As perovskite solar cells (PSCs) move toward commercialization, their extreme sensitivity to ambient moisture remains a major barrier to scalable, low-cost manufacturing. Now, researchers from Xidian University, led by Prof. Weidong Zhu and Prof. Chunfu Zhang, have developed a self-buffered molecular migration strategy that enables moisture-resistant, ambient-air crystallization of perovskite films—achieving record efficiencies without the need for strict humidity control.
