摘要:
目前，钙钛矿太阳能电池光电转换效率已突破27%，但稳定性不足仍是阻碍其商业化的核心瓶颈。采用小分子钝化界面/体相缺陷是目前广泛使用的有效改进策略。然而，小分子与钙钛矿之间的相互作用有限，在极性溶剂冲洗、长期热或光照下易发生脱附、迁移或降解，不仅导致钝化作用衰减，甚至可能沦为离子迁移的“助剂”。相比之下，将小分子以共价键连接，构筑长链缠结的聚合物结构，可有效提升其热稳定性与抗迁移能力，但固有的溶解性较差的问题限制了聚合物在钙钛矿体系中的直接应用。为兼顾小分子的可加工性与聚合物的本征稳定性，原位聚合策略应运而生：将具有聚合活性的单体分散于钙钛矿层或界面层中，在成膜过程中借助热、光或催化剂引发聚合，原位构建共价交联的网络结构。原位聚合策略在提升器件稳定性的同时，也维持了器件的高效率，最高获得了26.83%的效率。系统梳理了近年来基于不同反应类型的原位聚合在钙钛矿太阳能电池中的应用进展，阐述了该反应在体相钝化、界面修饰及应力调控等方面的多重作用，并分析了当前面临的关键问题，旨在为高效稳定钙钛矿太阳能电池的理性设计提供参考。
Abstract:
Currently, the power conversion efficiency of perovskite solar cells has exceeded 27%, yet insufficient stability remains the core bottleneck hindering their commercialization. Employing small molecules to passivate interfacial/bulk defects is a widely adopted and effective strategy. However, the interaction between small molecules and perovskites is limited, making them prone to desorption, migration or degradation under polar solvent rinsing, prolonged heat or light exposure. This not only leads to the attenuation of the passivation effect， but may even turn them into “promoters” for ion migration. In contrast, connecting small molecules via covalent bonds to construct longchain entangled polymer structures can effectively enhance their thermal stability and resistance to migration. Nevertheless, the inherent poor solubility issues of polymers limits their direct application in perovskite systems. To combine the processability of small molecules with the intrinsic stability of polymers, the in-situ polymerization strategy has emerged. This approach involves dispersing polymerizable monomers within the perovskite layer or at the interfaces, where polymerization is triggered by heat, light or catalysts during film formation to construct a covalent crosslinked network in situ. The in-situ polymerization strategy enhances device stability while maintaining high efficiency, achieving a maximum power conversion efficiency of 26.83%. This article systematically reviews recent research progress on the application of insitu polymerization with different reaction types in perovskite solar cells. It elaborates on the multifaceted roles of the in-situ polymerized network in bulk passivation, interface modification and stress regulation, while also analyzing current key challenges. This review aims to provide a reference for the rational design of highly efficient and stable perovskite solar cells.
