Solar fuels: better efficiency using microwires on Science stuff

Jan. 15, 2018, 7:08 p.m.

Researchers have made significant efficiency improvements to the technology used to generate solar fuels. This involves the direct conversion of energy from sunlight into a usable fuel (in this case, hydrogen). Using only earth-abundant materials, they developed the most efficient conversion method to date. The trick was to decouple the site where sunlight is captured from the site where the conversion reaction takes place.https://www.sciencedaily.com/releases/2018/01/180115121641.htm
