Silicon protected with atomic layer deposited TiO2: durability studies of photocathodic H-2 evolution

The semiconducting materials used for photoelectrochemical (PEC) water splitting must withstand the corrosive nature of the aqueous electrolyte over long time scales in order to be a viable option for large scale solar energy conversion. Here we demonstrat ...

On the Texturing and Nanostructuring of Iron Oxide Photoanodes for Solar Water Splitting

Maurin Cornuz

The world needs to think about the after fossil fuel era and while the sun baths the earth with a tremendous amount of energy, man must learn how to harvest and store it in order to dispose of a continuous supply meeting his needs. Water photo-electrolysis ...

Optimal Design of Solar Assisted Hydrothermal Gasification for Microalgae to Synthetic Natural Gas Conversion

François Maréchal, Adriano Viana Ensinas, Alberto Mian, Gianluca Ambrosetti

Catalytic hydrothermal gasification is a promising technology which allows the conversion of wet biomass into methane rich syngas. It consists of three major steps, in which thermal energy has to be supplied at different temperature levels, leading to mult ...

Efficiency of a micro-bubble reflector based, self-adaptive waveguide solar concentrator

Eric Tremblay, Volker Günter Zagolla

State of the art solar concentrators use free-space, non-imaging optics to concentrate sunlight. Mechanical actuators keep the focal spot on a small solar cell by tracking the sun's position. Planar concentrators emerged recently that employ a waveguide sl ...
