Passivation Moisture penetration through surface defects into the active layer is responsible for degradation of device performance in humid environments. In article no. 1800327 , Zhijie Wang, Huiqiong Zhou, Shengchun Qu, and coworkers show that the interaction of the perovskite material with DRCN5T increases the durability of the device in ambient conditions, because the passivated defect sites on the film surface suppresses the transit of moisture or oxygen through the defects.
