Abstract
The binder-free TiO2 pastes that have been developed using acid-base chemistry were reported. The TiO2 were found to exhibit viscosity as high as 5.3×104 cP, which enabled the formation of thick TiO2 films without requiring the thermal sintering effect. IPCE was measured as a function of wavelength from 400 to 800 nm using a specially designed IPCE system for dye-sensitized solar cells. It was observed that the high frequency semi-circles become featureless due to poor electrical contact between the particles in the TiO2 network.
