Liquid State and Zombie Dye Sensitized Solar Cells with Copper Bipyridine Complexes Functionalized with Alkoxy Groups

Michael Graetzel, Shaik Mohammed Zakeeruddin, Rosario Scopelliti, Jacques-Edouard Moser, Ulf Anders Hagfeldt, Joël Teuscher, Yasemin Saygili, Marina Freitag, Hui-Seon Kim, Marko Stojanovic

Copper redox mediators can be employed in dye sensitized solar cells (DSCs) both as liquid electrolytes or as solid state hole transport materials (HTMs). The solid state devices that employ copper complex HTMs can be simply obtained by solvent evaporation ...

Effect of Coordination Sphere Geometry of Copper Redox Mediators on Regeneration and Recombination Behavior in Dye-Sensitized Solar Cell Applications

Shaik Mohammed Zakeeruddin, Yasemin Saygili, Jacques-Edouard Moser, Ulf Anders Hagfeldt, Joël Teuscher, Fabrizio Giordano, Marina Freitag, Marko Stojanovic, Jan Tiepelt

The recombination of injected electrons with oxidized redox species and regeneration behavior of copper redox mediators are investigated for four copper complexes, [Cu(dmby)2]2+/1+ (dmby = 6,6′-dimethyl-2,2′- bipyridine), [Cu(tmby)2]2+/1+ (tmby = 4,4′,6,6′ ...

Inter-Domain Charge Transfer as a Rationale for Superior Photovoltaic Performances of Mixed Halide Lead Perovskites

Jacques-Edouard Moser, Joël Teuscher, Fabrizio Giordano, Marine Eva Fedora Bouduban, Eric Vauthey

Organic-inorganic lead halide perovskites containing a mixture of iodide and bromide anions consistently perform better in donor-acceptor heterojunction solar cells than the standard methylammonium lead triiodide material. This observation is counterintuit ...

Energy and Charge Transfer Cascade in Methylammonium Lead Bromide Perovskite Nanoparticle Aggregates

Jacques-Edouard Moser, Joël Teuscher, Marine Eva Fedora Bouduban, Andrés Burgos Caminal, Rachele Ossola

Highly photoluminescent hybrid lead halide perovskite nanoparticles have recently attracted a wide interest in the context of high-stake applications, such as light emitting diodes (LEDs), light emitting transistors and lasers. In addition, they constitute ...

Charge migration and charge transfer in molecular systems

Majed Chergui, Ursula Röthlisberger, Jacques-Edouard Moser, Andrea Cannizzo, Natalie Renuka Banerji, Joël Teuscher, Christopher Alexander Arrell, Pablo Lopez Tarifa, Elisa Liberatore

The transfer of charge at the molecular level plays a fundamental role in many areas of chemistry, physics, biology and materials science. Today, more than 60 years after the seminal work of R. A. Marcus, charge transfer is still a very active field of res ...

Unveiling the Nature of Charge Carrier Interactions by Electroabsorption Spectroscopy: An Illustration with Lead-Halide Perovskites

Jacques-Edouard Moser, Joël Teuscher, Marine Eva Fedora Bouduban, Andrés Burgos Caminal

Unravelling the nature of the interactions between photogenerated charge carriers in solar energy conversion devices is key to enhance performance. In this perspective, we discuss electroabsorption spectroscopy (EAS), as the spectral bandshape of the elect ...

Charge separation and carrier dynamics in donor-acceptor heterojunction photovoltaic systems

Majed Chergui, Ursula Röthlisberger, Jacques-Edouard Moser, Ariadni Boziki, Natalie Renuka Banerji, Joël Teuscher, Jan Cornelius Brauer, Alicia Solano, Jean-Pierre Wolf

Electron transfer and subsequent charge separation across donor-acceptor heterojunctions remain the most important areas of study in the field of third-generation photovoltaics. In this context, it is particularly important to unravel the dynamics of indiv ...

11% efficiency solid-state dye-sensitized solar cells with copper(II/I) hole transport materials

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Ulf Anders Hagfeldt, Jingshan Luo, Fabrizio Giordano, Joël Teuscher, Norman Pellet, Yiming Cao, Amita Ummadisingu, Yasemin Saygili

Solid-state dye-sensitized solar cells currently suffer from issues such as inadequate nanopore filling, low conductivity and crystallization of hole-transport materials infiltrated in the mesoscopic TiO2 scaffolds, leading to low performances. Here we rep ...
