The interaction between sites A,B and X with passivation molecules is restricted when the conventional passivation strategy is applied in perovskite(ABX3)photovoltaics.Fortunately,the revolving A-site presents an opportunity to strengthen this interaction by utilizing an external field.Herein,we propose a novel approach to achieving an ordered magnetic dipole moment,which is regulated by a magnetic field via the coupling effect between the chiral passivation molecule and the A-site(formamidine ion)in perovskites.This strategy can increase the molecular interaction energy by approximately four times and ensure a well-ordered molecular arrangement.The quality of the deposited perovskite film is significantly optimized with inhibited nonradiative recombination.It manages to reduce the open-circuit voltage loss of photovoltaic devices to 360 mV and increase the power conversion efficiency to 25.22％.This finding provides a new insight into the exploration of A-sites in perovskites and offers a novel route to improving the device performance of perovskite photovoltaics.
