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.

为减少利用未处理的短语树引入的关于方面词错误的句法信息,提出一种双句法交互图注意力网络模型。在现有短语树的基础上通过特定的句法拆分获得面向方面的短语子树,在此基础上,在短语树与依赖树之间利用各自的句法特点建立句法信息的交互通道,有效结合短语树与依赖树两棵句法树产生的句法信息。在3个公共数据集上的充分实验结果表明,双句法交互图注意力网络模型均优于当前的主流方法,验证了模型的有效性。
