Electronic operation of perovskite single crystal devices unraveled

We have illustrated that the perovskite MAPbI3 detector shows outstanding X-ray imaging performance even after 1.5 years of storage in ambient condition. Further improvements of the surface passivation of the pixelated X-ray imaging detector are still needed. This research highlights the great potential of perovskite technology to take X-ray imaging to the next step towards a new era in medical imaging.
