Nanocomposite Semi-Solid Redox Ionic Liquid Electrolytes with Enhanced Charge-Transport Capabilities for Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Magdalena Anna Marszalek

The ability of Pt nanostructures to induce the splitting of the I-I bond in iodine (triiodide) molecules is explored here to enhance electron transfer in the iodine/iodide redox couple. Following the dispersal of Pt nanoparticles at 2% (weight) level, char ...

Measured binding coefficients for iodine and ruthenium dyes; implications for recombination in dye sensitised solar cells

Shaik Mohammed Zakeeruddin, Robin Humphry-Baker, Xiong Li

We have measured the binding coefficients of iodine to three dyes used in Dye Sensitised Solar Cells (DSSCs). Binding coefficients are quantified via the effect of iodine binding on the UV-vis spectrum of the dye. From iodine titration curves of dye sensit ...

Conduction Through Viscoelastic Phase in a Redox-Active Ionic Liquid at Reduced Temperatures

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jan Cornelius Brauer

The phase diagram of the redox active ionic liquid 1-methyl-3-propylimidazolium iodide (PMII) is examined as a function of temperature and iodine concentration. Beyond a threshold concentration of 3.9 M, the formation of higher polyiodides gives rise to a ...

Fluorine in an heteroaromatic context : functionalization of halopyridines

Thierry Rausis

The organometallic approach to the functionalization of arenes and heteroarenes has recently been investigated by our group introducing modifications of the standard methods. This includes, in particular, the basicity-driven heavy halogen migration, which ...
