Eco‐Friendly Sugar‐Based Natural Deep Eutectic Solvents as Effective Electrolyte Solutions for Dye‐Sensitized Solar Cells

Dye‐sensitized solar cells containing sugar‐based natural deep eutectic solvents (NADESs) as active electrolyte solvents have been studied in terms of their photovoltaic (PV) properties, including main PV characteristics, incident photon‐to‐current efficiency, and impedance properties. Five monosaccharides were selected as NADES H‐bond donors and investigated with a phenothiazine‐based sensitizer carrying a glucose functionality and a...
