Doubling the Excitons From a Photon of Light

August 20, 2019 | Leave a Comment

Columbia University scientists have designed organic molecules capable of generating two excitons per photon of light. The process is called singlet fission. Of importance is 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 […]

Singlet Fission in Solar Cells Gains Credence

July 10, 2014 | Leave a Comment

Scientists have reviewed chemists’ work on “singlet fission,” a process in which a single photon generates a pair of excited states. Singlet fission as a 1->2 conversion process has the potential to boost solar cell efficiency by as much as 30 percent. Chemists at the University of California, Riverside published a perspective article published last […]
