"It is theoretically possible that the charging power of quantum batteries increases faster than the size of the battery which could allow new ways to speed charging... The active layer of the microcavity contains organic semiconductor materials that store the energy. Underlying the superabsorbing effect of the quantum batteries is the idea that all the molecules act collectively through a property known as quantum superposition"
