Scientists capture candid snapshots of electrons harvesting light at the atomic scale – Phys.org

In the search for clean energy alternatives to fossil fuels, one promising solution relies on photoelectrochemical (PEC) cellswater-splitting, artificial-photosynthesis devices that turn sunlight and water into solar fuels such as hydrogen.
In just a decade, researchers in the field have achieved great progress in the development of PEC systems made of light-absorbing gold nanoparticlestiny spheres just billionths of a meter in diameterattached to a semiconductor film of titanium dioxide nanopa…
