Application

WO3 nanoparticle ink can be applied in OPV cells as hole extraction layer (HEL) materials. Tungsten oxide nanoparticle ink can be mixed with PEDOT:PSS formulations in order to fine tune electronic and morphological dry layer properties (e.g. conductivity, surface roughness or layer porosity).

General description

This WO3-x nanoparticle ink is for slot-dye, spin-coating and doctor blading for the use as hole transport layer in printed electronics. Tungsten oxide nanoparticle ink is a hole-selective interface layer ink based on a colloidal suspension of tungsten oxide (WO3) nanoparticles in isopropanol. The average size of WO3 particle is optimized around 12-16 nm. Tungsten oxide nanoparticle exhibits high work function, processability and easy layer formation on hydrophilic as well as hydrophobic substrates.This WO3-x nanoparticle ink is universally applicable in normal and inverted architecture solar cells.
Annealing temperature <100°C.
