Solution processing of hybrid perovskite semiconductors is a highly promising approach for the fabrication of cost-effective electronic and optoelectronic devices. However, challenges with this approach lie in overcoming the controllability of the perovskite film morphology and the reproducibility of device efficiencies. Here, a facile and practical aging treatment (AT) strategy is reported to modulate the perovskite crystal growth to produce sufficiently high-quality perovskite thin films with improved homogeneity and full-coverage morphology. The resulting AT-films exhibit fewer defects, faster charge carrier transfer/extraction, and suppressed non-radiative recombination compared with reference. The AT-devices achieve a noticeable improvement in the reproducibility, operational stability, and photovoltaic performance of devices, with the average efficiency increased by 16%. It also demonstrates the feasibility and scalability of AT strategy in optimizing the film morphology and device performance for other perovskite components including MAPbI3, (MAPbBr3)15(FAPbI3)85, and Cs0.05(MAPbBr3)0.17(FAPbI3)0.83. This method opens an effective avenue to improve the quality of perovskite films and photovoltaic devices in a scalable and reproducible manner.

基于老化处理的高重复性和高质量钙钛矿薄膜的实用方法
混合钙钛矿半导体的溶液加工是制造具有成本效益的电子和光电器件的一种非常有前途的方法。然而，这种方法的挑战在于克服钙钛矿薄膜形貌的可控性和器件效率的再现性。在这里，报道了一种简便实用的时效处理（AT）策略来调节钙钛矿晶体生长，以产生具有改善的均匀性和全覆盖形态的足够高质量的钙钛矿薄膜。与参考相比，所得 AT 薄膜表现出更少的缺陷、更快的载流子转移/提取以及抑制的非辐射复合。 AT-器件在器件的再现性、运行稳定性和光伏性能方面实现了显着改善，平均效率提高了16%。它还证明了 AT 策略在优化其他钙钛矿组件的薄膜形貌和器件性能方面的可行性和可扩展性，包括 MAPbI 3 、(MAPbBr 3 ) 15 (FAPbI 3 ) 85和 Cs 0.05 (MAPbBr 3 ) 0.17 (FAPbI 3 ) 0.83 。该方法为以可扩展和可重复的方式提高钙钛矿薄膜和光伏器件的质量开辟了一条有效途径。
