Structural fluctuations cause spin-split states in tetragonal (CH(3)NH(3))PbI(3) as evidenced by the circular photogalvanic effect

Lead halide perovskites are used in thin-film solar cells, which owe their high efficiency to the long lifetimes of photocarriers. Various calculations find that a dynamical Rashba effect could significantly contribute to these long lifetimes. This effect is predicted to cause a spin splitting of th...
