## Description

- description: Tin- perovskite solar cell (Sn-PSC) is limited by their poor stability
    arising from facile tin oxidation and uncontrolled film growth. Here, we introduced
    a multifunctional bidentate ligand, formohydrazide (FHZ) as an additive into FASnI3
    perovskite film. This additive is found to be effective for the control of Sn-oxidation
    and forms pin-hole free film morphology. The Sn-PSCs with FHZ additive enhanced
    the device efficiency from 9.93% (for control Sn-HaP) to 13.14 % (for device with
    FHZ additive) with higher reproducibility and superior device stability. The device
    analysis suggests that the hydrazide additive significantly passivates the bulk
    and surface defect in the Sn-PSCs. This report gives insights into the film growth
    properties, device photo-physics, and defect analysis correlating with device
    performance and device stability.
