摘要：

In this study, we investigated the high fill factor (FF) and high power conversion efficiency (PCE) of organic photovoltaic (OPV) cells using a dual hole-transporting layer (HTL) of vanadium oxide (V2O5)/copper phthalocyanine (CuPc) as a buffer layer. The OPV cell configuration consists of indium tin oxide (ITO)/V2O5/CuPc/poly(3-hexylthiophene) (P3HT): phenyl C61-butyric acid methylester (PCBM)/LiF/Al. The FF and PCE of the device with a V2O5/CuPc buffer layer are approximately threefold and tenfold, respectively, greater than those of a conventional device without the buffer layer. The FF and PCE of the device are 62.2 and 2.11%, respectively, under a simulated AM1.5G illumination of 100 mW/cm(2). The increased PCE and FF of the device are obtained using a V2O5/CuPc buffer layer, which is attributed to the stepwise hole-transporting configuration and the increased optical absorption from the anode.
