Scalable Fabrication of Methylammonium‑Free Wide‑Bandgap Perovskite Solar Cells by Blade Coating in Ambient Air (IMAGE)
Caption
- RbI is the most effective in mitigate PbI2 precipitation caused by Pb(SCN)2 while maintaining large grains.
- Rb is kept at the grain boundaries during crystallization and Ostwald ripening, contributes to a slow growth of the grains.
- Wide-bandgap perovskite solar cells with blade-coated perovskite in air achieved a certified power conversion efficiency of 23%, among the highest values reported.
