• In this paper, a novel electron donor, bis{4-[N-(1-naphthyl)phenylamino]phenyl}fumaronitrile (NPAFN), was demonstrated as a potential for application in high open-circuit voltage (V_{\text{OC}}) organic photovoltaic (OPV) cells. Devices based on NPAFN/C60 heterojunction were firstly manipulated to their optimum optical property by tuning the thickness of C60 without compromising the transport property. With the appropriate thickness of C60, the electrical configuration of the devices was improved when the thickness of NPAFN was less than 6.3 nm. The optimum efficiency was 2.1% with a V_{\text{OC}} of 0.87 V when the thickness of NPAFN was 5 nm. In addition, the increase in V_{\text{OC}} by increasing the thickness of NPAFN was observed and discussed.
