Phys.org  June 24, 2024 Perovskite photovoltaics have been shown to recover, or heal, after radiation damage. A team of researchers in the US (National Renewable Energy Laboratory (NREL), Rochester Institute of Technology, North Texas University, University of North Carolina, NASA Glenn Research Center, Cleveland, OH, University of Oklahoma, University of Buffalo) deconvolved the effects of radiation based on different energy loss mechanisms from incident protons which induce defects or can promote efficiency recovery. They designed a dual dose experiment first exposed devices to low-energy protons efficient in creating atomic displacements and then irradiated with high-energy protons that interacted differently.
