coating layers; (4) annealing temperature were carried out for achieving the best performance.
