Breakthrough light-harvesting photoswitch can store solar power for months | When heat is stored as chemical bonds, it can be retained for weeks and months without energy losses.
Photoswitches were developed a few years ago but needed to be activated by UV light. New research removes this requirement and makes them more efficient.
“The sensitizer absorbs light and subsequently transfers energy to the photoswitch, which cannot be directly excited under these conditions,” explained Christoph Kerzig, a professor of inorganic chemistry at JGU, in a press release.

Till Zähringer, a PhD student in Kerzig’s lab, played an important role in the study, explored the system in great detail, and helped achieve more than harvesting with indirect light.
