Photon recycling has been proven to be an important process in metal halide perovskite thin films. We
propose a model of photon recycling based on the photon diffusion concept that can interpret experimental observations on the photoluminescence and transient spectroscopy in perovskite layers. Our model
shows how the photon recycling can enhance the apparent photocarrier lifetime and thereby slow down
the photoluminescence decay dynamics. We also discuss the interplay between photon recycling and the
photocarriers diffusive transport and demonstrate that at high carrier concentrations, photon recycling
dominates the diffusion, conveying the carriers inside the absorbing layer over long distances. We also
provide a quantitative determination of a diffusion length that is considerably expanded by the photon
recycling process. The effect of the photon recycling process on the Auger recombination rate is also
addressed here. The results provide insights for both interpreting the experimental observations and also
designing experimental schemes. [-]
