Triarylamine-based hydrido-carboxylate rhenium(i) complexes as photosensitizers for dye-sensitized solar cells

Ulf Anders Hagfeldt, Thomas Moehl, Kazuteru Nonomura, Lorenzo Veronese

Two new dyes based on a dinuclear rhenium complex and (E)-3-(5-(4-(bis(2,4-dibutoxy-[1,1-biphenyl]-4-yl)amino)phenyl)thiophen-2-yl)-2-cyanoacrylic acid (namely D35) have been investigated as sensitizers for dye sensitized solar cells (DSSCs). Two different ...

Influence of the Adsorption of Phycocyanin on the Performance in DSS Cells: and Electrochemical and QCM Evaluation

Michael Graetzel, Jean-David Décoppet, Thomas Moehl

The influence of some coadsorbents and different pH values on the efficiency of DSS cells assembled with phycocyanin was evaluated using quartz crystal microbalance (QCM) and electrochemical techniques as impedance spectroscopy (EIS) and cyclic voltammetry ...

Ligand Engineering for the Efficient Dye-Sensitized Solar Cells with Ruthenium Sensitizers and Cobalt Electrolytes

Mohammad Khaja Nazeeruddin, Jacques-Edouard Moser, Peng Gao, Filippo de Angelis, Thomas Moehl, Joël Teuscher, Aswani Yella, Sadig Aghazada, Gabriele Marotta

Over the past 20 years, ruthenium(II)-based dyes have played a pivotal role in turning dye-sensitized solar cells (DSCs) into a mature technology for the third generation of photovoltaics. However, the classic I3−/I− redox couple limits the performance and ...

Unraveling the Dual Character of Sulfur Atoms on Sensitizers in Dye-Sensitized Solar Cells

Mohammad Khaja Nazeeruddin, Jacques-Edouard Moser, Peng Gao, Thomas Moehl, Joël Teuscher, Aswani Yella, Sadig Aghazada

Cyclometalated ruthenium sensitizers have been synthesized that differ with number of thiophene units on the auxiliary ligands. Sensitizers possessing four (SA25, SA246, and SA285) or none (SA282) sulfur atoms in their structures, were tested in solar cell ...

Covalent Immobilization of a Molecular Catalyst on Cu2O Photocathodes for CO2 Reduction

Michael Graetzel, Peng Gao, Jingshan Luo, Thomas Moehl, Matthew Thomas Mayer, Marcel Roland Schreier

Sunlight-driven CO2 reduction is a promising way to close the anthropogenic carbon cycle. Integrating light harvester and electrocatalyst functions into a single photo electrode, which converts solar energy and CO2 directly into reduced carbon species, is ...
