Scientists augment artificial photosynthesis with more efficient light absorbers

Scientists from Japan have harvested solar energy using an exceptionally large number of light absorbers to relay photons via antennas into one final energy acceptor. This two-step sequence closely mimics natural photosynthesis, resulting in greater and more efficient energy transfer.

Previously, researchers had only used one-step light harvesting systems, greatly limiting the number of absorbers able to feed light into a single reaction centre. Now, by imitating photosynthetic systems,Osamu Ishitani at the Tokyo Institute of Technology, Shinji Inagaki at the Japan Science and Technology Agency and their co-workers have efficiently harvested light using the highest number of artificial leaves to date.
