Man-made ‘leaves’ mimic photosynthesis

Researchers have created leaves that harvest light much like plants do, enabling them to harness energy from the sun.

The team from the Tokyo Institute of Technology and Toyota Central R&D Labs, Inc. followed the two-step process of photosynthesis in which plants absorb photons from sunlight and then use them in a reaction process to produce sugars for food.

The researchers built 440 “leaves” to absorb light and relay energy through a metal system to feed an energy acceptor.  The team was able to create a strong light powered by photonic energy.  This technology can be used to build better photocatalysts and produce more efficient light.
