摘要
有机-无机杂化钙钛矿太阳能电池具有制备成本低、光电转换效率(Photoelectric Conversion Efficiency,PCE)高的巨大优势,显示出广阔的商业化前景.经过十几年的深入研究,钙钛矿太阳能电池(Perovskite Solar Cells,PSCs)的实验室器件(＜1 cm2)、大面积器件(1～10 cm2)、迷你模组级器件(10～800 cm2)和模组级器件(＞800 cm2)的最高认证PCE已分别提升至26.10％、24.35％、22.40％和18.60％.随着PSCs面积扩大,PCE急剧下降,这主要是因为制备方法的局限性,难以获得高质量的大面积钙钛矿薄膜.实验室器件常采用的旋涂法难以应用到实际生产中,目前大面积钙钛矿薄膜的制备方法主要有刮涂法和狭缝涂布法,但其存在薄膜成核结晶过程难以精确控制等问题.本文从大面积有机-无机杂化钙钛矿薄膜的制备方法入手,介绍了大面积钙钛矿层成膜机制及薄膜质量提升策略.最后,对未来高PCE、高稳定性的大面积PSCs的制备技术和应用进行了展望,旨在对高性能的大面积PSCs研究提供有益参考.
Abstract
Recently,organic-inorganic hybrid perovskite solar cells have demonstrated a broad commercial prospect due to their high photoelectric conversion efficiency(PCE)and low fabricating costs.During the past decades,the highest reported PCE of small-area(＜1 cm2)perovskite solar cells(PSCs)rose to 26.10％,and those of large-area(1-10 cm2),mini-module level(10-800 cm2)and module level(＞800 cm2)PSCs increased to 24.35％,22.40％and 18.60％,respectively.The performance of PSCs decreases dramatically with the area increasing due to limitation of the deposition method and the poor quality of large-area perovskite films.Spin-coating method is not suitable for actual industrial production,while the scalable deposition methods including blade-coating and slot-die coating still face the difficulty of precisely controlling nucleation and crystallization of the perovskite films with large area.This review summarized preparation methods of large-area perovskite films,and discussed the film-forming mechanism and strategies for high-quality perovskite films.Finally,relevant outlooks on technologies and applications for large-area PSCs with high performances and stabilities were analyzed.This review is expected to provide insights on the research of large-area PSCs with high performance.
