Silver Nano inks vs Flakes inks

Silver nano inks

• Particles size : < 50nm• Low sintering

temperature• Light absorption suitable

for photonic curing• Suitable to address

different printing methods

• Resistivity : < 3,5 µΩ.cm• Flexible: conducive even if

folded

Silver flakes inks

• Particles size : > 2µm• Resistivity : more than 15

times the silver bulk resistivity

• The ink is just cured

Nano inks vs Flakes inks Curing comparison

SILVER FLAKES

Before curing: large particles

with lot of empty space.

SILVER NANO

Before curring : high density

of particles without any

curing.

After curing After curing

How to outperform ITO film?

Coating of ZnO

AFM Silver nanowires AFM Silver nanowires+ ZnO

ZnO nanoparticles Very high efficiency in ETL layer Decrease the roughness of silver

nanowires Increase the conductivity of silver

nanowires

Results :Transmission > 85%R = 20 Ω/sq

V3.0.18122014 Genes’Ink proprietary information

AZO Nano inks vs standard ETL

AZO nanoparticles Very high efficiency in ETL layer at high

thickness (>100nm) Very low roughness (<3nm)

IV. An invisible electronic :

Clearsilver

ITO limit and the solution

The Indium Tin Oxyde (ITO) as some limit:

• ITO: from rare metal

• ITO: not-foldable

• ITO: vacuum deposition (PVD)

The solution coming through printed electronic and ink:

• 1 layer of Nanowire covered by one layer of AZO

• 1 layer of combined solution of Nanowired and AZO

• 1 printed grid of silver covered by one layer of AZO ClearSilver

The goal of this project is to develop an industrial solution for the production of large R2R inkjet printed electronics.

– CLEARSILVER will produce a flexible and Transparent Conductive Films (TCF) for OPV and OLED lighting

– The solution proposes inkjet printed Ag grid covered with ZnO nanoink onto polymer films

Industrial scale production of nanoinks.Industrial scale printing tools

V3.0.18122014 Genes’Ink proprietary information

Enable the use of nanoinks at an industrial scale:

In the industry, there is no process for mass production, only lab quantities are available.

Genes’Ink capacity will be raised up to > 10 000 litres per year (2 millions m2).

Develop an industrial inkjet printing solution with:

A high printing speed of 40 m/min compared to few mm/min of current lab machines. We are now at 10 m/min on a pilot KSCAN PE300 KT printer (TRL6).

A high resolution, less than 10 µm width ± 1 µm on large area (1 m web). Achieved actual resolution is 50 µm ± 2 µm (320 mm web).

A capacity to print at high speed inks containing between 15 to 40 % of solid content.
