Description

General description

Titania paste, the reflector is a precursor for titania, that forms a mesoporous light scattering layer on the fluorine doped tin oxide (FTO) substrates. It is used in a variety of electrochemical devices to improve electron mobility and power efficiency.

Application

Light scattering titania paste can be coated on the primary transparent layer of TiO₂ to form a bilayered titanium film. It can be used as a negative electrode for dye sensitized solar cells (DSSCs).

Scattering Reflector Titania Paste can be used in conjunction with Transparent Titania Paste for enhanced DSSC performance in applications where transparency is not required.
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.
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.

Storage: Store in the dark at 20°C
