Excitons are neutral quasiparticles, which are investigated as a potential component to improve the performance of photovoltaic cells however it is first necessary to develop methods to achieve multiexciton generation such as singlet fission. To this end the authors theoretically and experimentally demonstrate long-lived triplet exciton states via singlet fission enabled by the intermolecular coupling geometries in pentacene films.
