Title
Aqueous dye-sensitized solar cell electrolytes based on the ferricyanide-ferrocyanide redox couple
Document Type
Journal Article
Abstract
The application of water as solvent in dye-sensitized solar cell (DSC) electrolytes is highly attractive due to its non-toxicity, non-flammability and excellent solvation of many potential redox mediators. However, the current consensus is that water is an undesirable contaminant in DSC electrolytes as it leads to the formation of iodate, dye desorption, low device efficiencies and device instability. While this holds true for the majority of dyes investigated previously, we demonstrate herein that a carbazole dye performs exceptionally well in DSCs constructed with aqueous electrolytes, and that efficiencies of over 4% can be reached by applying the ferricyanide–ferrocyanide redox couple.
