Method and device for suppressing current drift of perovskite photodetector with alternating current |
| abstract |
The invention belongs to the technical field of semiconductor photodetectors, and discloses a method and a device for suppressing the current drift of a perovskite photodetector by alternating current, wherein the method is specifically to inject a perovskite functional layer into a perovskite photodetector The bias voltage applied at both ends is controlled as an alternating current, and the alternating current is used to weaken the ion migration phenomenon in the perovskite material in the perovskite functional layer, thereby suppressing the current drift when the perovskite photodetector is working. The corresponding device includes an AC power supply for finally applying an alternating current to both ends of the perovskite functional layer. The alternating current is used as a bias voltage of the perovskite functional layer to weaken the ion migration phenomenon in the perovskite material in the perovskite functional layer, and can suppresses current drift during device operation. The present invention controls the bias voltage applied when the perovskite photodetector is working to be alternating current, and uses the alternating current to weaken the phenomenon of ion migration, thereby effectively suppressing the current drift problem when the perovskite photodetector is working. |
