Abstract
We reported a composite electrolyte prepared by incorporating layered a-titanium phosphate (a-TiP) into a binary ionic liquid of
1-propyl-3-methylimidazolium iodide (PMII) and 1-ethyl-3-methylimidazolium tetrafluoroborate (EmimBF4) (volume ratio, 13:7) electrolyte.
The addition of a-TiP markedly improved the photovoltaic properties of dye-sensitized solar cells (DSSCs) compared to that
without a-TiP. The enhancement was explained by improved diffusion of tri-iodide ðI
3 Þ ions, suppressed electron recombination with
I
3 in the electrolyte and increased lifetime of electrons in mesoscopic TiO2 film.
