title: Radiation Hardness and Self-Healing of Perovskite Solar Cells.
abstract: The radiation hardness of CH3NH3PbI3-based solar cells is evaluated from in situ measurements during high-energy proton irradiation. These organic-inorganic perovskites exhibit radiation hardness and withstand proton doses that exceed the damage threshold of crystalline silicon by almost 3 orders of magnitude. Moreover, after termination of the proton irradiation, a self-healing process of the solar cells commences.
