摘　　要：研究了不同溶剂和不同对电极对I3-的还原电位和染料敏化太阳能电池的开路电压的影响。在I3-/I-的离子浓度和染料敏化TiO2膜性能相同的情况下,能使I3-在较高的电位下就能还原的对电极溶剂有较高的开路电压。相对于Pt对电极,用石墨作对电极时有较高的开路电压,这是由于小电流时I3-/I-在石墨表面的还原反应过电位要比在Pt表面小。The influence of different resolvents and different counter electrodes to the deoxidize potential of I3^ - and the open-circuit voltage （ Voc ） of dye-sensitized solar cells （DSSC） were researched. On the condition of the same concentration of I3 ^-/I^- and the same dye-sensitized TiO2 film electrode, if the resolvents are different the one in which with higher I3^ - deoxidize potential on counter electrode has a higher open-circuit voltage. The use of graphite counter electrode results to higher Voc compared with Pt counter electrode because of the little deoxidize overpotential of I3^ - on graphite electrode compared with which on the Pt electrode at little current density.
