Dynamics of Photoinduced Interfacial Electron Transfer and Charge Transport in Dye-Sensitized Mesoscopic Semiconductors

Jacques-Edouard Moser, Christophe Bauer, Joël Teuscher, Bernard Wenger, Verner Thorsmolle

Molecular systems designed for the conversion of solar energy offer ideal models in the study of the kinetics of light-induced electron transfer at surfaces. Due to their high porosity, nanocrystalline oxide semiconductor films allow investigations of inte ...

Electron donor-acceptor distance dependence of the dynamics of light-induced interfacial charge transfer in the dye-sensitization of nanocrystalline oxide semiconductors

Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Christophe Bauer, Pascal Comte, Bernard Wenger

The effect of electronic and nuclear factors on the dynamics of dye-to-semiconductor electron transfer was studied employing RuII(terpy)(NCS)3 sensitizers grafted onto transparent films made of titanium dioxide nanoparticles. Various approaches were strive ...

Hot Adsorbate-Induced Retardation of the Internal Thermalization of Nonequilibrium Electrons in Adsorbate-Covered Metal Nanoparticles

Hubert Girault, Christophe Bauer, Jean-Pierre Abid

Femtosecond transient absorption spectroscopy has been used to investigate the electron-electron scattering dynamics in sulfate-covered gold nanoparticles of 2.5 and 9.2 nm in diameter. We observe an unexpected retardation of the absolute internal thermali ...

Role of Adsorbates on Dynamics of Hot-Electron (type I and II) Thermalization within Gold Nanoparticles

Hubert Girault, Christophe Bauer, Jean-Pierre Abid

Early stages of hot-electron thermalization in small gold nanoparticles wrapped in an adsorbates shell have been investigated by femtosecond transient absorption spectroscopy. Type-I hot electrons thermalize in 800 fs (to form type-II hot electron) either ...

Size Dependence of Investigations of Hot Electron Cooling Dynamincs in Metal/Adsorbates Nanoparticles

Hubert Girault, Christophe Bauer, Jean-Pierre Abid

The size dependence of electron-phonon coupling rate has been investigated by femtosecond transient absorption spectroscopy for gold nanoparticles (NPs) wrapped in a shell of sulfate with diameter varying from 1.7 to 9.2 nm. Broad-band spectroscopy gives a ...

Ultrafast relaxation dynamics of charge carriers in ZnO nanocrystalline thin films

Ulf Anders Hagfeldt, Christophe Bauer

Ultrafast spectroscopy was used to study the relaxation processes of charge carriers in ZnO nanocryst. thin films. A broad red-IR absorption band linked to shallowly trapped electrons was obsd. by spectroelectrochem. measurements. Femtosecond transient abs ...

Interfacial Electron-Transfer Dynamics in Ru(tcterpy)(NCS)3-Sensitized TiO2 Nanocrystalline Solar Cells

Ulf Anders Hagfeldt, Christophe Bauer

The anchoring of the ruthenium dye {(C4H9)4N}[Ru(Htcterpy)(NCS)3] (tcterpy = 4,4',4''-tricarboxy-2,2':6',2''-terpyridine), the so-called black dye, onto nanocryst. TiO2 films has been characterized by UV-visible and FTIR spectroscopies. FTIR spectroscopy d ...

Nanostructured ZnO electrodes for dye-sensitized solar cell applications

Ulf Anders Hagfeldt, Christophe Bauer

Dye-sensitized photoelectrochem. solar cells constitute a promising candidate in the search for cost-effective and environment-friendly solar cells. The most extensively studied, and to date the most efficient systems are based on titanium dioxide. In this ...

Ultrafast studies of electron injection in Ru dye sensitized SnO2 nanocrystalline thin film

Ulf Anders Hagfeldt, Christophe Bauer

The electron injection rate of bis(Bu4N) cis di(thiocyanato) bis (2,2'-bypiridine-4,4' carboxylic acid)Ruthenium (II) dye (N719) into SnO2 nanocryst. thin films was measured with 2-color femtosecond transient absorption spectroscopy. The electron injection ...
