Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The thiolate/disulfide organic redox couple (McMT⁻/BMT), derived from 2‐mercapto‐5‐methyl‐1, 3, 4‐thiadiazole (McMT), recently proposed as an alternative to usual inorganic couples in dye‐sensitized solar cells, exhibits a remarkable reversibility and stability in a thermogalvanic cell containing a 1‐ethyl‐3‐methyimidazolium tetrafluoroborate/acetonitrile (EMIMBF₄/AN) mixture. The thermoelectric power depends strongly on concentrations of both the ionic liquid and the redox couple. It is enhanced by a factor of six at high ionic‐liquid concentrations. The control of these parameters can be used to enhance the thermopower and the thermoelectric efficiency of future ionic‐liquid thermocells.</p> </abstract>
