Long-term Stability and Dark Recovery Assessment of Perovskite Solar Cells
Perovskite solar cells are a new class of solar devices that have the potential to revolutionize the solar industry in the near future. However, one of the most limiting obstacles of this emerging technology is related to their stability: perovskites are prone to degradation under environmental conditions, i.e., oxygen and humidity, and operational conditions, i.e., light and bias. Each of these stimuli can lead to the loss of performance and the long-term stability of the device. Light may be able to introduce ionic defects, which are prone to migrate in the perovskite devices. On the other hand, photo-induced performance-loss can be entirely or partly recovered in the dark. In this proposal, we will aim to investigate changes in the dynamic response of devices due to light-induced defect formation as well as the impact of dark recovery cycles on the operational stability of solar cell devices.
