Abstract :
In this work, we demonstrated an inverted planar heterojunction organic photovoltaic (OPV) device with boron subphthalocyanine (SubPc) material. In this device, ZnO was used as the electron extraction layer, which was coated with ethoxylated polyethylenimine (PEIE) for smoothen the ZnO surface. Open circuit voltage of this OPV can be as high as 1.36 eV, which is close to the theoretical limit of SubPc-based device.
