摘要：The effect of exciton blocking layer (EBL) on the performance of bilayer copper pthalocyanine (CuPc)/fullerene (C60) photovoltaic devices is studied and the results are presented here. CuPc and C60 are the electron donor and acceptor respectively. The application of EBL enhances the fill factor (FF) and short circuit current (Jsc), which results in the enhancement of the overall efficiency of the devices. Bathocuproine (BCP) and bathophenanlthroline (BPhen) are used as the EBL materials in these studies. With respect to the standard device (device containing no EBL), an enhancement of ~ 48 times in efficiency is observed for the device containing BCP. The application of BPhen in place of BCP enhances further the efficiency by ~ 70 %, which is attributed to better electron transportation through BPhen.
