Smoothening intermediate reflecting layer for tandem thin-film silicon solar cells

Christophe Ballif, Corsin Battaglia, Nicolas Blondiaux, Matthieu Despeisse, Mathieu Gérard Boccard

We introduce the concept of smoothening intermediate reflecting layers (IRLs) in Micromorph thin-film silicon tandem solar cells in the superstrate configuration. The aim of such structures is not only to provide a selective reflection of light for optimal ...

A selective chemiluminescence detection method for reactive oxygen species involved in oxygen reduction reaction on electrocatalytic materials

Christos Comninellis, Pauline Bornoz

An original selective and quantitative detection method for direct access to reactive oxygen species (ROS) generated in near-neutral aqueous solutions during transient electrochemical experiments is described herein. Several chemiluminescent probes, which ...

Flow patterns induced by a bubble screen in a sharply curved flume based on Acoustic Doppler Velocity Profiler measurements

Anton Schleiss, Koen Blanckaert, Violaine Dugué

Open-channel bends are characterized by a bed morphology where erosion occurs near the outer bank and a point bar develops at the inner bend. This morphology is induced by complex interactions between the streamwise flow, the curvature-induced secondary fl ...

Segmented Field OFFGEL® Electrophoresis

Hubert Girault, Julien Maillard, Fernando Cortes Salazar, Dmitry Momotenko, Elena Tobolkina

A multielectrode setup for protein OFFGEL electrophoresis that significantly improves protein separation efficiency has been developed. Here, the electric field is applied by segments between seven electrodes connected in series to six independent power su ...

Characterization of a novel impedance cytometer design and its integration with lateral focusing by dielectrophoresis

Philippe Renaud, Enri Duqi

This paper reports a novel impedance cytometer design, easily integrable with dielectrophoretic focusing using a simple fabrication process with a single metal layer. Patterning of electrodes recessed in lateral channels – so-called “liquid electrodes” – a ...

Chromium Poisoning

Josef Andreas Schuler

This thesis focuses on Cr-poisoning in solid oxide fuel cells (SOFC), which currently presents a key challenge for the development of this technology. By the implementation of dedicated experimental tools, this work offers a new access to, and comprehensio ...

Optimization of ZnO Front Electrodes for High-Efficiency Micromorph Thin-Film Si Solar Cells

Christophe Ballif, Corsin Battaglia, Matthieu Despeisse, Mathieu Gérard Boccard, Sylvain Nicolay, Grégory Bugnon, Laura Ding, Thomas Söderström, Peter Cuony, Simon Hänni, Adrian Billet, Mathieu Charrière, Mustapha Benkhaira

The quest for increased performances in thin film silicon Micromorph tandem devices nowadays requires an increase of current density. This can be achieved with thin cells by combining both a robust cell design and efficient light management schemes. In thi ...

Novel Micromorph Solar Cell Structures for Efficient Light Trapping and High-Quality Absorber Layers

Mathieu Gérard Boccard

Key elements involved in the fabrication of Micromorph thin-film silicon solar cells, a tandem device including an amorphous silicon top cell and a microcrystalline silicon bottom cell, are studied in this manuscript. Due to the very short diffusion length ...

Compilation of mechanical properties for the structural analysis of solid oxide fuel cell stacks. Constitutive materials of anode-supported cells

Jan Van Herle, Antonin Faes, Arata Nakajo

The mechanical failure of one cell is sufficient to lead to the end of service of a solid oxide fuel cell (SOFC) stack. Therefore, there is growing interest in gaining knowledge on the mechanical properties of the cell materials for stress analysis. This s ...

RedOx Stability of Anode Supported Solid Oxide Fuel Cells

Antonin Faes

The weakness of nickel-based solid oxide fuel cell anodes is their low ability to withstand re-oxidation at working temperature, especially for the anode-supported cell design. The volume expansion coming along with nickel (Ni) oxidation induces stresses i ...
