The Fate of Electron–Hole Pairs in Polymer:Fullerene Blends for Organic Photovoltaics

Jacques-Edouard Moser, Natalie Renuka Banerji, Jan Cornelius Brauer, Mariateresa Scarongella, Jelissa Risse, Natalie Stingelin, Martina Causa'

There has been long-standing debate on how free charges are generated in donor:acceptor blends that are used in organic solar cells, and which are generally comprised of a complex phase morphology, where intermixed and neat phases of the donor and acceptor ...

Copper Bipyridyl Redox Mediators for Dye-Sensitized Solar Cells with High Photovoltage

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Nikolaos Vlachopoulos, Fabrizio Giordano, Ulf Anders Hagfeldt, Ladislav Kavan, Norman Pellet, Yiming Cao, Yasemin Saygili, Marina Freitag, Magnus Söderberg

Redox mediators play a major role determining the photocurrent and the photovoltage in dye-sensitized solar cells (DSCs). To maintain the photocurrent, the reduction of oxidized dye by the redox mediator should be significantly faster than the electron bac ...

Ultrafast charge separation dynamics in opaque, operational dye-sensitized solar cells revealed by femtosecond diffuse reflectance spectroscopy

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Ulf Anders Hagfeldt, Elham Ghadiri

Efficient dye-sensitized solar cells are based on highly diffusive mesoscopic layers that render these devices opaque and unsuitable for ultrafast transient absorption spectroscopy measurements in transmission mode. We developed a novel sub-200 femtosecond ...

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 ...

Synthesis and optoelectronic properties of chemically modified bi-fluorenylidenes

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

The development of new light harvesting materials is a key issue for the progress of the research on organic & hybrid photovoltaics. Here, we report a new class of organic sensitizers based on the bi-fluorenylidene moiety as p-linker within the donor–p-lin ...

Unreacted PbI2 as a Double-Edged Sword for Enhancing the Performance of Perovskite Solar Cells

Jacques-Edouard Moser, Kurt Schenk, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Joël Teuscher, Juan-Pablo Correa-Baena, Marine Eva Fedora Bouduban, Tor Jesper Jacobsson, Elham Halvani Anaraki

Lead halide perovskites have over the past few years attracted considerable interest as photo absorbers in PV applications with record efficiencies now reaching 22%. It has recently been found that not only the composition but also the precise stoichiometr ...

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 ...

Self-Tracking Solar Concentrator Device

Jacques-Edouard Moser, Christophe Moser, Volker Günter Zagolla

A device for self-tracking a light source, including a focusing optical device configured to focus incoming light to a focal spot, an adaptive device configured to reflect the light of the focal spot and arranged to provide for a phase change at an area of ...

Beyond Vibrationally Mediated Electron Transfer: Coherent Phenomena Induced by Ultrafast Charge Separation

Jacques-Edouard Moser

Wave packet propagation succeeding electron transfer (ET) from alizarin dye molecules into the nanocrystalline TiO2 semiconductor has been studied by ultrafast transient absorption spectroscopy. Because of the ultrafast time scale of the ET reaction of abo ...

Long-Range π-Conjugation in Phenothiazine-containing Donor-Acceptor Dyes for Application in Dye-Sensitized Solar Cells

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Carole Graetzel, Jinhyun Kim, Thomas Moehl, Mateusz Barnaba Wielopolski, Yuxiang Yu

Four organic donor–π-bridge–acceptor dyes containing phenothiazine as a spacer and cyanoacrylic acid as an acceptor were synthesized and tested as sensitizers in dye-sensitized solar cells (DSCs). The influence of iodide- and cobalt-based redox electrolyte ...
