A first-principles prediction on the “healing effect” of graphene preventing carrier trapping near the surface of metal halide perovskites
We herein report that surface modification of metal halide perovskites using graphene would be beneficial to improving the energy conversion efficiencies of perovskite solar cells. The present first-principles calculations on MAPbI(3) with a single vacancy created by removing either I, Pb or MA show...
