摘要

The electronic structure of a bi-layer hole extraction contact consisting of nickel oxide (NiO_x) and molybdenum trioxide (MoO_3) 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/MoO_3 bi-layer as the anode of organic bulk heterojunction solar cells based on PCDTBT/PC_(71) BM leads to improved device performance, which is explained by an intricate charge transfer process across the interface.
