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.
研究瞭不同溶劑和不同對電極對I3-的還原電位和染料敏化太暘能電池的開路電壓的影響.在I3- /I-的離子濃度和染料敏化TiO2膜性能相同的情況下,能使I3-在較高的電位下就能還原的對電極溶劑有較高的開路電壓.相對于Pt對電極,用石墨作對電極時有較高的開路電壓,這是由于小電流時I3-/I-在石墨錶麵的還原反應過電位要比在Pt錶麵小.

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.
