Abstract

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).

具有稳定性认证的太阳能组件用交联剂稳定准二维钙钛矿

在确保长期稳定性的同时，将钙钛矿太阳能电池提升到组件水平对其商业化至关重要。在这里，我们报告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，以减少单个三维钙钛矿层之间的弱范德华间隙，并使NiOx/钙钛矿界面功能化。这种方法不仅增强了钙钛矿板在准二维结构内的耦合，从而增强了稳定性，而且还促进了高有序、相纯的低维钙钛矿薄膜的垂直生长，并改善了载流子输运。使用该方法制备的准二维钙钛矿太阳能组件（psm）在9.66 cm2的孔径面积上显示出16.05%的最佳效率，利用环境空气中的叶片涂层技术。同时，psm通过了VDE pr基金Zertifizierungsinstitut GmbH （VDE Institute）的标准湿热和运行稳定性测试，测试时间为1000小时，退化可以忽略。
