In the quest for greater efficiency in solar cells and light-emitting diodes (LEDs), the energy loss associated with exciton-exciton annihilation poses a substantial barrier. Excitons, the bound states of electrons and holes that form when light interacts with semiconducting materials, are fleeting entities whose excited states are critical for energy conversion and light emission. However,
