Strong light-matter coupling has shown great potential for modifying theelectro-optical properties of semiconducting materials in recent years. In thestrong coupling regime, excitons and cavity photons form new states namedexciton-polaritons, with their properties a hybrid of each constituent. Herein,we report strong coupling observed in solution-processed donor:acceptorbulk-heterojunction organic solar cells (OSCs) evidenced by the observed Rabisplitting of ~300 meV and the effects of strong coupling on OSC operations.Combining the transient photovoltage decay measurement and nanosecond transientabsorption spectroscopy, our results reveal that the effective charge carrierlifetimes are longer in cavity devices, attributed to the reduced bimolecularrecombination. It is also found that access to CT state(s) of higher energy isenabled in cavity devices. This study demonstrates that strong coupling caneffectively modify the device- and photo-physics in OSCs and opens a newpathway for engineering more efficient OSCs.
