摘要:
倒置（p-i-n）钙钛矿太阳能电池因其优异的稳定性潜力与工艺兼容性而备受关注，其中，[6,6]苯基-C61-丁酸甲酯（PCBM）作为电子传输层材料发挥着不可替代的作用。然而，传统PCBM层被视为简单的电子抽取和物理覆盖层，其固有的光照/热致二聚化以及与钙钛矿表面缺陷的非理想接触，严重制约了器件效率与长期稳定性的进一步提升。综述了近年来PCBM钙钛矿界面工程领域从简单覆盖到主动调控的范式转变，首先剖析了PCBM在钙钛矿电池中不稳定和器件性能衰减的根本原因；进而重点阐述了目前前沿的电子传输层PCBM改性的主动调控策略，一是通过分子掺杂剂引导PCBM分子有序排列、优化能级并抑制二聚化；二是设计合成功能化PCBM衍生物，赋予界面层化学捕获I2并促进其解离再生I-的动态自修复能力；三是利用原位聚合构建三维网络结构，物理抑制PCBM分子的热聚集与相分离，同时通过配位键增强界面机械耦合。研究结果表明，这些主动界面工程策略通过协同优化分子排布、能级对齐、缺陷钝化及碘循环管理，实现了器件效率（>26%）与工作稳定性（如最大功率点跟踪下>1000 h）的同步突破。最后展望了面向商业化和多功能集成的PCBM电子传输层的设计，为开发高效、稳定的钙钛矿光伏器件提供了设计思路。
Abstract:
Inverted (p-i-n) perovskite solar cells have attracted significant attention due to their excellent stability potential and process compatibility. Among the key materials, [6,6]phenyl-C61-butyric acid methyl ester (PCBM) plays an irreplaceable role as the electron transport layer material. However, the conventional PCBM layer is often regarded as a simple electron extraction and physical capping layer. Its inherent light/heatinduced dimerization and nonideal contact with perovskite surface defects severely limit further improvements in device efficiency and longterm stability. This review summarizes the recent paradigm shift in the field of PCBM-perovskite interface engineering, from simple coverage to active regulation. First, the root causes of instability and device performance degradation associated with PCBM in perovskite solar cells are analyzed. Then, three cutting-edge strategies for actively regulating the modified PCBM electron transport layer are focused. The first strategy uses molecular dopants to guide the ordered arrangement of PCBM molecules, optimize energy levels and inhibit dimerization. The second strategy involves designing and synthesizing functionalized PCBM derivatives,which endow the interface layer with the ability to chemically capture iodine molecules, and promote their dissociation and regeneration into iodide ions for dynamic selfhealing. The third strategy employs in-situ polymerization to construct a three-dimensional network structure, which physically suppresses the thermal aggregation and phase separation of PCBM molecules while enhancing interfacial mechanical coupling through coordination bonds. Research results show that these active interface engineering strategies achieve simultaneous breakthroughs in device efficiency (over 26%) and operational stability (eg, over 1000 h under maximum power point tracking) by synergistically optimizing molecular arrangement, energy level alignment, defect passivation and iodine cycle management. Finally, this review provides design insights for developing PCBM electron transport layers that are both commercially viable and multifunctional, offering a pathway to efficient and stable perovskite photovoltaic devices.
