Abstract

In this work, we present a systematic investigation of the influence of mixed-phase TiO₂ with various a-TiO₂ to r-TiO₂ ratio (A/R) toward the DSSCs efficiency. It was found that though a-TiO₂ showed better performance than r-TiO₂ in DSSCs, the Ru-bipyridine dye (N719) sensitized TiO₂ films fabricated by mixed-phase TiO₂ with A/R = 9 gives the highest cell efficiency.
