Abstract

Metal-free dyes (EO1 to EO4) containing the hydrophilic triethylene oxide methyl ether (TEOME) unit in the spacer have been synthesized and used in dye-sensitized solar cells (DSSCs). Efficient lithium-ion trapping by TEOME results in improved open-circuit voltage (V_OC), leading to excellent conversion efficiency of the cells, ranging from 9.02 to 9.98% with I^-/I₃^- electrolyte in acetonitrile under AM1.5 illumination. The TEOME unit also enhances the wettability of the dye molecules for application in aqueous-based DSSCs. Aqueous-based DSSCs with a dual TEMPO/iodide electrolyte exhibit high V_OC values (0.80-0.88V) and very promising cell performances of up to 5.97%.
