Prof. Noh and his colleagues​ have recently devised an alternative approach for creating solar cells that combine 2-D and 3-D halide perovskites. This approach, outlined in a paper published in​ Nature Energy, could help to simultaneously improve both the efficiency and long-term stability of these cells.
