Biomaterial Improves the Stability of Perovskite Solar Cells by Passivating Defects and Inhibiting Ion Migration

“…According to the Lewis acid–base theory, the positively charged uncoordinated Pb 2+ can be passivated by the Lewis base, which has strong electron-donating ability through chemical bonds. ,, On the contrary, electron-rich defects like I – should be passivated by Lewis acid with strong electron-accepting ability . The ideal passivation material should include both electron donor and electron acceptor function groups to neutralize or anchor cationic and anionic defects simultaneously. − According to previous reports, the hydroxyl group and carbonyl group are effective functional groups for passivating perovskite films. − In early 2017, Xu et al. introduced ascorbic acid into Pb/Sn-based binary PSCs.…”

SnO2 Interacted with Sodium Thiosulfate for Perovskite Solar Cells over 25% Efficiency

“…Perovskite solar cells (PSCs) as a promising next-generation photovoltaic technology have drawn extensive attention from both academia and industry thanks to the advantages of solution processability, high defect tolerance, tunable bandgap, high efficiency, and low cost − as well as compatibility with a flexible substrate for lightweight products. − Since tremendous efforts have been taken to increase perovskite crystallinity and passivate the deep-level traps located mainly at the perovskite film surface and shallow-level traps prevalent in the bulk, − more attention has focused on the optimization of commonly used carrier transportation materials (CTMs) and development of novel CTMs with more advanced properties with low synthesis cost because CTMs play a crucial role in charge carrier transportation and extraction.…”
