Key Features

  • Can be used on a variety of  substrates, both flexible and rigid
  • Suitable for many optoelectronic devices that require transparent conductors
  • Allows transmittance of visible, UV, IR, and NIR wavelengths
  • Not brittle like ITO – better for flexible electronics
  • A simple printing process that can use a variety of conductive inkjet inks

Development Milestones

Seeking funding for utilization in optoelectronic and electronic devices , and for up-scaling of printable surface area

 

The Opportunity

  • Increasing numbers of optoelectronic devices such as flexible displays for touch screens, smart windows require transparent conductors that can be fabricated by low cost processes.
  • The process requires very little amount of material, and is performed by a direct printing process which is suitable for a variety of substrate and at large format.
