Breaking Down Old Approximations To Help Develop Third Generation Solar Cells: A Quantum Mechanical Model For Singlet Fission

Strong interest in creating next-generation solar cells has renewed focus on singlet fission, where one absorbed photon converts into two triplet charge carriers. Utilization of singlet fission could lead to solar cells with efficiencies greater than the Shockley-Quiesser limit. Before effective design of such cells could be achieved, a fundamental understanding of the singlet fission mec
