Molecular gelation of ionic liquid-sulfolane mixtures, a solid electrolyte for high performance dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jean-David Décoppet, Thomas Moehl

Cyclohexanecarboxylic acid-[4-(3-tetradecylureido)phenyl]amide is an efficient gelator to solidify ionic liquid electrolytes. In this paper we apply this low molecular weight gelator to solidify the newly prepared sulfolane based ionic liquid electrolyte. ...

Mesoscopic thin films of hematite as photoanode for water photoelectrolysis

Alexis Joseph Duret

Due to the limiting amount of fossil fuel available and to the continuous growth of the world energy consumption, it becomes important to find alternative energy sources. Hydrogen produced by the photoelectrolysis of water is a perfect candidate as a clean ...
