\"Excitons<\/p>\n

W<\/span>hen light is absorbed in organic materials, its energy is converted into excitons (electronic excitations) that normally move around by \u201chopping\u201d from molecule to molecule. This is important in photosynthesis or solar cells, for example. There, the energy of the absorbed sunlight has to be brought to a \u201creaction center\u201d, where it can be used to power chemical or electrical\u00a0processes.<\/p>\n

In many organic materials, energy transport is inefficient because of the large amount of disorder and motion of the molecules. The theoretical work, carried out by IFIMAC<\/span> researchers Johannes Feist and Francisco J. Garcia-Vidal, shows that an extraordinary increase of the transportation efficiency (or \u201cexciton conductance\u201d) can be achieved by placing two mirrors on both sides of the organic material. The excitons can then not only hop from molecule to molecule, but also transfer their energy back into light trapped between the mirrors. When this happens quickly enough, the exciton and light behave as an effective new particle with hybrid properties borrowed from both constituents. In this regime of \u201cstrong coupling\u201d, energy transferred into the system at one spot can efficiently \u201cjump\u201d over a large distance, bypassing the disordered collection of molecules.
