In the quest for finding alternative solar energy generation 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, a novel fullerene derivative used as electron acceptor was synthesized via a carbene intermediate and characterized. The new synthesized fullerene derivative showed good solubility in common organic solvents and the synthetic product was characterized by 1H NMR, 13C NMR and FT-IR. Photovoltaic devices were fabricated using the 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. The open-circuit voltage (Voc) of the fabricated devices was found to be higher than that of devices based on C60 because the LUMO energy level of the new fullerene derivative was higher than that of C60. Synthesis of the fullerene derivative and characteristics of the fabricated solar cells will be presented.
