Scratching the surface of perovskites

(Okinawa Institute of Science and Technology (OIST) Graduate University) Professor Yabing Qi and his team in the Energy Materials and Surface Sciences Unit at OIST, in collaboration with researchers at the University of Pittsburgh, USA, have, for the first time, characterized the structural defects that prompt the movement of ions, destabilizing the perovskite materials. The researchers' findings, published in ACS Nano, may inform future engineering approaches to optimize perovskite solar cells.
