Effect of the TiO₂ Anchoring of a Hydrophobic Ionic Liquid in a Fully Aqueous DSSC

Recent advances in eco-friendly and cost-effective materials towards sustainable dye-sensitized solar cells

“…This represents a hindrance for the scalability of the manufacturing process, particularly when an easier processability is claimed for DSSC technology with respect to other PV devices. Notably, Fe forms several complexes that are soluble in water, thus its use in green, aqueous-based DSSCs can be envisaged, 104,219 as will be discussed in section 2.2.2. One of the first devices based on iron complexes as redox mediators was reported by Daeneke et al, 104 who demonstrated the use of a ferricyanide/ferrocyanide (Fe(CN) 6 4−/3− ) redox couple, using water as the solvent and proposing this electrolyte as non-corrosive.…”
