Abstract
Abstract The coffee‐ring effect, caused by uneven deposition of colloidal particles in perovskite precursor solutions, leads to poor uniformity in perovskite films prepared through large‐area printing. In this work, the surface of SnO 2 is roughened to construct a Wenzel model, successfully achieving a super‐hydrophilic interface. This modification significantly accelerates the spreading of the perovskite precursor solution, reducing the response delay time of perovskite colloidal particles during the printing process. Additionally, the micro‐spherical depression structure on the SnO 2 surface effectively inhibits the migration of colloidal particles toward the edges of liquid film, trapping perovskite…
