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 ...

Multicolor Single Molecule Tracking of Stochastically Active Synthetic Dyes

Suliana Manley, Aleksandr Benke

Single particle tracking can reveal dynamic information at the scale of single molecules in living cells but thus far has been limited either in the range of potential protein targets or in the quality and number of tracks attainable. We demonstrate a new ...

Tuning spectral properties of phenothiazine based donor-pi-acceptor dyes for efficient dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Robin Humphry-Baker, Magdalena Anna Marszalek

Two novel metal-free organic donor-pi-acceptor dyes were synthesized using electron-rich 10-butyl-(2-methylthio)-10H-phenothiazine as a donor and cyanoacrylic acid as an acceptor. The spectral response of the dye was tuned by introducing a vinylene thiophe ...

A New Heteroleptic Ruthenium Sensitizer for Transparent Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Thomas Moehl, Nuttapol Pootrakulchote, Miao Chen

A new heteroleptic ruthenium complex, coded CYC-B19, incorporating an ancillary ligand endowed with hexylthio-bithiophene segments and a conjugated anchoring ligand with vinyl groups was prepared. This new sensitizer exhibits a lower energy MLCT band centr ...

Phenoxazine dyes for dye-sensitized solar cells: relationship between molecular structure and electron lifetime

Xiaoqing Jiang, Ulf Anders Hagfeldt

A series of metal-free organic dyes with a core phenoxazine chromophore have been synthesized and tested as sensitizers in dye-sensitized solar cells. Overall conversion efficiencies of 6.03-7.40% were reached under standard AM 1.5G illumination at a ligh ...

On the Applicability of Oil and Dye Technique During the Design Phase and Operation of Experimental Rigs

Alexandros Terzis

In this paper, an oil and dye flow visualization technique applied in two different cases of experimental testing is described, namely a single fan in crossflow and the wake of a compressor cascade. In both cases, the mixture of paint was prepared using a ...

A starter kit for point-localization super-resolution imaging

Suliana Manley, Julia Gunzenhäuser

Super-resolution fluorescence imaging can be achieved through the localization of single molecules. By using suitable dyes, optical configurations, and software, it is possible to study a wide variety of biological systems. Here, we summarize the different ...

The influence of dye structure on charge recombination in dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Yuhang Liu

Replacing the nonyl groups on the solar cell dye Ru(4,4'-carboxylic acid-2,2'-bipyridine)-( 4,4'-dinonyl-2,2'-bipyridine)(NCS)(2) (Z-907) with amino groups results in a marked decrease in solar cell performance. This is despite the fact that the amino deri ...

Coumarin dyes containing low-band-gap chromophores for dye-sensitised solar cells

Mohammad Khaja Nazeeruddin, Filippo de Angelis

A series of coumarin dyes containing a low-band-gap chromophore of ethylenedioxythiophene (EDOT), which comprises a coumarin moiety as the electron donor and a cyanoacrylic acid moiety as electron acceptor in D-pi-A chromophores, were developed for use in ...

Modifying organic phenoxazine dyes for efficient dye-sensitized solar cells

Xiaoqing Jiang, Ulf Anders Hagfeldt

Four org. dyes bearing the phenoxazine chromophore have been synthesized and applied in dye-sensitized solar cells (DSCs). The effect of different dye structures on the performance of the DSCs was investigated systematically with photophys., photovoltaic a ...
