Abstract:By means of density functional theory computations, we comprehensively investigated the stability and electronic properties of the hybrid CH3NH3PbI3 (methylammonium lead iodide, MAPI)/graphene heterojunctions, where the MAPI layer was adopted with MAT (methylammonium iodide)-terminations. Our computations demonstrated that the sigma-pi interfacial interactions make the contact very stable, and such interactions lead to charge redistribution and concomitant internal electric field in the interface, which is beneficial for the electron-hole separation.
