Energy from Sunlight: Further Steps towards Artificial Photosynthesis

[font size=5]Energy from Sunlight: Further Steps towards Artificial Photosynthesis[/font]
[font size=4]Chemists from the Universities of Basel and Zurich have come one step closer to generating energy from sunlight: for the first time, they were able to reproduce one of the crucial phases of natural photosynthesis with artificial molecules. Their results have been published by the journal Angewandte Chemie (international edition).[/font]
[font size=3]Green plants are able to temporarily store electric charges after the absorption of sunlight by using a so-called molecular charge accumulator. The two research teams were able to observe this process in artificial molecules that they created specifically for this experiment.[/font]
[font size=4]Two charges stored shortly[/font]
[font size=3][font size=3]The chemists excited the artificial molecules using a laser, which then made it possible to store two negative charges for a short time span for the very first time. They succeeded in storing the charges long enough, namely for 870 nanoseconds, thus making them effectively usable for artificial photosynthesis.
…
“Our results represent a fundamental and important step on the path to artificial photosynthesis”, say Prof. Oliver Wenger (University of Basel) and Prof. Peter Hamm (University of Zurich), who jointly led the study. However, they claim, it is still a long way to go until the aspired sustainable application will become reality.
