General description

Helios′Ink H-DZ41006 semiconductive ink developed for the printed electronics is particularly well suited for OPV and PV.
This ink shows great performance on spin coating and slot die coating and is compatible with various flexible substrates (Kapton,® PET, PET/ITO, etc.) but also glass/ITO.
The use of Helios′Ink H-DZ41006 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-DZ41006 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.
Drying conditions: Oven, IR oven, vacuum oven.
Clean-up solution: Ethanol/Acetone.
