Abstract
A multiple-coordination framework is constructed by the coordination of choline chloride with negatively/positively charged defects in devices. A charge neutralized passivation network is formed and charge extraction between layers is enhanced. A high efficiency of 17.06% for CsPbI 2 Br PSCs is obtained.
