Even though power conversion efficiency has already reached 25.8%, poor stability is one of the major challenges hindering the commercialization of perovskite solar cells (PSCs). Several initiatives, such as structural modification and fabrication techniques by numerous ways, have been employed by researchers around the world to achieve the desired level of stability. The goal of this review is to address the recent improvements in PSCs in terms of structural modification and fabrication procedures. Perovskite films are used to provide a broad range of stability and to lose up to 20% of their initial performance. A thorough comprehension of the effect of the fabrication process on the device's stability is considered to be crucial in order to provide the foundation for future attempts. We summarize several commonly used fabrication techniques – spin coating, doctor blade, sequential deposition, hybrid chemical vapor, and alternating layer-by-layer. The evolution of device structure from regular to inverted, HTL free, and ETL including the changes in material utilization from organic to inorganic, as well as the perovskite material are presented in a systematic manner. We also aimed to gain insight into the functioning stability of PSCs, as well as practical information on how to increase their operational longevity through sensible device fabrication and materials processing, to promote PSC commercialization at the end.

钙钛矿太阳能电池的稳定性：问题与前景
尽管能量转换效率已达到25.8%，但稳定性差是阻碍钙钛矿太阳能电池（PSC）商业化的主要挑战之一。世界各地的研究人员已采用多种举措，例如通过多种方式进行结构修改和制造技术，以达到所需的稳定性水平。本次审查的目的是解决 PSC 在结构修改和制造程序方面的最新改进。钙钛矿薄膜用于提供广泛的稳定性，但会损失高达 20% 的初始性能。彻底理解制造工艺对器件稳定性的影响被认为是至关重要的，以便为未来的尝试奠定基础。我们总结了几种常用的制造技术——旋涂、刮刀、顺序沉积、混合化学气相和逐层交替。系统地呈现了器件结构从规则到倒置、无HTL和ETL的演变，包括材料利用率从有机到无机的变化，以及钙钛矿材料。我们还旨在深入了解 PSC 的功能稳定性，以及如何通过合理的器件制造和材料加工来延长其运行寿命的实用信息，以最终促进 PSC 的商业化。
