General description

Zinc oxide nanoparticle ink are nanoparticle-based printing inks allowing processing temperatures of 80°C. Zinc oxide nanoparticle ink is an electron selective interface layer ink containing zinc oxide (ZnO) nanoparticles in isopropanol. ZnO nanoparticle ink functions well as electron extraction layer (EEL) materials in solar cells.

Application

This ZnO nanoparticle ink is for slot-dye, spin-coating, and doctor blading for the use as electron transport layer in printed electronics. This ZnO nanoparticle ink is universally applicable in normal and inverted architecture.
Annealing temperature <100°C.

Other Notes

Prior to application: Ultrasonicate and (optionally) filter through 0.45 μm PTFE filter
Post-treatment: Annealing of deposited ZnO films at 80°C - 120°C
