In this study, poly(3,3-dibenzyl-3,4-dihydro-2-thieno[3,4-][1,4]dioxepine)/platinum composite films (PProDOT-Bz₂/Pt) were used as counter electrodes (CEs) in dye-sensitized solar cells (DSSCs). The composite films were prepared on fluorine-doped tin oxide (FTO) glass by radio frequency (RF) sputtering to deposit platinum (Pt) for 30 s. Afterwards, PProDOT-Bz₂ was deposited on the Pt⁻FTO glass via electrochemical polymerization. The electron transfer process of DSSCs was investigated using electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The DSSCs with 0.05 C/cm² PProDOT-Bz₂-Pt composite films showed an open circuit voltage () of 0.70 V, a short-circuit current density () of 7.27 mA/cm², and a fill factor (F.F.) of 68.74%. This corresponded to a photovoltaic conversion efficiency (η) of 3.50% under a light intensity of 100 mW/cm².
在本研究中，聚（3,3-二苄基-3,4-二氢-2-噻吩并[3,4-][1,4]二氧杂环庚烷）/铂复合薄膜（PProDOT-Bz₂/Pt）被用作染料敏化太阳能电池（DSSC）的对电极（CE）。通过射频（RF）溅射在氟掺杂氧化锡（FTO）玻璃上制备复合薄膜，沉积铂（Pt）30秒。之后，通过电化学聚合将PProDOT-Bz₂沉积在Pt⁻FTO玻璃上。使用电化学阻抗谱（EIS）和循环伏安法（CV）研究了DSSC的电子转移过程。具有0.05 C/cm² PProDOT-Bz₂-Pt复合薄膜的DSSC的开路电压（）为0.70 V，短路电流密度（）为7.27 mA/cm²，填充因子（F.F.）为68.74%。这对应于在100 mW/cm²光强下3.50%的光伏转换效率（η）。
