摘要：

In this study, we fabricated and characterized an organic photovoltaic (OPV) device with a pyromellitic dianhydride (PMDA)/lithium fluoride (LiF) cathode interfacial layer between poly(3-hexylthiophene-2,5-diyl)(P3HT)+[6,6]-phenyl C-61 butyric acid methyl ester (PCBM) and Al. Compared to the OPV device with a LiF-only cathode interfacial layer having a power conversion efficiency (PCE) of 2.7%, the OPV device with the bilayer cathode interfacial structure [PMDA (0.3 nm)/LiF (0.7 nm)] exhibited a reduced resistance and a PCE value enhanced to 3.9% under an illumination condition of 100 mW cm(-2) (AM1.5). The observed improvement of the OPV characteristics was attributed to the reduced leakage current of the device by the bilayer cathode interfacial layer.
