Abstract: Using the photovoltaic effect to directly convert solar energy into electricity is one of the important ways to obtain sustainable clean energy. In recent years, perovskite solar cells have become a research hotspot in the field of photovoltaics. With the continuous development of structural regulation and preparation technology, the current efficiency had exceeded 25%. Although perovskite photovoltaic devices have the advantages of mild preparation conditions, low cost, and high efficiency. However, this type of photovoltaic device exhibits a slow kinetic phenomenon on the order of seconds or even minutes, which has caused great problems for the performance of perovskite photovoltaic devices and the correct understanding of photoelectric conversion kinetics. So far, the understanding of slow dynamics is still in the guessing stage, and there is still no systematic understanding. Among them, ion migration and trap-state properties are considered as the main research targets of slow dynamics. Starting from the original charge separation of perovskite photovoltaic devices, this paper analyzes the carrier dynamics of perovskite solar cells over multiple time spans. The possible reasons for the slow dynamics of perovskite photovoltaic devices are discussed. It is believed that the key perovskite active layer can be used as the entry point to reveal the mechanism of the influence of the perovskite active layer structure on the slow kinetics. It provides new ideas for a new understanding of the photoelectric conversion process of perovskite solar cells, and further guides device design and preparation.
