High-flux optical systems for solar thermochemistry

Sophia Haussener, Gaël Jean Clément Levêque

High-flux optical systems (HFOSs) are optical concentrators used to increase the radiative flux of the natural terrestrial solar irradiation. High radiative flux concentration leads to high energy density in solar receivers which allow to obtain high tempe ...

CuInGaS2 photocathodes treated with SbX3 (X = Cl, I): the effect of the halide on solar water splitting performance

Kevin Sivula, Nestor Guijarro Carratala, Florian Le Formal, Xavier Adrian Jeanbourquin, Xiaoyun Yu, Mathieu Steven Prévot, Pauline Bornoz, Wiktor Stefan Bourée

The realization of photoelectrochemical tandem cells for efficient solar-to-hydrogen energy conversion is currently impeded by the lack of inexpensive, stable, and efficient photocathodes. The family of sulfide chalcopyrites (CuInxGa1-xS2) has recently dem ...

Spectroelectrochemical analysis of the mechanism of (photo)electrochemical hydrogen evolution at a catalytic interface

Florian Le Formal, Matthew Thomas Mayer, Stanley David Tilley

Multi-electron heterogeneous catalysis is a pivotal element in the ( photo) electrochemical generation of solar fuels. However, mechanistic studies of these systems are difficult to elucidate by means of electrochemical methods alone. Here we report a spec ...
