Dynamics of Interfacial Electron Transfer from Betanin to Nanocrystalline TiO2: The Pursuit of Two-Electron Injection

Jacques-Edouard Moser, Arianna Marchioro

We report spectroelectrochemical and transient absorption spectroscopic studies of electron injection from the plant pigment betanin (Bt) to nanocrystalline TiO2. Spectroelectrochemical experiments and density functional theory (DFT) calculations are used ...

Kinetics of the Regeneration by Iodide of Dye Sensitizers Adsorbed on Mesoporous Titania

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Arianna Marchioro, Julien Alexandre Andres, Peng Wang, Joël Teuscher

Regeneration of dye sensitizer molecules by reducing species contained in the electrolyte is a key mechanism in liquid dye-sensitized solar cells because it competes kinetically with a detrimental charge recombination process. Kinetics of the reduction by ...

Two-electron photo-oxidation of betanin on titanium dioxide and potential for improved dye-sensitized solar energy conversion

Jacques-Edouard Moser, Arianna Marchioro

The plant pigment betanin is investigated as a dye-sensitizer on TiO2 with regard to its potential to undergo two- electron oxidation following one-photon excitation. Electrochemical, spectroelectrochemical and transient absorption measurements provide evi ...

Unravelling the mechanism of photoinduced charge transfer processes in lead iodide perovskite solar cells

Michael Graetzel, Jacques-Edouard Moser, Arianna Marchioro, Thomas Moehl, Joël Teuscher

Lead halide perovskites have recently been used as light absorbers in hybrid organic–inorganic solid-state solar cells, with efficiencies as high as 15% and open-circuit voltages of 1 V. However, a detailed explanation of the mechanisms of operation within ...

Effect of Posttreatment of Titania Mesoscopic Films by TiCl4 in Solid- State Dye-Sensitized Solar Cells: A Time-Resolved Spectroscopy Study

Michael Graetzel, Jacques-Edouard Moser, Arianna Marchioro, Amalie Dualeh, Angela Punzi

Post-treatment of mesoporous titanium dioxide films by TiCl4 solutions is commonly applied during the fabrication of solid-state dye-sensitized solar cells (ssDSCs), as this operation markedly improves the performance of the photovoltaic device. The effect ...
