Modelling of Solar Thermochemical Reaction Systems
This article reviews the progress, challenges and opportunities in numerical modelling of thermal transport, thermochemical reactions and thermomechanics in high-temperature solar thermochemical systems. Continuum-scale models are presented in mathematical ...
Pergamon-Elsevier Science Ltd2017High-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 ...
2017Minimization of Ionic Transport Resistance in Porous Monoliths for Application in Integrated Solar Water Splitting Devices
Monolithic solar water splitting devices consist of photovoltaic materials integrated with electrocatalysts and produce solar hydrogen by water splitting upon solar illumination in one device. Upscaling of monolithic solar water splitting devices is obstru ...
American Chemical Society2016Fabrication and Characterization of Functional ALD Metal Oxide Thin Films for Solar Applications
Motivated to revolutionize our today's fossil fuels based energy production, my work concentrated on the investigation of promising low-cost materials for photoelectrochemical hydrogen production and photovoltaic electricity generation. Hydrogen presents a ...
EPFL2016Integrated Photo-Electrochemical Solar Fuel Generators Under Concentrated Irradiation- Part II: Thermal Management a Crucial Design Consideration
Sophia Haussener, Saurabh Yuvraj Tembhurne
Concentrating solar irradiation for use in integrated photo-electrochemical devices potentially provides an economically competitive pathway for hydrogen generation, even with partial use of rare material components. Heat transfer and thermal management ar ...
Electrochemical Soc Inc2016Coupling of electrocatalysts to photoabsorbers for solar fuels production
The direct transformation of sunlight into fuels and chemicals has attracted considerable attention for the potential impact on the storage of solar energies at large scales and the reduction of CO2 emissions. More than 80% of our current global energy con ...
EPFL2016Solar-to-Hydrogen Production at 14.2% Efficiency with Silicon Photovoltaics and Earth-Abundant Electrocatalysts
Christophe Ballif, Demetri Psaltis, Christophe Moser, Antonin Faes, Jan-Willem Alexander Schüttauf, Matthieu Despeisse, Julien Claude Bailat, Miguel Antonio Modestino, Enrico Chinello, Antonio Delfino, David Lambelet
Affordable, stable and earth-abundant photo-electrochemical materials are indispensable for the large-scale implementation of sunlight-driven hydrogen production. Here we present an intrinsically stable and scalable solar water splitting device that is ful ...
Electrochemical Society2016Mass transport aspects of electrochemical solar-hydrogen generation
Sophia Haussener, Miguel Antonio Modestino, Seyyed Mohammad Hosseini Hashemi
The conception of practical solar-hydrogen generators requires the implementation of engineering design principles that allow photo-electrochemical material systems to operate efficiently, continuously and stably over their lifetime. At the heart of these ...
Royal Soc Chemistry2016Round-the-clock power supply and a sustainable economy via synergistic integration of solar thermal power and hydrogen processes
François Maréchal, Rakesh Agrawal
We introduce a paradigm-"hydricity"-that involves the coproduction of hydrogen and electricity from solar thermal energy and their judicious use to enable a sustainable economy. We identify and implement synergistic integrations while improving each of the ...
2015Efficient photosynthesis of carbon monoxide from CO2 using perovskite photovoltaics
Michael Graetzel, Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Jingshan Luo, Antonio Abate, Matthew Thomas Mayer, Marcel Roland Schreier, Ludmilla Steier
Artificial photosynthesis, mimicking nature in its efforts to store solar energy, has received considerable attention from the research community. Most of these attempts target the production of H-2 as a fuel and our group recently demonstrated solar-to-hy ...
