摘要：反式钙钛矿太阳电池制备工艺简单、性能优异,并且可与其他光伏电池制备高效率叠层器件,已成为极具商业化前景的新型光伏技术.近年来,锚定组装型空穴传输材料已经成为反式钙钛矿太阳电池中的研究热点.这类材料可在透明导电氧化物电极上形成均匀的薄膜,最大程度减少电荷传输损耗和光学损失,从而同时提高钙钛矿太阳电池的开路电压、填充因子和短路电流,显著提升光电转化效率.此外,锚定组装型空穴传输材料具有分子自组装特性,可精准调控界面性质,优化与钙钛矿层的能级匹配,降低电荷复合,同时改善薄膜的均匀性与稳定性.本文从锚定组装型空穴传输分子的末端基团、连接基团和锚定基团三个部分系统讨论了分子结构与应用性能之间的关系,综述了反式结构钙钛矿太阳电池中锚定组装型空穴传输材料的研究进展与应用挑战.
Inverted perovskite solar cells(PSCs),owing to their simple preparation process,excellent performance,and the advantage of being able to prepare tandem devices with other photovoltaic cells,have gained significant attention as a next-generation photovoltaic technology.In recent years,the development and application of anchored self-assembled hole-transporting materials,also known as self-assembled monolayers(SAMs),have emerged as a focal point of research in inverted PSCs.Depositing such materials on transparent conducting oxide electrodes(TCO)can form a uniform thin layer,which minimizes charge transport loss and optical loss,thereby simultaneously improving the open-circuit voltage,fill factor,and short-circuit current of perovskite solar cells,significantly enhancing the power conversion efficiency.Beyond their electrical advantages,anchored self-assembled hole-transporting materials possess unique molecular self-assembly capabilities that allow for precise regulation of interfacial energetics and morphology.By tuning the alignment of energy levels between the hole-transporting layers(HTLs)and the perovskite layer,suppressing charge recombination,and improving the uniformity and stability of the interface,these materials contribute to both efficiency and durability improvements.Starting from the terminal groups,spacer groups,and anchoring groups of the anchored assembled hole-transporting molecules,this paper focuses on the structure-performance relationship and reviews the research progress and challenges of anchored assembled hole-transporting materials in inverted perovskite solar cells.The terminal group,typically consisting of carbazole,triphenylamine,or phenothiazine derivatives,plays a critical role in energy level alignment,hole extraction efficiency,and interfacial passivation.π-conjugated and functionalized terminal units have been shown to enhance the wettability,dipole moment,and film-forming properties of anchored assembled hole-transporting materials,contributing to improved device stability and reduced non-radiative recombination.Spacer units,including alkyl chains and aromatic bridges,modulate the molecular conformation,interfacial coverage,and charge tunneling dynamics.Notably,the transition from flexible alkyl chains to rigid conjugated linkers enhances molecular packing,dipole orientation,and operational stability.Anchoring groups such as phosphonic acid,carboxylic acid,sulfonic acid,and boric acid govern the chemical binding to metal oxide substrates like ITO and NiO x,impacting film robustness and interfacial stability.This review highlights the critical interplay between molecular design and device-level performance,providing comparative analyses of key anchored assembled hole-transporting molecules,and aims to offer valuable insights into the key design principles.Future research should address scalability,long-term stability,and the elucidation of dynamic self-assembly mechanisms through in situ and non-destructive characterization techniques.Such advancements are expected to accelerate the rational design of next-generation interfacial materials for high-efficiency,stable,and commercially viable perovskite solar technologies.
