General description

This nickel oxide nanoparticle ink is a nanoparticle based printing ink allowing processing temperatures of 80-120°C. The nickel oxide nanoparticle ink is a hole selective interface layer ink containing nickel oxide (NiO) nanoparticles in ethanol. The NiO nanoparticle ink functions well as hole extraction layer (HEL) material in solar cells.

Application

This NiO nanoparticle ink is for slot-dye, spin-coating and doctor blading for the use as hole transport layer in printed electronics. The NiO nanoparticle ink is universally applicable in normal and inverted architecture.

Preparation Note

  • Storage: In dark at room temperature.
  • Prior to application: Shake, ultrasonicate with sonic horn (50W, 1min/100mL) or bath (5min/100mL). Optionally filter through 0.45μm PP or PTFE filter.
  • Post-treatment: Annealing of deposited films at 80°C - 120°C.
  • Thickness optimization may be necessary.
