Abstract :
An efficient organic photovoltaic devices (OPVs) have been realized by using a new amorphous absorption material, bis(4-(N-(l-naphthyl)phenylamino) phenyl)fumaronitrile (NPAFN). NPAFN exhibits a hole mobility of 0.07 cm2/Vs as determined by the thin-film transistor. The structure of double-heterojunction OPV, ITO/NPAFN/fulerene/bathocuproine/Al, shows high performance with open circuit voltage of 0.98 V, short current density of 3.72 mA/cm2, and power conversion efficiency of 1.72% under air-mass (AM) 1.5 G illumination at an light intensity of 100 mW/cm2.
