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 ...

Laser arrival measurement tools for SwissFEL

Christoph Peter Hauri

SwissFEL is aiming to produce X-ray pulses from 30 fs down to the attosecond time scale. This requires the compression of the several picosecond long electron bunches produced by a photo-injector to sub-fs level. To achieve this, 40fs accurate injection of ...

Ultrafast charge transfer in solid-state films of pristine cyanine borate and blends with fullerene

Jacques-Edouard Moser, Frank Nüesch, Jakob Heier, Jelissa Risse

Photoinduced electron transfer in light-absorbing materials is the first step towards charge separation and extraction in small molecule-based organic solar cells. The excited state dynamics of the cyanine dye cation Cy3 paired with a tetraphenylborate cou ...

Picosecond solvation dynamics of alkali cations in superfluid 4He nanodroplets

Marcel Drabbels, Alberto Hernando de Castro

The dynamics following the photoionization of neutral Rb and Cs atoms residing in a dimple at the surface of a superfluid 4He1000 nanodroplet has been investigated within time-dependent density functional theory, complementing a previous study on Ba. The c ...

A Novel Collective Autoionization Process Observed in Electron Spectra of He Clusters

Marcel Drabbels, Nils Benedict Brauer

The ionization dynamics of He nanodroplets irradiated with intense femtosecond XUV pulses of up to 10^13 W/cm2 power density has been investigated by photoelectron spectroscopy. Helium droplets were resonantly excited to atomic-like 2p states with a photon ...

Ultrafast Dynamics of Massive Dirac Fermions in Bilayer Graphene

Marco Grioni, Alberto Crepaldi, Jens Christian Johannsen

Bilayer graphene is a highly promising material for electronic and optoelectronic applications since it is supporting massive Dirac fermions with a tunable band gap. However, no consistent picture of the gap's effect on the optical and transport behavior h ...

A System for Conducting Surface Science with Attosecond Pulses

Christopher Alexander Arrell

We report the development of an apparatus to allow time resolved photoelectron spectroscopy of charge motion on solids and structured surfaces with attosecond resolution in an ultra high vacuum environment. The system, connected to the Attosecond Beamline ...

Invited Review Article: Technology for Attosecond Science

Christopher Alexander Arrell

We describe a complete technological system at Imperial College London for Attosecond Science studies. The system comprises a few-cycle, carrier envelope phase stabilized laser source which delivers sub 4 fs pulses to a vibration-isolated attosecond vacuum ...

Can Energetic Terahertz Pulses Initiate Surface Catalytic Reactions on the Picosecond Time Scale?

Christoph Peter Hauri

In preparation for picosecond pump-probe experiments at the SwissFEL X-ray laser facility, the feasibility of collectively initiating surface chemical reactions using energetic pulses of terahertz radiation is being tested. © Schweizerische Chemische Gesel ...
