Three quinquethiophene derivatives with different end groups of octyl 2-cyanoacetate (DCAO5T), 3-ethylrhodanine (DERHD5T) and 2H-indene-1,3-dione (DIN5T) are synthesized in order to obtain higher open circuit voltage (Voc) than their septithiophene analogs. The photovoltaic performance of these three molecules as donors and fullerene derivatives as the acceptors in bulk heterojunction solar cells are studied by using the simple solution spin-coating fabrication process. Among them, DERHD5T shows Voc as high as 1.08 volt and power conversion efficiency of 4.63% under AM 1.5G irradiation (100 mW cm2). The reasons for the high Voc were investigated by the theoretical simulations and consistent results have been obtained in comparison with experimental measurements.
