Improvement of Thiolate/Disulfide Mediated Dye-Sensitized Solar Cells through Supramolecular Lithium Cation Assembling of Crown Ether

摘要

A supramolecular lithium cation assemblies of crown ether, [Li⊂12-crown-4]⁺, has been used to replace conventional tetraalkylammonium counterion in thiolate/disulfide (ET⁻/BET) mediated dye-sensitized solar cells (DSCs), which exhibit high stability and efficiency of 6.61% under 100 mW·cm⁻² simulated sunlight illumination.
