"instead of diffusing randomly through material... splitting exciton into free electron/ hole often involves energy loss, overcome harnessing coherent vibrations achieving ultrafast/ highly efficient ballistic movement... electrons move on the same clock as the atoms, proving that the ultimate speed of a solar material depends as much on its vibrations as its electronic structure... organic solar cells, photodetectors, photocatalytic systems for clean hydrogen production"
