Figure 1. (A) I-V response of pristine MAPbI3 films with voltage applied from 0 to 1.5 V, (B) Transient dark current response of pristine MAPbI3 films. (C) I-V response after 24 h exposure at 85 °C. (D) Transient dark current response after 24 h exposure at 85 °C, where no ionic response is detectable after degradation.
