Tin oxide is a widely employed charge-transport material for high-performance perovskite solar cells. In this work, a graded redox interfacial modifier, cobalt hexammine sulfamate, is found to improve the properties of tin oxide. It reduces the interfacial defect density and improving the crystallinity of the perovskite. The resultant perovskite solar cells show excellent stability under elevated temperatures.
