NPAFN exhibits a hole mobility of 0.07 cm 2/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.Amorphous absorption material; Carrier mobility; Electron donor; NPAFN; Organic photovoltaic devices[SDGs]SDG7Absorption material; Amorphous molecular materials; Double-heterojunction; Electron donor; Light intensity; NPAFN; Organic photovoltaic devices; Power conversion efficiencies; Absorption; Conversion efficiency; Heterojunctions; Hole mobility; Open circuit voltage; Thin film transistors; Photovoltaic effectsconference paper10.1109/AOM.2010.57136022-s2.0-79952858771https://www.scopus.com/inward/record.uri?eid=2-s2.0-79952858771&doi=10.1109%2fAOM.2010.5713602&partnerID=40&md5=19f9befddba2987fb8deeb328ef839b7
