INSULATION LAYER IN MONOLITHIC DYE SOLAR CELL ASSEMBLY

Zr-Nanoxide ZR/SP

A screen printing zirconium dioxide paste for the deposition of insulating layers in monolithic Dye Solar Cells.

Firing the paste at 500°C yields an opaque white layer, that remains porous, with a minimal dye uptake. This allows for titania staining in the presence of an insulating zirconia layer, and offers good electrolyte penetration throughout the entire electrode stack at device assembly.

Load: ~30wt%
Particle size: 20-40 nm mixed with 5 µm
Vehicle: terpineol, organic binders

INSULATION LAYER IN MONOLITHIC PEROVSKITE SOLAR CELL ASSEMBLY

Zr-Nanoxide ZT/SP

A screen printing zirconium dioxide nanoparticle paste for the deposition of insulating layers in monolithic Perovskite Solar Cells.

After firing at 500°C, the oxide particles form a mesoporous coating allowing for perovskite impregnation of the underneath layers.

Thanks to a composition exclusively made of nanoparticles, the resulting zirconia layers can be extremely thin, down to the micron, whilst ensuring electrical insulation without sacrificing device thinness and charge extraction.

Load: ~18wt%
Particle size: 20-40 nm
Vehicle: terpineol, organic binders

MESOPOROUS INSULATION LAYER

Zr-Nanoxide ZT/DC

A slot-die coating formulation for the deposition of insulating mesoscopic zirconium dioxide layers.

Slot-die coating at 0.5 m/min, 0.2 mL/min typically yields a 500 nm thick layer after firing at 500°C for 45 min.

Load: ~6.75wt%
Particle size: 20-40 nm
Vehicle: terpineol, alcohols, organic binders
