Sentences with phrase «dot photoelectrochemical»

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 %.

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.
