Perovskite solar cells (PSCs) have led to distinguished achievements and become one of the state-of-the-art photovoltaic technologies. Undoubtedly, reliable preparation of large area high-quality perovskite (PVK) films with uniform optoelectronic properties has become a critical and challenging task to transition PSCs from lab to market. Here, methyldiphenylphosphine oxide (MDPPO) is employed as an additive in a PVK precursor solution to promote uniform conductivity and carrier transport of PVK films. More important, to check its compatibility with the upscaling process, the MDPPO additive strategy was further applied to doctor-blade large-area PVK films. As a result, benefit from the favorable role of MDPPO additive, the power conversion efficiencies (PCEs) of small-area PSCs reach 23.85% with superb open circuit voltage (Voc) of 1.15 V and fill factor of 81.21%, while an impressive PCE of 19.22% was achieved for the large-area PSC minimodules with active area of 61.48 cm2. Remarkably, the MDPPO modified device exhibits significantly improved operational stability, maintaining an initial efficiency of 68% even after 750 h under continuous 1-sun illumination. Our achievements will provide profound insight and further guidance for the scale-up process of PSCs from lab to large-scale modules.

基于钙钛矿薄膜均匀性工程的大面积钙钛矿太阳能组件：甲基二苯基氧化膦添加剂的关键作用
钙钛矿太阳能电池（PSC）取得了杰出的成就，成为最先进的光伏技术之一。毫无疑问，可靠地制备具有均匀光电性能的大面积高质量钙钛矿（PVK）薄膜已成为PSC从实验室走向市场的关键且具有挑战性的任务。这里，甲基二苯基氧化膦（MDPPO）被用作PVK前驱体溶液中的添加剂，以促进PVK薄膜的均匀导电性和载流子传输。更重要的是，为了检查其与放大工艺的兼容性，MDPPO添加剂策略被进一步应用于刮刀大面积PVK薄膜。结果，受益于MDPPO添加剂的有利作用，小面积PSC的功率转换效率（PCE）达到23.85%，开路电压（ V oc ）为1.15 V，填充因子为81.21%，同时具有令人印象深刻的性能。大面积PSC微型模块的有效面积为61.48 cm 2 ，PCE达到19.22%。值得注意的是，经过 MDPPO 修饰的器件表现出显着提高的运行稳定性，即使在连续 1 太阳光照下 750 小时后仍保持 68% 的初始效率。我们的成果将为PSC从实验室到大规模模块的放大过程提供深刻的见解和进一步的指导。
