采用聚（3,3-二乙基-3,4-二氢- 2h -噻吩-[3,4-b][1,4]二奥塞平）（PProDOT-Et-2）对电极替代塑料染料敏化太阳能电池（DSSC）中的Pt电极。表征了PProDOT-Et-2和溅射pt电极的表面形貌和I-/I-3（-）氧化还原行为，并比较了它们在塑料dsscs中作为对电极的性能。在100 mW cm（-2）的光照下，PProDOT-Et-2对电极制备的电池的转换效率为5.20%，而溅射pt对电极制备的电池的转换效率为5.11%。这种增强归因于PProDOT-Et-2的有效表面积增加和良好的催化性能
A poly(3,3-diethyl-3,4-dihydro-2H-thieno-[3,4-b][1,4]dioxepine) (PProDOT-Et-2) counter electrode was incorporated in a plastic dye-sensitized solar cell (DSSC) to substitute for Pt electrode. The surface morphology and I-/I-3(-) redox behaviors based on PProDOT-Et-2 and sputtered-Pt electrodes were characterized, and their performances as counter electrodes in the plastic-DSSCs were compared. Cells fabricated with a PProDOT-Et-2 counter electrode showed a higher conversion efficiency of 5.20% compared with cell fabricated with sputtered-Pt (5.11%) electrodes under the illumination of 100 mW cm(-2). This enhancement was attributed to the increase in the effective surface area and good catalytic properties of PProDOT-Et-2 for
