Application of Cu(II) and Zn(II) coproporphyrins as sensitizers for thin film dye sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Mingkui Wang, Pascal Comte, Davide Di Censo, Joël Teuscher

We synthesized the Cu(II) and Zn(II) complexes of the 2,7,12,17-tetrapropionic acid of 3,8,13,18-tetramethyl-21H,23H porphyrin (coproporphyrin-I) and successfully employed them as sensitizers in dye-sensitized solar cells. Copper(II) coproporphyrin-I exhib ...

Employ a bisthienothiophene linker to construct an organic chromophore for efficient and stable dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Peng Wang, Yu Bai, Sophie Wenger

We employed the bisthienothiophene conjugated linker along with a hydrophobic triphenylamine electron-donor and a hydrophilic cyanoacrylic acid electron-acceptor to construct a high molar extinction coefficient organic photosensitizer, exhibiting a power c ...

Trajectory Tracking through Overactuation for an Optical Delay Line

Denis Gillet, Philippe Müllhaupt

Nano-positioning devices constitute the mechatronic heart of the VLTI (Very Large Telescope Interferometer) for the ESO (European Southern Observatory) astrometry instrumentation. In the context of the development of a new optical Differential Delay Line ( ...

Conformational dependence of intramolecular vibrational redistribution in methanol

Thomas Rizzo, Oleg Boyarkine, Pavlo Maksyutenko

Previous state-selected spectra of methanol in the 5ν1 OH stretch overtone region [O. V. Boyarkin, T. R. Rizzo, and D. S. Perry, J. Chem. Phys. 110 (23), 11346 (1999)] revealed structure indicating intramolecular vibrational redistribution (IVR) on three t ...
