Viscosity: 6.1 ~ 10.1cP

form

dispersion

concentration

2.5 wt. %

work function

-5.3--5.7 eV

particle size

11-21 nm

Application

The WO3-x nanoparticle ink is for inkjet printing for the use as hole transport layer in printed electronics. The WO3-x nanoparticle ink is universally applicable in normal and inverted architecture solar cells.

Preparation Note

  • Storage: In dark at room temperature, Keep in plastic container (glass container can influence dispersion stability).
  • Prior to application: Shake, ultrasonicate with sonic horn.
  • Post-treatment: Annealing of deposited WO3 films at >120°C.
Upon need of ink dilution for viscosity/concentration tunability, 2-propanol can be used as a diluting solvent.
