Inverted perovskite solar cells have gained significant attention due to their potential for high efficiency and stability. In the process, the active layer fabrication plays a key role in determining the performance of the solar cells. Gas quenching is an important technique in the preparation of perovskite solar cells as it enhances the film quality and solar cell performance by precisely controlling the crystal growth and minimizing defects. As for the post-treatment of the active layer, surface passivation plays a crucial role in enhancing the performance of perovskite solar cells by reducing surface defects of perovskite interfaces. This study explores the influence of different passivation materials on the morphology of perovskite films and the performance of gas-quenching assisted FA0.8Cs0.2Pb(I0.6Br0.4)3 solar cells. This work provides a practical solution for the production of low-cost and high-performance inverted perovskite solar cells while maintaining operational stability in real-world environments.
