Sentences with phrase «as photoelectrochemical»

After moving to Lawrence Livermore National Laboratory, he has been working on scientific problems that are relevant for energy storage and conversion technologies such as photoelectrochemical (PEC) hydrogen production.

The technologies include advanced high - and low - temperature electrolysis as well as photoelectrochemical (PEC) and solar thermochemical (STCH) water splitting.

Not exact matches

Nonetheless, this dramatic increase in quantum yield realized with a uniquely innovative lead sulfide quantum dot photoelectrochemical device is an important development in several ways, and as such is a product of Yan's long - standing interest in renewable sources of energy, especially in novel applications of solar energy.

Essentially, they created what is known as a quantum dot photoelectrochemical cell that catalytically achieved quantum efficiency for hydrogen gas production exceeding 100 % — in the case of their experiments an efficiency approaching 114 %.

Throughout the course of this study, the teams compiled an extensive library of experimental and theoretical data including electronic, magnetic, optical, photoelectrochemical, and structural properties, which are now used as feedstock in material genome work and near - term development of superior PEC materials through materials - by - design techniques.

However, as yet it has not been applied directly to photoelectrochemical cells.

The authors first present the analytic equations and solutions for the limiting efficiencies of photoelectrochemical water - splitting devices based on the ultimate limits of device physics as well as two more realistic scenarios based on currently achievable material and device parameters.
