General description

  • Helios′Ink H-DZ01015 semi conductive ink developed for the printed electronics is particularly well suited for OPV and PV.
  • This ink shows great performance on Drop On Demand (DOD) inkjet printers.
  • The use of Helios′Ink H-DZ01015 semiconductive ink is greatly improving the devices performances by reducing the roughness of the TCE without a negative impact on the electrical conductivity and the transparency. Life time of the devices is also increased.
  • The use of Helios′Ink H-DZ01015 provides ETL layer with high performances. In addition, compared to standard ETL, the PCE not retained even with higher thickness.

Features and Benefits

Product benefits:
  • Easy deposition under atmospheric conditions (temperature and pressure).
  • Good optical performances (visible light transmission >90%).
  • Non CMR ink.
  • Compatible with ITO layer and Ag NWs layer.
  • Compatible with most flexible substrates.
  • Low drying temperature making printing onto flexible substrates possible.

Preparation Note

Typical processing guideline:
  • Can be homogenized for 5 minutes in an ultrasonic bath in order to get rid of any aggregates.
  • Filtration on a 0.45 μm PTFE filter syringe to avoid any nozzles clogging.
  • Drying conditions: Oven, IR oven, vacuum oven.
  • Clean-up solution: Ethanol/Acetone.
