N2 - By using 2-(4-biphenylyl)-5-phenyl-1,3,4-oxadiazole (PBD) as an exciton blocking layer (EBL) at the organic/cathode interface of conventional copper phthalocyanine/fullerene (CuPc/C60) organic phtovoltaic (OPV) cells, a more efficient OPV cell was fabricated. The electrical characteristics of OPV cells with and without PBD as an exciton blocking layer were studied. The results showed that the power conversion efficiency (η) was increased from 0.7% to 1.58%. Also, the dependency of the power conversion efficiency on the absorption spectra of exciton blocking layer (PBD) in OPV cells was investigated, and it showed that the inserted PBD has almost no effect on the visible light absorption of the OPV cell. Hence, the improved photovoltaic performance is ascribed to a more efficient charge carrier transport balance, leading to more effective exciton separation.
