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 *** 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.

Lattice strain suppresses point defect formation in halide perovskites

We computationally investigate the impact of crystal strain on the formation of native point defects likely to be formed in halide perovskites;A-site cation antisite(I_(A)),Pb antisite(I_(Pb)),A-site cation vacany(V_(A)),I vacancy(V_(I)),Pb vacancy(V_(Pb)),and I interstitial(I_(i)).We systematically identify compressive and tensile strain to CsPbI_(3),FAPbI_(3),and MAPbI_(3)perovskite *** observe that while each type of defect has a unique behaviour,overall,the defect formation in FAPbI3 is much more sensitive to the *** compressive strain can enhance the formation energy of neutral I_(Pb)and I_(i)up to 15%for FAPbI_(3),depending on the growth *** show that the strain not only controls the formation of defects but also their transition levels in the band gap:A deep level can be transformed into a shallow level by the *** anticipate that tailoring the lattice strain can be used as a defect passivation mechanism for future studies.
