Doping and capping promise perovskite stability
Scientists demonstrated two new approaches to improving the stability of perovskite solar cells. By both incorporating rubidium into the structure of the perovskite, and adding a film of two-dimensional perovskite as a capping layer, they were able to demonstrate a significant reduction in the cell’s sensitivity to moisture. The group says its research will open up new routes to improved performance and stability in perovskite PV.
