尽管钙钛矿太阳能电池（PeSC）的功率转换效率（PCE）急剧上升，但围绕原型三维（3D）钙钛矿MAPbI 3（MA = CH 3 NH3）的长期稳定性以及再现性差的担忧可能会破坏商业化。我们报道了一系列二维钙钛矿化合物（PEI）2（MA）n− 1 PbnI 3 n +1（n = 3，5，7）的制备和性质，通过将聚乙烯亚胺（PEI）阳离子引入层状结构中。在多层膜中使用插层聚合物阳离子的好处是多方面的：与其3D MAPbI 3类似物相比，防潮性和膜质量大大提高;与使用小分子庞大铵的2D材料相比，太阳能电池内的电荷传输也可以得到改善。多层钙钛矿材料的水分稳定性质允许在环境湿度下简单一步制造具有2.32 cm 2孔径面积的电池，其具有PCE...
Despite the dramatic rise in power conversion efficiencies (PCEs) of perovskite solar cells (PeSCs), concerns surrounding the long-term stability as well as the poor reproducibility in the archetypal three-dimensional (3D) perovskite, MAPbI3 (MA = CH3NH3), have the potential to derail commercialization. We have reported the fabrication and properties of a series of 2D perovskite compounds (PEI)2(MA)n−1PbnI3n+1 (n = 3, 5, 7) by incorporating polyethylenimine (PEI) cations within the layered structure. The benefits of using intercalated polymer cations in the multilayered films are multiple: moisture resistance and film quality are greatly enhanced compared to that of their 3D MAPbI3 analogue; charge transport within solar cells can also be improved compared to that of 2D materials using small-molecule bulky ammonium. The moisture-stable nature of the multilayered perovskite materials allow for the simple one-step fabrication of cells with an aperture area of 2.32 cm2 under ambient humidity that have a PCE ...
