Transparent Porous Conductive Substrates for Gas-Phase Photoelectrochemical Hydrogen Production

Kevin Sivula, Jun Ho Yum, Simon Nussbaum, Rebekah Anne Wells, Marina Caroline Michèle Caretti, Hannah Elizabeth Johnson, Emeline Cécile Rideau, Benjamin Goldman, Elizaveta Potapova Mensi

Gas diffusion electrodes are essential components of common fuel and electrolysis cells but are typically made from graphitic carbon or metallic materials, which do not allow light transmittance and thus limit the development of gas-phase based photoelectr ...

Long‐Lived Photocharges in Supramoelcular Polymers of Low‐Bandgap Chromophores

Andrzej Sienkiewicz, Holger Frauenrath, Daniel Görl, Regina Judith Hafner

Photoinduced charge separation in supramolecular aggregates of π‐conjugated molecules is a fundamental photophysical process, and a key criterion for the development of advanced organic electronics materials. Here, we report on the self‐assembly of novel l ...

CuSCN as Hole Transport Material with 3D/2D Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Iwan Zimmermann

We report stable perovskite solar cells having 3D/2D perovskite absorber layers and CuSCN as an inorganic hole transporting material (HTM). (Phenylethyl)ammonium (PEA) and [(4-fluorophenyl)ethyl]ammonium (FPEA) have been chosen as 2D cations, creating thin ...

Experiments and modelling for glow discharge plasmas applied to niobium sputter deposition in superconducting radiofrequency cavities

Thibaut François Hugo Richard

Thin film coatings are ubiquitous in modern daily lives, from the semi-conductor industry to aesthetic applications, and rely on the modification of a given material to enhance its surface properties. At CERN (European Organization for Nuclear Research), t ...

Layer transfer of epitaxial layers and thin films obtained by van der waals growth initiation

Anna Fontcuberta i Morral, Rajrupa Paul, Andrea Giunto

A thin film grown on a substrate to which the attractive forces are of lower strength than covalent, metallic and/or ionic bonds can be detached from the substrate without the need of a Smart-cut type of process, e.g. without the need of ion implantation. ...

Improved Nonaqueous Synthesis of TiO2 for Dye-Sensitized Solar Cells

Michael Graetzel, Morgan Mertens Stefik, Markus Niederberger

Nonaqueous synthesis routes have emerged as a powerful platform for directly obtaining diverse metal oxide nanoparticles with high crystallinity and tunable compositions. The benzyl alcohol (BA) route, for example, has been applied toward dozens of oxides ...

Correlating long-lived photogenerated hole populations with photocurrent densities in hematite water oxidation photoanodes

Michael Graetzel, Kevin Sivula

Photogenerated charge carrier dynamics are investigated as a function of applied bias in a variety of different hematite photoanodes for solar water oxidation. Transient absorption spectroscopy is used to probe the photogenerated holes, while transient pho ...
