avamox for QD-EL

We have developed highly efficient solution processable inorganic charge transport formulations for electroluminescent quantum dot displays (QD-EL displays). Our formulations yield in very thin and stable metal oxide layers with either hole transport (HTL) or electron transport (ETL) function.

Advantages of Avantama ETL and HTL materials
Enabling high-volume mass production of Perovskite PV

Compared to other materials in the market, Avantama avamox materials have the following advantages for the use as ETL and HTL materials:

• Solution processable
  → For e.g. roll-to-roll high-volume Perovskite PV manufacturing
• Low-temperature processing (< 80°C)
  → For temperature-sensitive substrates and fast deposition/drying times
• Coatable on various substrates
• High ink production reproducibility
• High ink shelf life (12+ months)
  → Key for mass production of Perovskite PV
• Nanoparticle and ink production capacity equivalent to 0.2 – 2 GW Perovskite PV/year
• Customer-specific ink customization available
