2. Inkjet printing of Ag-inks
Nanoparticle
based inks
Ag nanoparticles capped with a polymer layer
Molecular precursor inks
Ag+ complexes

3. Sintering Nanoparticle “high” temperature > 200 °C
Molecular precursor
low temperature
60 °C
Ag+  Ag

4. Sheet resistance Nanoparticle 10 m/□  Molecular precursor 17 /□
6 layers
8 layers
10 layers
Glass
PET-foil

5. Roughness
Nanoparticle OK
Molecular precursor
too high

6. Conclusions Low temperature sintering: 60 °C
PET-foil
Heat sensitive devices
Acceptable sheet resistances achieved
Roughness subject further research
