Dye‐sensitized solar cells (DSSCs) that use an aqueous (40 % w / w water content) choline chloride based deep eutectic solvent as an electrolyte medium have been investigated. The joint combination of the eutectic mixture and an appropriate hydrophilic sensitizer afforded a DSSC with a power conversion efficiency comparable to that using the same electrolyte composition but with conventional, toxic, and volatile solvents as the medium, which thereby paves the way to a new generation of eco‐friendly, nature‐inspired, low‐cost solar devices.
