Abstract:

Perovskite solar cell technology is a key development direction for the next generation of solar cell technology due to its advantages of solution-processing, low cost and high theoretical efficiency. Long-term stability and large-scale production have become the biggest obstacles to the commercialization of perovskite solar cells. Carbon nanomaterials are ideal for improving device efficiency and stability due to their high electron mobility, tunable Fermi energy levels, and excellent stability. This paper summarizes the research progress of four typical carbon nanomaterials, including graphene, carbon nanotubes and fullerenes as electron transport materials in the application of perovskite solar cells. The mechanisms involved in several carbon nanomaterials for enhancing the efficiency and stability of perovskite solar cell devices are analyzed. Finally, the development prospect of carbon nanomaterials in the field of perovskite solar cells is outlooked, and it is believed that the future application of carbon nanomaterials can be focused on the rational structural modification of carbon nanomaterials in order to develop new carbon nanomaterials that are low-cost, solvent-processable, and rich in photovoltaic properties.
