The lead halide perovskite (LHP) nanocrystals (NCs) research area is flourishing due to their exceptional properties and great potential for a wide range of applications in optoelectronics and photovoltaics. Yet, despite the momentum in the field, perovskite devices are not yet ready for commercialization due to degradation caused by intrinsic phase transitions and external factors such as moisture, temperature, and ultraviolet (UV) light. To attain long-term stability, we analyze the origin of instabilities and describe different strategies such as surface modification, encapsulation, and doping for long-term viability. We also assess how these stabilizing strategies have been utilized to obtain optoelectronic devices with long-term stability. This Mini-Review also outlines the future direction of each strategy for producing highly efficient and ultrastable LHP NCs for sustainable applications.
由于其优异的性能以及在光电子学和光伏领域广泛应用的巨大潜力，卤化铅钙钛矿（LHP）纳米晶体（NCs）研究领域正蓬勃发展。然而，尽管该领域发展势头强劲，但由于内在相变以及诸如湿气、温度和紫外线（UV）光等外部因素导致的降解，钙钛矿器件尚未准备好实现商业化。为了实现长期稳定性，我们分析了不稳定性的根源，并描述了诸如表面改性、封装和掺杂等不同的长期可行性策略。我们还评估了这些稳定策略是如何被用于获得具有长期稳定性的光电器件的。本综述还概述了每种策略的未来方向，以便生产出用于可持续应用的高效且超稳定的LHP NCs。
