Control and Study of the Stoichiometry in Evaporated Perovskite Solar Cells

Michael Graetzel, Joël Teuscher, Nicolas Tétreault

Herein, we present the precise stoichiometric control of methlyammonium lead iodide perovskite thin-films using high vacuum dual-source vapor-phase deposition. We found that UV/Vis absorption and emission spectra were inadequate for assessing precisely the ...

High-Efficiency Solid-State Dye-Sensitized Solar Cells: Fast Charge Extraction through Self-Assembled 3D Fibrous Network of Crystalline TiO2 Nanowires

Michael Graetzel, Shaik Mohammed Zakeeruddin, László Forró, Arnaud Magrez, Endre Horvath, Nicolas Tétreault, Peng Wang, Thomas Moehl, Rita Smajda, Laurent Gabriel Félix Alexandre Stéphane Bungener, Jérémie Minh-Châu Brillet

Herein, we present a novel morphology for solid-state dye-sensitized solar cells based on the simple and straightforward self-assembly of nanorods into a 3D fibrous network of fused single-crystalline anatase nanowires. This architecture offers a high roug ...

Yttrium-substituted nanocrystalline TiO2 photoanodes for perovskite based heterojunction solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Peng Gao, Mohammad Ibrahim Dar, Thomas Moehl, Peng Gao, Aravind Kumar Chandiran, Nicolas Tétreault, Peng Qin

We report the use of Y3+-substituted TiO2 (0.5% Y-TiO2) in solid-state mesoscopic solar cells, consisting of CH3NH3PbI3 as the light harvester and spiro-OMeTAD as the hole transport material. A power conversion efficiency of 11.2% under simulated AM 1.5 fu ...

Improved electrode

Michael Graetzel, Nicolas Tétreault, Jérémie Minh-Châu Brillet

The present invention provides a generic electrode for photovoltaics, water splitting cells or any electro-chemical device where a three-dimensional transparent conductive backbone provides efficient charge extraction and can support an active guest materi ...

Passivation of ZnO Nanowire Guests and 3D Inverse Opal Host Photoanodes for Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Thomas Moehl, Aravind Kumar Chandiran, Nicolas Tétreault, Hauke Arne Harms, Philippe Pierre Labouchère

A hierarchical host-guest nanostructured photoanode is reported for dye-sensitized solar cells. It is composed of ZnO nanowires grown in situ into the macropores of a 3D ZnO inverse opal structure, which acts both as a seed layer and as a conductive backbo ...
