Lead Iodide Perovskite Sensitized All-Solid-State Submicron Thin Film Mesoscopic Solar Cell with Efficiency Exceeding 9%

Michael Graetzel, Jacques-Edouard Moser, Jun Ho Yum, Arianna Marchioro, Robin Humphry-Baker, Thomas Moehl, Soo-Jin Moon, Jeong-Hyeok Im

We report on solid-state mesoscopic heterojunction solar cells employing nanoparticles (NPs) of methyl ammonium lead iodide (CH3NH3)PbI3 as light harvesters. The perovskite NPs were produced by reaction of methylammonium iodide with PbI2 and deposited onto ...

A cobalt complex redox shuttle for dye-sensitized solar cells with high open-circuit potentials

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jacques-Edouard Moser, Jun Ho Yum, Arianna Marchioro, Thomas Moehl, Chenyi Yi, Takeru Bessho, Elham Ghadiri

Dye-sensitized solar cells are a promising alternative to traditional inorganic semiconductor- based solar cells. Here we report an open-circuit voltage of over 1,000 mV in mesoscopic dye- sensitized solar cells incorporating a molecularly engineered cobal ...

Butyronitrile-based electrolyte for dye-sensitized solar cells

Michael Graetzel, Jacques-Edouard Moser, Arianna Marchioro, Sarine Chhor

We elaborated a new electrolyte composition, based on butyronitrile solvent, that exhibits low volatility for use in dye-sensitized solar cells. The strong point of this new class of electrolyte is that it combines high efficiency and excellent stability p ...

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 ...
