Illuminating perovskite photophysics

Scientists at KAUST have studied charge carrier behavior in perovskite thin films using laser pulses and terahertz radiation. They found that increased density of charge carriers narrows the energy gap for electrons to be excited by light, and charge carriers become more localized at higher densities.
