Abstract

Despite the significant breakthroughs in photoelectric conversion efficiency achieved by perovskite solar cells, their temperature stability remains a significant bottleneck to commercialization. Temperature fluctuations typically lead to structural changes and phase transformations in perovskites. Additionally, thermal stress can facilitate ion migration within the perovskite material, resulting in interface charge accumulation and electrode corrosion, which ultimately undermines the performance of perovskite devices. This brief perspective systematically discusses the mechanisms behind device performance degradation under temperature cycling conditions and presents potential improvement strategies to address these issues. Finally, we elaborate on the future challenges that must be overcome for the successful commercialization of these devices.

p-i-n钙钛矿太阳能电池温度稳定性研究进展

尽管钙钛矿太阳能电池在光电转换效率方面取得了重大突破，但其温度稳定性仍然是商业化的重要瓶颈。温度波动通常会导致钙钛矿的结构变化和相变。此外，热应力会促进钙钛矿材料内部离子迁移，导致界面电荷积累和电极腐蚀，最终破坏钙钛矿器件的性能。这个简短的观点系统地讨论了在温度循环条件下器件性能下降的机制，并提出了解决这些问题的潜在改进策略。最后，我们详细阐述了这些设备成功商业化必须克服的未来挑战。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
