In the quest for finding alternative solar energy conversation devices in place of expensive silicon photovoltaic cells, organic photovoltaic (OPV) cells using the mixture of conjugated polymeric materials and acceptors have been proving themselves the front runner. In this paper, two novel fullerene derivatives used as electron acceptors were synthesized through 1, 3-dipolar cycloaddition. The new synthesized fullerene derivatives showed good solubility in common organic solvents and the synthetic products were characterized by 1H NMR, 13C NMR and FAB-Mass. Photovoltaic devices were fabricated using the traditional configuration as follows: ITO/ PEDOT: PSS/ active layer/ LiF/ Al. The weight ratios of the electron donor to the acceptor in the active layer were 1:0.5, 1:0.7 and 1:1. We have found that in the case of the two novel synthesized fullerene derivatives, abbreviated as p-HOPF and o-HOPF, substituent groups onto C60 core have position effects on the characterization of fullerene derivatives and on the efficiency of OPV devices.
