A High-Voltage Aqueous Electrolyte for Sodium-Ion Batteries

Corsin Battaglia, David Reber

Sodium bis(fluorosulfonyl)imide based aqueous electrolytes exhibit a wide electrochemical stability window of up to 2.6 V when the water-to-salt molar ratio falls below 2:1, enabling the fabrication of high-voltage rechargeable aqueous sodium-ion batteries ...

A Nearly Zero-Strain Li-Rich Rock-Salt Oxide with Multielectron Redox Reactions as a Cathode for Li-Ion Batteries

Corsin Battaglia, Chunyang Zhang, Xiao Liu

Li-rich oxide cathodes are drawing increasing attention as next-generation cathode materials for the development of high-energy-density Li-ion batteries due to their strikingly high capacities. However, transition-metal migration, irreversible structural p ...

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

Christophe Ballif, Matthieu Despeisse, Corsin Battaglia, 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 ...

Geometric light trapping for high efficiency thin film silicon solar cells

Christophe Ballif, Franz-Josef Haug, Matthieu Despeisse, Grégory Bugnon, Corsin Battaglia, Sylvain Nicolay, Jordi Escarre Palou, Laura Ding

The imprinting of random square based pyramidal textures with micrometric scale at the air/glass interface of thin film silicon solar cells is presented as an efficient alternative to anti-reflective coatings to minimize reflection losses at the cell entra ...

The Origin of the Catalytic Activity of a Metal Hydride in CO2 Reduction

Andreas Züttel, Corsin Battaglia, Shunsuke Kato

Atomic hydrogen on the surface of a metal with high hydrogen solubility is of particular interest for the hydrogenation of carbon dioxide. In a mixture of hydrogen and carbon dioxide, methane was markedly formed on the metal hydride ZrCoHx in the course of ...

UV imprinting for thin film solar cell application

Christophe Ballif, Franz-Josef Haug, Corsin Battaglia, Jordi Escarre Palou, Céline Pahud, Rémi Biron

UV imprinting is an interesting, low cost technique to produce large area thin film solar cells incorporating nanometric textures. Here, we review and present new results confirming that replicas of the most common textures used in photovoltaics can be obt ...

Amorphous Si Thin Film Based Photocathodes with High Photovoltage for Efficient Hydrogen Production

Christophe Ballif, Mathieu Gérard Boccard, Corsin Battaglia

An amorphous Si thin film with TiO2 encapsulation layer is demonstrated as a highly promising and stable photocathode for solar hydrogen production. With platinum as prototypical cocatalyst, a photocurrent onset potential of 0.93 V vs RHE and saturation ph ...

(Bi)carbonate Precipitation and Gas Diffusion Electrode Stability Coexist during Pulsed Electrochemical CO2 Reduction

Corsin Battaglia

Pulsed electrolysis is an effective strategy to stabilize the high selectivity of Cu gas diffusion electrodes toward C >= 2 products, the decrease of which over time under continuous operation is often ascribed to (bi)carbonate precipitation. Here, we demo ...

High fidelity transfer of nanometric random textures by UV embossing for thin film solar cells applications

Christophe Ballif, Franz-Josef Haug, Corsin Battaglia, Jordi Escarre Palou, Karin Söderström

We investigate the transfer of random nanostructures commonly used in thin film silicon solar cells onto inexpensive substrates, such as glass or flexible polyethylene sheets. Morphological and optical analyses of masters and replicas show the successful t ...

9.4% Efficient Amorphous Silicon Solar Cell on High Aspect-Ratio Glass Microcones

Christophe Ballif, Corsin Battaglia

High aspect-ratio three-dimensional (3D) a-Si:H solar cells have been fabricated to enhance a light absorption path while maintaining a short carrier collection length. Substantial efficiency enhancement in 3D solar cells was achieved due to the boost in J ...
