Deskripsi
Highlights An effective buried interface stabilization strategy based on synergistic effect of fluorine and sulfonyl functional groups is proposed. The correlations between molecular structures, defect passivation, interfacial energy band alignment, perovskite crystallization and device performance are established. The device with KFSI achieves an impressive efficiency of 24.17%.
