摘要:
当前，钙钛矿太阳能电池正逐步实现产业化，但器件本身界面缺陷的存在、层间的能级错配、钙钛矿薄膜质量不佳等因素都会影响其最终效率和长期稳定性，仍有相当的优化空间。制备工艺的优化关乎产品的使用效果与制造成本，自组装单分子层修饰界面的应用有助于解决上述问题。自组装单分子层挤出工艺是当前钙钛矿太阳能电池空穴传输层研究领域的前沿技术，核心是利用分子设计与结晶动力学调控，使功能分子在钙钛矿成膜过程中自发迁移并组装于界面，同步实现缺陷钝化与能级匹配，简化工艺流程，显著提升器件效率与稳定性，为钙钛矿太阳能电池的研究与产业化发展提供了重要技术路径。当前最优器件可实现26.83%光电转换效率，可在最大功率点稳定运行超2500 h。但该种器件仍面临大面积制备均匀性不足、长期稳定性有待提升、成本较高及表征技术不完善等核心挑战。简要介绍了自组装单分子层挤出工艺发展历程并对其未来优化策略和应用进行了展望。
Abstract:
Currently, perovskite solar cells are gradually moving towards industrialization. However, factors such as interfacial defects in the devices, energy-level mismatch between layers and the poor quality of perovskite films affect their final efficiency and long-term stability, leaving considerable room for optimization. The optimization of fabrication processes is critical to the performance and manufacturing cost of products, and the application of selfassembled monolayers modification at the interface is helping to address the above issues. The self-assembled monolayers extrusion process is a cuttingedge technology in the research of hole transport layer for perovskite solar cells. Its core lies in the regulation of molecular design and crystallization kinetics, enabling functional molecules to spontaneously migrate and assemble at the interface during perovskite film formation. This simultaneously achieves defect passivation and energy-level alignment, simplifies the fabrication process, significantly improves device efficiency and stability, providing an important technical route for the research and industrialization of perovskite solar cells. The stateoftheart device achieves a power conversion efficiency of 26.83% and stable operation for over 2500 h at the maximum power point. Nevertheless, it still faces key challenges, including insufficient uniformity in large-area fabrication, limited long-term stability, relatively high cost and immature characterization techniques. This paper briefly reviews the development history of self-asembled monolayers extrusion process and provides an outlook on its future optimization strategies and applications.
