Scientists lay out plans for efficient harvesting of solar energy
Date:9/23/2011

Solar power could be harvested more efficiently and transported over long distances using tiny molecular circuits, according to research inspired by new insights into natural photosynthesis.

Incorporating the latest research into how plants, algae and some bacteria use quantum mechanics to optimise energy production via photosynthesis, scientists have set out how to design molecular "circuitry" that is 10 times smaller than the thinnest electrical wire in computer processors. Published in Nature Chemistry, the report discusses how tiny molecular energy grids could capture, direct, regulate and amplify raw solar energy.

Professor Gregory Scholes, lead author from the University of Toronto said: "Solar fuel production often starts with the energy from light being absorbed by an assembly of molecules. The energy is stored fleetingly as vibrating electrons and then transferred to a suitable reactor.

"It is the same in biological systems. In photosynthesis, for example, antenna complexes comprised of chlorophyll capture sunlight and direct the energy to special proteins that help make oxygen and sugars. It is like plugging those proteins (called reaction centres) into a solar power socket."

In natural systems energy from sunlight is captured by 'coloured' molecules called dyes or pigments, but is only stored for a billionth of a second. This leaves little time to route the energy from pigments to the molecular machinery that produces fuel or electricity.

The key to transferring and storing energy very quickly is to harness the collective quantum properties of antennae, which are made up of just a few tens of pigments.

Dr Alexadra Olaya-Castro, co-author of the paper from UCL's department of Physics and Astronomy said: "On a bright sunny day, more than 100 million billion red and blue "coloured" photons strike a leaf each second.

"Under these conditions plants need to be able to both use t
