Solar energy will play a large role for the energy transition. More efficient solar cells are urgently needed to reduce the area required. Singlet fission is a way to make solar cells much more efficient. During singlet fission, a high-energy photon is converted into two particles of lower energy, called triplet excitons. This means that a solar cell can generate twice as much current from high-energy light. In this project we investigated ways to enhance the transfer of the triplet excitons into a conventional silicon solar cell. We found a robust way for transfer, yet the efficiency still needs improvement.
