Materials that can revolutionize how light is harnessed for solar energy
19 Aug 2019 at 8:27am
Scientists have designed organic molecules capable of generating two excitons per photon of light, a process called singlet fission. The excitons can live for much longer than those generated from their inorganic counterparts, which leads to an amplification of electricity generated per photon that is absorbed by a solar cell.
