Branched and bulky substituted ruthenium sensitizers for dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Aravind Kumar Chandiran

We report on the synthesis, and photovoltaic performances of four novel Ru(II)-bipyridine heteroteptic complexes TT206-209, incorporating branched and bulkier alkyl chains compared to their linear analogues C106 and CYC-B11 previously reported. In both ser ...

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. ...

4,9-Dihydro-4,4,9,9-tetrahexyl-s-indaceno[1,2-b:5,6-b ']dithiophene as a pi-Spacer of Donor-pi-Acceptor Dye and Its Photovoltaic Performance with Liquid and Solid-State Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jean-David Décoppet, Robin Humphry-Baker, Thomas Moehl, Soo-Jin Moon

A new D-pi-A organic dye, LC-5, containing 4,9-dihydro-4,4,9,9-tetrahexyl-s-indaceno[1,2-b:5,6-b']-dithiophene as a novel pi-conjugated spacer has been synthesized and tested as a sensitizer in dye-sensitized solar cells (DSC). Volatile and ionic liquid el ...

Molecular Engineering of 2-Quinolinone Based Anchoring Groups for Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Peng Gao, Aravind Kumar Chandiran, Paramaguru Ganesan

Six new donor-pi spacer-acceptor (D-pi-A) organic sensitizers based on the 2-quinolinone moiety as acceptor and anchoring groups were synthesized and tested for their performance in dye-sensitized solar cells (DSSCs). The systematic tuning of acceptor stre ...

Comparative studies on rigid π linker-based organic dyes: Structure-property relationships and photovoltaic performance

Ho Ling Li, Ulf Anders Hagfeldt, Yan Hao

© 2014 Wiley-VCH Verlag GmbH & Co. KGaA. A series of six structurally correlated donor-π bridge-acceptor organic dyes were designed, synthesized, and applied as sensitizers in dye-sensitized solar cells. Using the most widely studied donor (triarylamine) a ...

Lanthanides in Solar Energy Conversion

Jean-Claude Bünzli, Anne-Sophie Chauvin

Solar energy represents an abundant (1000 W·m-2) and seemingly cheap source of energy. One way to tap it is to transform light into electricity with photovoltaic devices. Single junction solar cells presently reach 32% conversion yield under 1-sun illumina ...

Low temperature crystalline titanium dioxide by atomic layer deposition for dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Pascal Comte, Aswani Yella, Morgan Mertens Stefik, Aravind Kumar Chandiran, Leo-Philipp Heiniger

Low temperature processing of dye-sensitized solar cells (DSC) is crucial to enable commercialization with low-cost, plastic substrates. Prior studies have focused on mechanical compression of premade particles on plastic or glass substrates, however, this ...

Tridentate cobalt complexes as alternative redox couples for high-efficiency dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Thomas Moehl, Kaïs Ben Aribia

Cobalt terpyridine complexes could rival the classical triiodide/iodide redox couple as efficient alternative redox couples for dye-sensitized solar cells. Cobalt bis(2,2',6',2 ''-terpyridine) complexes enable systematic tuning of the redox potential by va ...
