大面积有机-无机杂化钙钛矿薄膜及其光伏应用研究进展OA北大核心CSTPCD

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.
