面向产业应用的大面积钙钛矿组件技术研究进展

Progress on Large-area Perovsktie Solar Cells: Toward Photovaltaic Application

摘要

钙钛矿太阳能电池（PSCs）因其高光电转换效率（PCE）制备成本低等优势，成为下一代光伏技术的有力竞争者。然而，在从实验室厘米级器件放大至平米级工业化组件过程中，随着PSCs器件面积增大，PCE出现大幅下降。这主要由于小面积器件的制备难以导入大面积组件的实际生产中。本综述从大面积钙钛矿光伏组件制备的关键技术出发，重点介绍薄膜沉积工艺、成核工程、添加剂工程以及界面调控策略。分析包括刮涂/狭缝涂布、真空闪蒸、气相辅助沉积、混合两步法等在内的可扩展制备技术，并探讨溶剂工程、添加剂工程、界面钝化等如何协同解决大面积薄膜的均匀性、缺陷控制及稳定性难题。最后，对大面钙钛矿光伏组件技术发展未来和产业化前景进行展望，旨在为钙钛矿光伏技术的规模化应用提供参考。

Abstract

Perovskite solar cells (PSCs) have shown huge potential for next generation photovaltaic due to tis high power conversion efficiency (PCE) and low costs. However, the PCE of PSCs decrease dramatically from lab-scale small area devices (1cm²) to large-area modules (＞800cm²) because of the diffirent fabrication method between spin-caoting and slot-die or blade coating. In this review, we summarized the key technologies in large-area PSCs fabrication, including scalable perovskite film deposition method, nucleation engineering, and interfacial passivation strategies. Finally, outlooks and challenges on large-area perovskite module for photovaltaic application were discussed.
