This paper reports a new D-A-pi-A organic dye WS-9, which is derived from the known dye WS-2 by incorporating an n-hexylthiophene unit into the pi-conjugation. Due to the presence of a strong electron-withdrawing benzothiadiazole unit in the pi-bridge, the ...

Photoinduced mol. rearrangements are important in daily events essential for life such as visual perception and photo-protection of light harvesting complexes in plants. In this study we demonstrate that similar photorearrangements appear in an analogous t ...

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

Shaik Mohammed Zakeeruddin, Robin Humphry-Baker, Filippo de Angelis, 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 ...

Solid-State Sensitized Heterojunction Solar Cells

Soo-Jin Moon

Dye-sensitized solar cells (DSCs) are considered as an emerging technology in order to replace conventional silicon solar cells or thin film solar cells such as amorphous silicon, CIGS, and CdTe. Liquid electrolytes containing iodide/triiodide redox couple ...

EPFL2011

The absorption spectra of most org. dyes reported thus far used for mesoporous nanostructured dye-sensitized solar cells mainly cover the visible-light region. This has motivated research towards the development of new types of org. dyes(7-10) with absorpt ...

Design and Development of Functionalized Cyclometalated Ruthenium Chromophores for Light-Harvesting Applications

Michael Graetzel, Mohammad Khaja Nazeeruddin, Aswani Yella, Thomas Baumgartner

The syntheses and the electrochemical spectroscopic properties of a suite of asymmetrical bistridentate cyclometalated Ru(II) complexes bearing terminal triphenylamine (TPA) substituents are reported. These complexes, which contain structural design elemen ...

Dye-sensitized solar cells (DSCs) constitute a novel class of hybrid organic-inorganic solar cells. At the heart of the device is a mesoporous film of titanium dioxide (TiO2) nanoparticles, which are coated with a monolayer of dye sensitive to the visible ...

EPFL2010

One-electron outer-sphere redox couples, such as ferrocene/ferrocenium, are an interesting alternative to the iodide/triiodide redox couple that is normally employed in dye-sensitized solar cells (DSCs) because they should reduce the driving force needed t ...

Metal-free org. dyes bridged by anthracene-contg. π-conjugations were designed and synthesized as new chromophores for dye-sensitized solar cells (DSSCs). Studies on the relation between the dye structure, photophys. properties, electrochem. properties and ...

Influence of Sodium Cations of N3 Dye on the Photovoltaic Performance and Stability of Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin

We report on the effect of substituting the two tetrabutyl ammonium counter ions of the standard N719 dye by sodium ions on the performance and stability of dye-sensitized solar cells (DSCs). The disodium analogue of N719 in conjunction with a non-volatile ...
