Engineering of thiocyanate-free Ru(II) sensitizers for high efficiency dye-sensitized solar cells

Mohammad Khaja Nazeeruddin, Jacques-Edouard Moser, Filippo de Angelis, Elham Ghadiri, Kuan-Lin Wu, Shilong Wang

We synthesized a series of Ru(II) metal complexes TFRS-1, -2, -4, -21, -22 and -24 with a single 4,40- dicarboxylic acid-2,20-bipyridine together with two functionalized pyridyl azolate ancillary ligands consisting of pyrazolate or triazolate groups. Both ...

Unravelling the Potential for Dithienopyrrole Sensitizers in Dye-Sensitized Solar Cells

Mohammad Khaja Nazeeruddin, Ursula Röthlisberger, Jacques-Edouard Moser, Ivano Tavernelli, Robin Humphry-Baker, Peng Gao, Joël Teuscher, Basile Curchod, Aswani Yella, Negar Ashari Astani, Julien Edouard Frey, Lauren Elizabeth Polander

Two D−π−A dyes based on the dithieno[3,2-b:2′,3′-d]pyrrole π-bridge (DTP) were synthesized, characterized using UV−vis absorption spectroscopy and electrochemistry, modeled using quantum chemical calculations, and used as sensitizers in dye-sensitized sola ...

Precise Control of Intramolecular Charge-Transport: The Interplay of Distance and Conformational Effects

Jacques-Edouard Moser, Mateusz Barnaba Wielopolski, Lars-Hendrik Mewes

A new series of donor–bridge–acceptor (D–B–A) compounds consisting of π-conjugated oligofluorene (oFL) bridges between a ferrocene (Fc) electron-donor and a fullerene (C60) electron-acceptor have been synthesized. In addition to varying the length of the b ...

Photoinduced processes in lead iodide solid-state solar cells

Michael Graetzel, Jacques-Edouard Moser, Arianna Marchioro, Joël Teuscher, Jan Cornelius Brauer

Organic-inorganic hybrid systems based on lead halide compounds have recently encountered considerable success as light absorbers in solid-state solar cells. Herein we show how fundamental mechanistic processes in mesoporous oxide films impregnated with CH ...

Significant Improvement of Dye-Sensitized Solar Cell Performance by Small Structural Modification in π-Conjugated Donor-Acceptor Dyes

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Robin Humphry-Baker, Joël Teuscher, Magdalena Anna Marszalek, Mateusz Barnaba Wielopolski, Amaresh Mishra

Two donor-π-acceptor (D-π-A) dyes are synthesized for application in dye- sensitized solar cells (DSSC). These D-π-A sensitizers use triphenylamine as donor, oligothiophene as both donor and π-bridge, and benzothiadiazole (BTDA)/cyanoacrylic acid as accept ...

Synthesis and Characterization of High-Photoactivity Electrodeposited Cu2O solar absorber by photoelectrochemistry and ultrafast spectroscopy

Michael Graetzel, Jacques-Edouard Moser, Adriana Paracchino, Jan Cornelius Brauer

We present a systematic study on the effects of electrodeposition parameters on the photoelectrochemical properties of Cu2O. The influence of deposition variables (temperature, pH, and deposition current density) on conductivity has been widely explored in ...
