Nanocrystalline Titanium Dioxide TiO2 Product Details

Nanocrystalline Colloidal Titanium Dioxide Paste

Nanocrystalline Titanium Dioxide TiO2 Deposition methods

Our pastes can be used in laboratory and mass-production nanoporous deposition techniques including screen printing, doctor-blading and spin coating. Benefits Improved solar conversion efficiency – High purity < 10ppm of Fe, K and Na Crystal purity 96-98% anatase. A range of aqueous based for safer handling Near zero volatile organic compounds Does not require any post TiCl4 treatment Achieve high performance using a single coating step with opaque TiO2 colloids Removes the need for making mechanically weak secondary light scattering layer.

*Verified by independent tests by École polytechnique fédérale de Lausanne.

Nanocrystalline Titanium Dioxide TiO2 Characteristics

Titanium dioxide (TiO2) can be used in the creation of photoelectrodes for the production of Dye Sensitized, Perovskite and other solid state solar cells. Improved solar efficiency we offer a range of transparent and opaque colloid TiO2 pastes with a narrow particle size distribution for improved solar conversion efficiency. These performance improvements have been verified by École Polytechnique Fédérale de Lausanne.

Characteristics – Our TiO2 include high anatase purity, variable light trapping characteristics with transparent or opaque coating options. Our range includes colloidal TiO2 pastes that are aqueous based for safer handling and improved environmentally friendliness. In addition our TiO2 pastes do not require any post TiCl4 treatment.

Particle & Pore Sizes – Tunable particle sizes from 18 – 30 nm are available upon request. Formulations can also be targeted to achieve the tunable pore volume needed for emerging solid state solar cells based on Perovskite and other light absorbers. MS033 Revision 2 Issue date August 2014.
