Scalable Fabrication of Methylammonium-Free Wide-Bandgap Perovskite Solar Cells by Blade Coating in Ambient Air

Scalable Fabrication of Methylammonium-Free Wide-Bandgap Perovskite Solar Cells by Blade Coating in Ambient Air

Highlights 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 per...
