The heat transfer in an archetypal system ‘solar cell/environment’ was analyzed, in which the solar cell was a thin-film multilayer structure with a hybrid lead-iodide perovskite photoabsorber. The temperature field was mathematically modeled and heat maps of the cell at various irradiation intensities were calculated. It was found that the heating of the structure by a diffuse insolation has a maximum at about half of the overall thickness, but it does not exceed the threshold critical for the stability of the perovskite phase owing to dissipation into the environment.
