摘　　要：Additives and iodine(I_2) are used to modify the binary room temperature ionic liquid(RTIL) electrolyte to enhance the photovoltaic performance of dye-sensitized solar cells(DSSCs). The short-circuit current density(JSC) of 17.89 m A/ cm2, open circuit voltage(VOC) of 0.71 V and fill factor(FF) of 0.50 are achieved in the optimal device. An average photoelectric conversion efficiency(PCE) of 6.35% is achieved by optimization, which is over two times larger than that of the parent device before optimization(2.06%), while the maximum PCE can reach up to 6.63%.
