Abstract
Layers of organic molecules are capable of generating multiple excitons per absorbed photon though a process known as singlet fission. As such, this process could be employed to fabricate a solar cell which circumvents the efficiency limits imposed by a single threshold design. Leveraging experience with silicon solar cells, the OMEGA Si project is developing a device that combines the maturity and high efficiency of crystalline silicon with the exciton multiplication afforded by singlet fission. This talk will communicate progress of the project including experiments to elucidate exciton and carrier transfer between the singlet fission layer and the underlying silicon solar cell.
