Degradation mechanisms of the aluminium doped zinc oxide front contact
Figure 6.19
Proposed degradation mechanism for thin film ZnO:Al in the presence of (top) H 2 O and (bottom) H 2 O and CO 2 . In the latter
case, the diffusion of species from the substrate is omitted for clarity. Stain formation is only observed when these reaction
products cannot directly dissolve.
