Dye-sensitized solar cells based on cobalt-containing room temperature ionic liquid redox shuttles
An imidazolium-based co-containing room temperature ionic liquid, bis(3-butyl-1-methylimidazolium) tetraisothiocyanato cobalt [BMI]2[Co(NCS)4], was synthesized and characterized. The prepared [BMI]2[Co(NCS)4]/1-propyl-3-methylimidazolium iodine (PMII) hybrid redox couple showed higher redox potential than that of the iodide/triiodide (I /I3 ) redox couple. The resultant dye-sensitized solar cel...
متن کاملDye-sensitized solar cells: driving-force effects on electron recombination dynamics with cobalt-based shuttles.
A series of cobalt-containing redox couples, based on [Co(1,10-phenanthroline)(3)](ClO(4))(2) and its derivatives, were prepared for use as regenerators/shuttles in dye-sensitized solar cells featuring modified TiO(2) photoelectrodes. Surface modification and trap-state passivation of the TiO(2) nanoparticle film electrodes were accomplished via atomic layer deposition of an ultrathin alumina c...
متن کاملIonic Liquid Based Electrolytes for Dye-Sensitized Solar Cells
1.1 New type of solar cell: dye-sensitized solar cells (DSSCs) The rising price of fossil fuels, together with their rapid depletion and the pollution caused by their combustion, is forcing us to find sources of clean renewable energy. Fortunately, the supply of energy from the sun to the earth is gigantic, i.e., 3 × 1024 joule a year or about ten thousand times more than what mankind consumes ...
متن کاملA quasi-liquid polymer-based cobalt redox mediator electrolyte for dye-sensitized solar cells.
Recently, cobalt redox electrolyte mediators have emerged as a promising alternative to the commonly used iodide/triiodide redox shuttle in dye-sensitized solar cells (DSCs). Here, we report the successful use of a new quasi-liquid, polymer-based electrolyte containing the Co(3+)/Co(2+) redox mediator in 3-methoxy propionitrile solvent in order to overcome the limitations of high cell resistanc...
متن کاملIonic liquid electrolytes for dye-sensitized solar cells.
The potential of room-temperature molten salts (ionic liquids) as solvents for electrolytes for dye-sensitized solar cells has been investigated during the last decade. The non-volatility, good solvent properties and high electrochemical stability of ionic liquids make them attractive solvents in contrast to volatile organic solvents. Despite this, the relatively high viscosity of ionic liquids...
