Abstract EN
Low-cost water-based P25-TiO2 pastes were formulated and used to produce porous TiO2 films in application to the fabrication of dye-sensitized solar cells.
The structural properties of the films were characterized using a variety of techniques such as stylus profilometry, FEG-SEM imaging, BET surface area, and BJH pore size analyses.
These were compared to films produced from a commercial paste, DSL 18 NR-AO (Dyesol).
The major difference was in the fraction of macroporosity: 23% of the total pore volume for films produced with the commercial material and 67–73% for the P25-TiO2 films owing to the vast difference in dispersion and size distribution of the particles in the two types of pastes.
The macroporosity was found to have a dramatic effect on the dye diffusion kinetics measured using in situ UV-Vis reflectance spectroscopy.
The sensitization of P25-based films was much faster for heavily macroporous P25-TiO2 films (>90% saturation at 15–35 mins) than for their commercial analogue (>90% saturation at 110 mins).
DSC devices built with optimized P25-TiO2 photoanodes showed better performance at short dye immersion time (30 mins and 1 hr) due to faster percolation of the dye molecules through the film.
