Application
Al-doped ZnO nanoparticle ink is for spin coating and doctor blading for the use as electron transport layer in printed electronics. Al-doped ZnO nanoparticle ink is universally applicable in normal and inverted architecture with performance comparable to evaporated calcium.

Preparation Note

• Storage: In dark at room temperature.
• Prior to application: Shake, ultrasonicate with sonic horn and (optionally) filter through 0.45μm PTFE filter.
• Post-treatment: Annealing of deposited Al doped ZnO films at 80°C – 120°C.
