Reflector Anatase TiO2 Paste
Paste of anatase TiO2 particles for reflection layer of DSSCs


This type of TiO2 paste contains relatively large anatase TiO2 particles, formed as a paste using a solvent and binder. The size of particles is larger than 100 nm and produce high light reflection, which is required for a reflector layer in dye sensitized solar cells. The paste can be applied by blade coating or screen printing. By thermal treatment, at around 100 °C the solvent is evaporated, at below 400 °C the binder is removed and at >500 °C nanocrystals are sintered into a sufficiently good conductivity film.
