Abstract: The effect of pyridine-based ligands, capable of coordinating e improving stability with Pb²⁺ defect sites through nitrogen atoms, on the photostability of MAPbI₃ thin films under solar radiation of 70–80mWcm⁻² at 50–60°C in an inert atmosphere has been investigated using UV-VIS spectroscopy, X-ray diffraction analysis and atomic force microscopy. It has been found that the addition of 4,4′-bipyridine to the perovskite precursor improves the photostability of a MAPbI₃ thin film, withstanding illumination for 1400h.

Keywords: perovskite films, perovskite solar cells, additive, pyridine-based ligand, stability, MAPbI₃, thin films.
