摘　　要：S114TFSI与S221I离子液体是一种新型的室温离子液体,其高沸点,不易挥发等优点使其能应用于染料敏化太阳电池中。测定了不同膜厚的TiO2光电极,不同体积比的S114TFSI与S221I组成的电解质体系以及添加剂TBP与LiI的加入对太阳电池性能的影响。实验表明,制取10mm左右厚度的TiO2电极,选取S114TFSI与S221I体积比为1∶1的电解质,加入0.5mol/L的TBP,0.2mol/L的LiI能提高电池性能。S114TFSI and S221I ionic liquid is a kind of new room temperature ionic liquid, and has the advantages of high boiling point and less volatility , which make it capable of application in the Dye-sensitized solar cells. The performances of dye-sensitized solar cells with different thicknesses of electrodes, different volume percentages of S114TFSI/S221I and additions of additive such as TBP or LiI were measured. The tests show that the maximizing condition of the dye-sensitized solar cells is that the thickness of electrodes is 10 mm, the volume percentage of S221I is 50% and the concentrations of TBP and LiI are 0.5 mol/L and 0.2 mol/L.
