Experimental study of heat transfer in thin-film perovskite-based structures using a low-coherent tandem interferometry

Abstract

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 by a diffuse insolation does not exceed the threshold critical for the stability of the perovskite phase owing to dissipation into the environment, with the temperature maximum close to half of the overall thickness of the structure. Keywords: perovskite, thin film, heat transfer, solar cells, diffuse insolation.
