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 ...

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 ...

Optically Transparent FTO-Free Cathode for Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Paul Liska, Ladislav Kavan

The woven fabric containing electrochemically platinized tungsten wire is an affordable flexible cathode for liquid-junction dye-sensitized solar cells with the I-3(-)/I- redox mediator and electrolyte solution consisting of ionic liquids and propionitrile ...

Amer Chemical Soc2014

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 ...

Two new organic D-pi-A dyes containing identical pi-conjugated spacer and anchoring/acceptor moieties but different donor groups were designed and synthesized. These dyes containing didodecylcyclopentadithiophene (CPDT) as a spacer, cyanoacrylic acid as an ...

RSC Publishing2013

Linker unit modification of donor-linker-acceptor-based org. dyes was investigated with respect to the spectral and physicochem. properties of the dyes. The spectral response for a series of triphenylamine (TPA)-based org. dyes, called LEG1-4, was shifted ...
