Upscaling perovskite solar cells to the module level while ensuring long-term stability is crucial for their commercialization. Here, we report a bottom-up crosslinking strategy utilizing 4-(aminomethyl)benzoic acid as a dual-anchor linker integrated into quasi-two-dimensional (2D) perovskite to reduce the weak van der Waals gap between individual 3D perovskite layers and to functionalize the NiO_x/perovskite interface. This approach not only enhances the coupling of the perovskite slabs within the quasi-2D structure, leading to enhanced stability, but it also promotes the vertical growth of highly ordered, phase-pure low-dimensional perovskite films with improved carrier transport. The quasi-2D perovskite solar modules (PSMs) fabricated using this method have demonstrated an optimal efficiency of 16.05% over an aperture area of 9.66 cm², utilizing a blade-coating technique in ambient air. Meanwhile, the PSMs have passed the standard damp-heat and operational stability tests for 1,000 h with negligible degradation, as verified by the VDE Prüfund Zertifizierungsinstitut GmbH (VDE Institute).

用于太阳能组件的交联剂稳定的准二维钙钛矿，具有经认证的稳定性


将钙钛矿太阳能电池放大到组件级，同时确保长期稳定性，对于其商业化至关重要。在这里，我们报道了一种自下而上的交联策略，利用 4-（氨基甲基）苯甲酸作为双锚连接剂集成到准二维 （2D） 钙钛矿中，以减少单个 3D 钙钛矿层之间的弱范德华间隙，并使 NiO_x/钙钛矿界面功能化。这种方法不仅增强了准 2D 结构内钙钛矿板的耦合，从而提高了稳定性，而且还促进了高度有序、相纯的低维钙钛矿薄膜的垂直生长，并改善了载流子传输。使用这种方法制造的准 2D 钙钛矿太阳能组件 （PSM） 在环境空气中利用叶片涂层技术，在 9.66 cm² 的孔径面积上显示出 16.05% 的最佳效率。同时，PSM 已通过 1,000 小时的标准湿热和运行稳定性测试，退化可忽略不计，由 VDE Prüfund Zertifizierungsinstitut GmbH（VDE 研究所）验证。
