"solar panels lose substantial energy as excess heat when high-energy sunlight generates hot electrons that rapidly lose momentum before can be captured... overcome using hybrid organic-inorganic perovskite semiconductor/ large-bandgap organic acceptor... hot electrons harvested from bulk perovskite using ultrafast laser pulses, without needing complex energy-slowing strategies/ nanomaterials... hot electrons transfer smoothly into acceptor despite needing small boost overcoming interfacial energy barrier"
