    An interface engineering process to deploy graphene film as the anode in poly(3‐hexylthiophene‐2,5‐diyl):6,6‐phenyl C61 butyric acid methyl ester (P3HT:PCBM)‐based polymer solar cells is demonstrated. By modifying the interface between the graphene anode and the photoactive layer with MoO3 and poly(3,4‐ethylenedioythiophene):poly(styrenesulfonate) (PEDOT:PSS), the power conversion efficiency of the solar cells reaches ≈83.3% of control devices that use an indium tin oxide (ITO) anode.
