Multifunctional Additive Engineering Enables Controlled Crystallization for Scalable Perovskite Solar Cells
Scalable fabrication of high‐quality perovskite films is essential for the commercialization of perovskite solar cells (PSCs). However, the uncontrolled crystallization kinetics during slot‐die coating often result in large‐area perovskite film with high defect density and unfortunate spatial uniformity. Herein, we...
