The hybrid organic–inorganic halide perovskite solar cells (PSCs) have attracted considerable attention in the photovoltaic community during the last decade due to unique properties, such as high absorption coefficient, solutionable fabrication, and compatibility with roll-to-roll technology. A certified power conversion efficiency of PSCs as high as 25.2% has been obtained, approaching the levels of silicon solar cells, copper indium gallium selenide (CIGS), and cadmium telluride (CdTe) thin-film solar cells. However, the device area of a PSC is one of the biggest challenges for the commercialize applications. To fabricate large-area PSCs, various fabrication methods have been proposed, including spray coating, slot-die coating, vacuum deposition, and blade coating. Here, the blade-coating technique progress for the PSC fabrication has been reviewed. Moreover, the optimized ways during the solution fabrication process, the efficient strategy for improving the perovskite films' morphology, have also been summarized in this work. In the last part, the challenges and opportunities of PSC commercialization have also been proposed.

钙钛矿太阳能电池叶片涂覆方法的商业化进展

在过去的十年中，有机-无机卤化物钙钛矿混合太阳能电池（PSC）由于其独特的特性（例如高吸收系数，可制造的解决方案以及与卷对卷技术的兼容性）而在光伏界引起了相当大的关注。已获得PSC的认证功率转换效率高达25.2％，已接近硅太阳能电池，硒化铜铟镓（CIGS）和碲化镉（CdTe）薄膜太阳能电池的水平。但是，PSC的设备面积是商业化应用程序面临的最大挑战之一。为了制造大面积的PSC，已经提出了各种制造方法，包括喷涂，狭缝模头涂覆，真空沉积和刮刀涂覆。这里，对PSC制造中的刮涂技术的进展进行了回顾。此外，这项工作还总结了溶液制备过程中的最佳方法，改善钙钛矿薄膜形态的有效策略。在最后一部分中，还提出了PSC商业化的挑战和机遇。
