Quantum fission control

Singlet fission in organic molecules takes place in real time and could be exploited to create highly efficient solar cells, according to an international team led by scientists at the University of Cambridge. The team used ultrafast laser pulses to observe how a single particle of light, or photon, can be converted into two energetically excited particles, known as spin-triplet excitons, through a process called singlet fission. If singlet fission can be controlled, it could enable solar cells to double the amount of electrical current that can be extracted.
