A new ionic liquid crystal (ILC, 1-Dodecyl-3-methylimidazolium tetrafluoroborate) was developed to modify buried interface of perovskite solar cells (PSC). The ILC promotes a preferential growth of perovskite along [001] direction and exhibits strong interaction with perovskite to passivate defects. The ILC-modified PSC delivers an efficiency of 24.92 % and maintains 94 % of the original value after storage in ambient for 3000 h.
