Description

Sung-Doo Baek and colleagues solve in 2026 the streaky film problem that blocks large perovskite light panels. Perovskite inks dry unevenly at scale, leaving rings and patchy crystals that waste light. Their recipe blends three solvents and pairs open-air blade coating with vacuum drying to steer how the film forms.

Flow inside the wet film spreads material evenly, while the solvent mix controls when crystals start and grow. Finished films showed smoother coverage, fewer defects, and stronger light output. Near-infrared panels kept high efficiency as area grew from small test cells to a device large enough for vein imaging. A working vein viewer built from the big panel shows the method in action.
