Blocking Layer Titania Paste can be used as an n-type blocking layer in a variety of ssDSC, perovskite, and other mesoporous solar cells, and is fully compatible with traditionally used “compact” (TiCl₄”) layers either prior to or subsequent to deposition and processing of the blocking layer.
Specifications:

Use 18NR-AO Active Opaque Titania Paste in applications that do not require transparency.

The dispersed scattering particles in 18NR-AO Active Opaque Titania Paste formulation lead to better DSC performance through the large surface/volume ratio of the sintered film.
18NR-AO Active Opaque Titania Paste has a blend of active anatase particles (~20nm) and larger anatase scatter particles (up to 450nm).
After drying, this paste must be fired at or above 500°C. This results in an opaque sintered layer with film thickness of 7-8μm for one printed layer and ~15μm for two layers, when using a 48T mesh.
This paste exhibits optimal rheological properties that provide good surface uniformity and contain organic binders specially formulated to provide versatile porosity suitable for a range of dye/electrolyte systems.

Specifications:

Use CELS Counter-Electrode Solution in applications that require a highly transparent layer with high electrocatalytic activity.
CELS Counter-Electrode Solution paste has been formulated to have a low viscosity, allowing application by brush painting, spin-coating or spraying.
After drying, this paste must be fired at or above 420°C. This results in uniformly distributed platinum nanoclusters providing good transparency and high catalytic activity for the electrochemical reduction of I3- to I-.

Specifications:

Use 30 NR-D Transparent Titania Paste in applications that require a transparent sintered Titania film with a large surface/volume ratio.

30 NR-D Transparent Titania Paste is formulated to yield sintered film thicknesses of 6-7μm when screen printed with a 43T mesh. 30 NR-D Transparent Titania Paste has highly dispersed and stable anatase nanoparticles.

It is optimized for screen printing using a synthetic 43T mesh screen (or similar). After drying, this paste must be fired at or above 500°C. This results in a transparent sintered layer, with a film thickness of approximately 6-7μm for one printed layer and ~12μm for two printed layers, when using a 43T mesh screen.

The paste exhibits optimal rheological properties that provide good surface uniformity and contains organic binders specially formulated to provide versatile porosity suitable for a range of dye/electrolyte systems.

Specifications:

Use WER2-O Scattering Titania Paste in conjunction with 18NR-T Transparent Titania Paste or 90-T Transparent Titania Paste (Thin Use) for enhanced DSC performance in applications where transparency is not required.
WER2-O Scattering Titania Paste contains highly dispersed anatase scattering particles (150nm to 250nm). This paste produces a non-active scattering layer when applied onto a pre-printed active layer.

This scattering paste is ideally printed in combination with 18NR-T Transparent Titania Paste or 90-T Transparent Titania Paste (Thin Use).

After drying, this paste must be fired – together with the pre-printed active layers – at or above 500°C. This results in an opaque sintered layer, with a thickness of ~3μm for one printed layer, when using a 90T mesh screen.

Specifications:

Use PT1 Platinum Paste in applications that require a highly transparent layer with high electrocatalytic activity.
PT1 Platinum Paste has been formulated to be applied using a screen printer, providing films with excellent uniformity and reproducibility.

PT1 Platinum Paste is oil-based and formulated for screen printing using a synthetic 100T mesh screen (or similar).

After drying, this paste must be fired at or above 420°C. This results in uniformly distributed platinum nanoclusters, providing good transparency and high catalytic activity for the electrochemical reduction of I3- to I-.

PT1 Platinum Paste provides films with excellent uniformity and performance, virtually independent of the operator, and can be used for DSC pilot production.

Specifications:

Use 90-T Transparent Titania Paste (Thin Use) in applications that require a transparent sintered titania films with large surface/volume ratios.

90-T Transparent Titania Paste (Thin Use) is formulated to yield sintered film thicknesses of approximately 3μm when screen printed with a 90T mesh.

90-T Transparent Titania Paste (Thin Use) has highly dispersed and stable anatase nanoparticles. After drying, this paste must be fired at or above 500°C. This results in a transparent sintered layer, with a thickness of 3μm for one printed layer when using a 90T mesh screen.

The paste exhibits optimal rheological properties that provide good surface uniformity and contain organic binders specially formulated to provide versatile porosity suitable for a range of dye/electrolyte systems.

Specifications:
