摘要:

钙钛矿太阳能电池以其优异的光电转换效率、低廉的制造成本和简便的制备工艺而备受瞩目,有望成为下一代光伏技术。 然而,其长期稳定性问题和潜在的铅泄漏风险严重阻碍了其商业化进程。 反式钙钛矿太阳能电池(iPSCs)凭借其优异的稳定性,成为研究热点。 自组装单分子层(SAMs)作为一种新型的空穴选择层(HSL)材料,因其定制化的分子剪裁策略和优异的界面调控能力,为解决iPSCs的稳定性和效率问题提供了新的途径。 本文综述了SAMs在iPSCs中的应用进展,详细讨论了SAMs的分子结构设计、沉积方法以及其在能级调控、缺陷钝化和界面改性方面的作用机制。 此外,本文还探讨了顺序沉积和共组装(Co-SAMs)策略以进一步提升器件性能。 最后,对SAMs技术面临的挑战和未来的发展方向进行了展望,包括大面积制备、长期稳定性提升、成本降低以及新型SAMs分子的设计等。 SAMs技术有望推动iPSCs的高效、稳定和低成本商业化,为清洁能源的可持续发展做出贡献。

Abstract:

Perovskite solar cells have attracted significant attention as a promising next-generation photovoltaic technology due to their excellent power conversion efficiency, low manufacturing cost, and simple fabrication process. However, their long-term stability and potential lead leakage severely hinder their commercialization. Inversed perovskite solar cells (iPSCs), with their superior stability, have become a research hotspot. Self-assembled monolayers (SAMs), as a novel hole-selective layer (HSL) material, offer a new approach to address the stability and efficiency issues of iPSCs due to their customizable molecular tailoring strategies and excellent interfacial control capabilities. This review summarizes the progress of SAMs in iPSCs, detailing the molecular structure design, deposition methods, and their mechanisms in energy level regulation, defect passivation, and interfacial modification. Furthermore, this review explores sequential deposition and Co-assembled monolayers (Co-SAMs) strategies to further enhance device performance. Finally, the challenges and future directions of SAMs technology are discussed, including large-area fabrication, long-term stability improvement, cost reduction, and the design of novel SAMs molecules. SAMs technology is expected to promote the high-efficiency, stable, and low-cost commercialization of iPSCs, contributing to the sustainable development of clean energy.
