Abstract

The defects at perovskite film surface could be passivated effectively using a derivative of polyhedral oligomeric silsesquioxane with an amino-group (NH₂-POSS). The extremely low trap-state energy level (0.045 eV) was obtained by temperature-dependent admittance measurements. Both stability and efficiency in devices have been approved.
