a Exciton diffusion constant D and diffusion length L0 for n ranging from 1 to 5. D and L0 increase as n increases. The error bars are estimated from the sensitivity of model to the parameters. b Total annihilation rate as a function of n for (BA)2(MA)n-1PbnI3n+1, showing enhanced annihilation at decreasing n. As a comparison, the exciton recombination rates k1 are denoted by the circles.
