## Description

- description: Halide perovskite solar cells (PSCs) with state-of-the-art efficiencies
    consist of thermally unstable methylammonium (MA). In this report, we have employed
    the surface passivation method with multifunctional fluoroarene molecule, which
    suppresses the formation of PbI2 and δ-perovskite phase in MA/Br-free perovskite
    film. The penta fluoro-phenylhydrazine (SF -PHZ) passivation effectively mitigates
    the defects at surface or grain boundaries in perovskite film with fluoroarene
    embedded interfacial layer as a consequence of stronger halogen bonding with fluoroarene
    moieties or NH-NH2 terminal. As a result, the PSC with a p-i-n configuration achieved
    superior operational thermal stability and a PCE exceeding 22 % with a large area
    of ~1 cm2, This work underscores a universal strategy for defect passivation to
    further improvement of efficiency using a multifunctional passivator. This report
    gives insights into the film growth properties, device photo-physics, and defect
    analysis correlating with device performance and device stability.
