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 ...

Photoinduced Interfacial Electron Injection Dynamics in Dye-Sensitized Solar Cells under Photovoltaic Operating Conditions

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jean-David Décoppet, Joël Teuscher, Angela Punzi

We report a pump–probe spectroscopy study of electron injection rates in dye-sensitized solar cell (DSSC) devices. We examine the case of working devices employing an N719 ruthenium sensitizer and an iodide electrolyte. Electron injection is found to occur ...

Photoinduced interfacial electron transfer and lateral charge transport in molecular donor–acceptor photovoltaic systems

Jacques-Edouard Moser, Arianna Marchioro, Jan Cornelius Brauer, Elham Ghadiri, Jelissa Risse, Angela Punzi

Nanostructured liquid|solid and solid|solid bulk heterojunctions designed for the conversion of solar energy offer ideal models for the investigation of light-induced ET dynamics at surfaces. Despite significant study of processes leading to charge generat ...

Dynamics and mechanisms of interfacial photoinduced electron transfer processes of third generation photovoltaics and photocatalysis

Jacques-Edouard Moser, Arianna Marchioro, Christophe Bauer, Natalie Renuka Banerji, Joël Teuscher, Jan Cornelius Brauer, Mateusz Barnaba Wielopolski, Elham Ghadiri, Jelissa Risse, Angela Punzi

Photoinduced electron transfer (PET) across molecular/bulk interfaces has gained attention only recently and is still poorly understood. These interfaces offer an excellent case study, pertinent to a variety of photovoltaic systems, photo- and electrochemi ...
