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