General description

Helios′Ink H-SZ01034, semi conductive ink developed for the printed electronics is particularly well suited for OPV and PV. Helios′Ink H-SZ01034, semi conductive ink shows great performance on Drop on Demand (DOD) inkjet printers, blade coating, and spin coating and is compatible with various flexible substrates (polyimide, PET, PET/ITO, etc.) but also Glass/ITO.

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.
  • Thin layers are obtained (20 nm) with low roughness (RMS = 3±1 nm).

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.
