Application

Titanium dioxide (TiO2) is used in the creation of photoelectrodes for the production of dye sensitized perovskite and other solid state solar cells. Our TiO2 pastes allow deposition of titania films with large surface to volume ratio. Select transparent TiO2 paste for applications that require a transparent sintered titania film and use opaque TiO2 paste for applications that do not require transparency. The opaque TiO2 paste contains larger scattering TiO2 particles.
