    摘要:

    钙钛矿太阳能电池(PeSCs)因其高效率、低成本和简单的制备工艺而被认为是最有前途的光伏技术之一。PeSCs的能量转换效率和稳定性很大程度上取决于钙钛矿薄膜的质量和器件中的界面,它们是PeSCs非辐射复合损失的主要来源。天然生物材料具有丰富的资源、无毒和生物相容性等优点,在改善PeSCs的钙钛矿层和界面方面显示出巨大的潜力。本文综述了利用天然生物材料实现高性能PeSCs的最新进展。首先讨论了天然生物材料在钙钛矿薄膜的形貌优化、缺陷钝化和能级调控方面的作用;同时,也讨论了利用天然生物材料优化钙钛矿和电荷传输层之间的界面,以及构建可拉伸、可生物相容和可生物降解的电极的策略;最后,展望了PeSCs在天然生物材料方面的进一步发展。

    Abstract:

    Perovskite solar cells (PeSCs) have been considered as one of the most promising photovoltaic technologies due to their high efficiency, low-cost and facile fabrication process. The power conversion efficiency and stability of PeSCs highly depend on the quality of perovskite film and the interfaces in the device, which are the main sources of PeSCs nonradiative recombination losses. Natural biomaterials, with the advantages of earth-abundance, non-toxicity, and biocompatibility, have shown huge potential to improve both perovskite layer and interfaces in PeSCs. Herein, the latest progress using natural biomaterials to achieve high-performance PeSCs is reviewed. It’s discussed the roles of natural biomaterials on perovskite film in terms of morphology optimization, defect passivation and energetics modification. Meanwhile, the strategies using natural biomaterials to create superior interface between perovskite and charge transport layer, and to build stretchable, biocompatible, and biodegradable electrodes are present. Finally, an outlook on the further development of PeSCs with respect to natural biomaterials is provided.
