Description générale

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

Ruthenium-based dyes for Dye-sensitized Solar Cells

Dye-sensitized solar cells (DSCs) are 3rd generation solar cells combining the promise of high efficiency with low production costs.

Inverted Organic Photovoltaic Devices Using Zinc Oxide Nanocomposites as Electron Transporting Layer Materials

Organic photovoltaics (OPVs) represent a low-cost, lightweight, and scalable alternative to conventional solar cells. While significant progress has been made in the development of conventional bulk heterojunction cells, new approaches are required to achieve the performance and stability necessary to enable commercially successful OPVs.

Understanding and Successfully Applying Materials for Dye-Sensitized Solar Cells

While dye sensitization as the basis for color photography has been accepted for a very long time,1 attempts to use this principle for the conversion of solar light to electricity generally had resulted only in very low photocurrents, below 100 nA/cm
