Effect of Operating Conditions on the Degradation of BiVO4 Photoanodes

Paul Feurstein, Sophia Haussener, Isaac Thomas Holmes-Gentle, Franky Esteban Bedoya Lora

This work investigates how irradiance, temperature, and electrolyte properties (pH, concentration, and flow rate), influence the degradation of spray-pyrolyzed BiVO4 photoanodes during water splitting for solar fuel production. A novel four-cell photoelect ...

Boron-emitter development for TOPCon c-Si solar cells based on plasma-deposited boron diffusion source and poly-Si(n) passivating contact

Thibault Schaller, Ludovica Lunghi, Christophe Ballif, Franz-Josef Haug, Julien Hurni, Ezgi Genç

The n-type TOPCon technology is currently the leading approach in the industry. Generally, it involves two high-temperature steps that can result in long cycle times and expensive processes. In this context, we propose a lean manufacturing process based on ...

Suppressing surface and interface recombination to afford efficient and stable inverted perovskite solar cells

Yong Ding, Yen-Cheng Liu

The top surface of the perovskite layer and the interface with the electron transporting layer play a key role in influencing the performance and operational stability of inverted perovskite solar cells (PSCs). A deficient or ineffective surface passivatio ...

A Universal Perovskite/C60 Interface Modification via Atomic Layer Deposited Aluminum Oxide for Perovskite Solar Cells and Perovskite-Silicon Tandems

Christophe Ballif, Aïcha Hessler-Wyser, Mounir Driss Mensi, Christian Michael Wolff, Kerem Artuk, Mostafa Rabie Shlaly Bahr Othman, Deniz Türkay

The primary performance limitation in inverted perovskite-based solar cells is the interface between the fullerene-based electron transport layers and the perovskite. Atomic layer deposited thin aluminum oxide (AlOX) interlayers that reduce nonradiative re ...

Hydrogen Diffusion in Hybrid Perovskites from Exchange NMR

David Lyndon Emsley, Aditya Mishra

Ion migration is an important phenomenon affecting the performance of hybrid perovskite solar cells. It is particularly challenging, however, to disentangle the contribution of H+ diffusion from that of other ions, and the atomic-scale mechanism remains un ...

Evaporating water-cooled methanation reactor for solid-oxide stack-based power-to-methane systems: Design, experiment and modeling

Jan Van Herle, Philippe Aubin

The power-to-methane process using a solid-oxide electrolyser, followed by an exothermic methanation reactor, is effective for the production of an energy carrier (synthesis methane) that can be readily stored and transported at a large scale. A significan ...

Large-scale benchmarks of the time-warp/graph-theoretical kinetic Monte Carlo approach for distributed on-lattice simulations of catalytic kinetics

Giannis Savva

Motivated by the need to perform large-scale kinetic Monte Carlo (KMC) simulations, in the context of unravelling complex phenomena such as catalyst reconstruction and pattern formation, we extend the work of Ravipati et al. [S. Ravipati, G. D. Savva, I.-A ...
