Abstract

The electronic structure of a bi‐layer hole extraction contact consisting of nickel oxide (NiO_x) and molybdenum trioxide (MoO₃) is determined via ultraviolet and X‐ray photoemission spectroscopy. The bi‐layer presents ideal energetics for the extraction of holes and suppression of carrier recombination at the interface. The application of the NiO_x/MoO₃ bi‐layer as the anode of organic bulk heterojunction solar cells based on PCDTBT/PC₇₁BM leads to improved device performance, which is explained by an intricate charge transfer process across the interface.
