Insight into Photon Recycling in Perovskite Semiconductors from the Concept of Photon Diffusion

Photon recycling (emission and reabsorption inside a semiconductor layer) is a fundamental issue for enhancing the performance of hybrid perovskite materials as photovoltaic absorbers. Interpreting photon-recycling effects is not trivial, though, due to complex interplay between carrier transport and recombination and the optical properties of the involved surfaces. The authors present a model of recycling effects based on the concept of photon diffusion, and show that this approach can explain recent experimental observations regarding the optical response of the perovskite layers. These results can guide the improvement of the optoelectronic performance of metal halide perovskites.
