«These results address a long - standing problem not just for the perovskite family, but relevant to a large group of materials where edges and surface states generally degrade the optoelectronic properties, which can now be chemically designed and engineered to
achieve efficient flow of charge and energy leading to high - efficiency optoelectronic devices,» said Aditya Mohite, who leads the perovskite program in the Material Synthesis and Integrated devices group at Los Alamos.
