Abstract
Silicon solar cells are approaching their efficiency limit of 29% under the standard solar spectrum. In order to surpass this limit, a device is required that better manages the energy in each incoming energy packet (photon). One approach to this end is to split the energy of higher energy photons in two, such that two electron-hole pairs can be generated by one photon. This strategy has an upper limit of 45.9%. Organic Multiple Exciton Generation (OMEG) is executed by a photophysical process called singlet fission. A spin-0 (singlet) exciton is generated by a photon, and it decays into two spin-1 triplet excitons in a spin-conserving process. This talk will detail our progress towards developing OMEG augmented silicon solar cells (OMEGA-Si).
