Singlet fission is a process in which one singlet exciton (an excited state of a molecule) splits into two triplet excitons. This phenomenon has garnered interest in the field of photovoltaics and organic electronics because it can potentially double the amount of charge carriers generated from a single photon, thus increasing the efficiency of solar cells. Researchers are investigating various organic materials and strategies to enhance the efficiency of singlet fission and its application in next-generation solar energy technologies.
