      abstract     = {Photon recycling is a fundamental physical process that
                      becomes especially important for photovoltaic devices that
                      operate close to the radiative limit. This implies that the
                      externally measured radiative decay rate deviates from the
                      internal radiative recombination rate of the material. In
                      the present Letter, the probability of photon recycling in
                      organic lead halide perovskite films is manipulated by
                      modifying the underlying layer stacks. We observe
                      recombination kinetics by time-resolved photoluminescence
                      that is controlled by the optical design of the chosen layer
                      structure. Quantitative simulations of decay rates and
                      emission spectra show excellent agreement with experimental
                      results if we assume that the internal bimolecular
                      recombination coefficient is ~ 66 $\%$ radiative.},
