Abstract: 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 MAPbI$_3$, (MAPbBr$_3$)$_{15}$(FAPbI$_3$)$_{85}$, and Cs$_{0.05}$(MAPbBr$_3$)$_{0.17}$(FAPbI$_3$)$_{0.83}$. This method opens an effective avenue to improve the quality of perovskite films and photovoltaic devices in a scalable and reproducible manner.
