Solar green technology : The cover picture illustrates a nature‐inspired, low‐cost dye‐sensitized solar cell (DSSC) for renewable energy generation. The device in this work is the first based on an aqueous choline chloride/glycerol eutectic mixture (deep eutectic solvent, DES) as an effective and innovative electrolyte solvent. DESs are being tested in many fields of chemistry; this paper shows a proof of concept that DESs can be successfully employed also in the solar energy field. By combining a DES with a proper hydrophilic sensitizer, comparable power conversion efficiencies were obtained with respect to those furnished by traditional solar DSSC devices using hazardous, toxic, and volatile solvents. More details can be found in the Full Paper by Vito Capriati, Alessandro Abbotto et al. from the University of Milano‐Bicocca on page 345 in Issue 2, 2017 (DOI: 10.1002/ente.201600420).
