| description | In this study, graphitic carbon nitride (g-C<sub>3</sub>N<sub>4</sub>) was extensively utilized as an electron transport layer or interfacial buffer layer for simultaneously realizing photoelectric performance and stability improvement of perovskite solar cells (PSCs). This review covers the different g-C<sub>3</sub>N<sub>4</sub> nanostructures used as additive and surface modifier layers applied to PSCs. In addition, the mechanism of reducing the defect state in PSCs, including improving the crystalline quality of perovskite, passivating the grain boundaries, and tuning the energy level alignment, were also highlighted in this review. Currently, the power conversion efficiency of PSCs based on modified g-C<sub>3</sub>N<sub>4</sub> has been increased up to 22.13%, and its unique two-dimensional (2D) package structure has enhanced the stability of PSCs, which can remain stable in the dark for over 1500 h. Finally, the potential challenges and perspectives of g-C<sub>3</sub>N<sub>4</sub> incorporated into perovskite-based optoelectronic devices are also included in this review. |
