Abstract

Perovskite solar cells, also known as PSCs, have undergone significant advancements in photoelectric conversion efficiency and durability since the organic-inorganic hybridization polycrystalline was originally introduced in the discipline of optical technology. The possible commercial applications of PSCs are severely hampered by a number of problems related to flaws in PSCs, including energy shortages, ion migration, operation unpredictability, and repeatability. The genesis, categorization, nature, linkages, and overlapped consequences of faults in polycrystalline materials are described and evaluated here in an organized and thorough way. Shallow- and deep-level faults have characteristics according to their place in the electrical framework in relation to band borders, whereas point imperfections, undercoordinated particles, contaminants, and holes are classified using a dimension criterion. We review the existing theories on how harmful flaws cause non-radiative replication, charging entrapment and dispersion, ion immigration, and hyperbole, establishing a mostly unambiguous relationship between efficiency and flaws in films made of perovskite. Then, from a different angle, a summary of defect sterilization techniques is provided throughout the manufacturing pathway, covering film development, post-treatment, and interfacial architecture among the perovskite substrate and the charge transfer channel. On the basis of imperfect sterilization in the field, difficulties and recommendations to remove PSCs' commercialization roadblocks are put forth.
