In recent years, perovskite solar cells have developed rapidly, whose photoelectric conversion efficiency has exceeded 27%. As an important part of it, the electron transport layer affects the performance and stability of the battery. The film-forming quality, interface defect passivation, charge extraction and transport of perovskite solar cells are closely related to the electron transport layer, and are also the key to breaking through the performance bottleneck. Therefore, systematically analyzing and comparing the properties, optimization strategies, and influence mechanisms of different fullerene derivatives is of great significance for improving the stability of devices and facilitating industrial production. This review aims to analyze the impact of different electron transport layer materials on the performance of perovskite cells, explain the underlying mechanisms, and provide references for future, deeper mechanism studies and large-scale commercial production. This review not only provides theoretical guidance for the design and development of high-performance, low-cost electron transport materials, but also lays a foundation for advancing the commercialization process of perovskite solar cells.
