采用原位电聚合法制备了具有一维网络结构的高电催化活性硫化镍/聚苯胺/钛（NiS/PANI/Ti）复合薄膜，并将其作为柔性染料敏化太阳能电池（FDSSCs）的无铂对电极（CE）催化剂。基于NiS/PANI/Ti CE的FDSSC的光电性能为：Jsc = 14.56 mA · cm−2，Voc = 0.743 V，FF = 0.68，对应的η = 7.35%，远高于Pt/Ti CE的光电转换效率（6.24%）。采用扫描电子显微镜（SEM）、能谱仪（EDS）、循环伏安（CV）、电化学阻抗谱（EIS）和Tafel极化曲线等对一维网络结构的NiS/PANI/Ti CE进行了表征。NiS/PANI/Ti CE具有多种功能，即，该电极具有良好的导电性，对碘/三碘的电催化能力强，电荷转移电阻为1.48 ± 0.02 Ω ·cm 2，比Pt/Ti电极（2.25 ± 0.02 Ω ·cm 2）低。利用光电流-光伏特性曲线计算了器件的理论短路电流密度和开路电压。因此，具有一维网络结构的NiS/PANI/Ti电极可以被认为是一种很有前途的高效FDSCs电极。
A novel titanium foil substrate strategy for the synthesis of high electrocatalytic activity nickel sulfide/polyaniline/titanium (NiS/PANI/Ti) composite film with one-dimensional (1D) net-work structure by using an in situ electropolymerization route, and proposed as platinum (Pt)-free counter electrode (CE) catalyst for flexible dye-sensitized solar cells (FDSSCs). The photovoltaic performance of the FDSSC based on the NiS/PANI/Ti CE exhibitsJscof 14.56 mA · cm−2,Vocof 0.743 V,FFof 0.68, and corresponding to theηof 7.35%, much higher photoelectric conversion efficiency than that of Pt/Ti CE (6.24%). The NiS/PANI/Ti CE with 1D net-work structure is characterized by using the scanning electron microscopy (SEM), energy dispersive spectrometer (EDS), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and Tafel polarization plots. The NiS/PANI/Ti CE presents multiple functions, i.e., excellent conductivity, great electrocatalytic ability for iodine/triiodine, and lower charge transfer resistance of 1.48 ± 0.02 Ω · cm2compared to the Pt/Ti electrode (2.25 ± 0.02 Ω · cm2). The photocurrent-photovoltage (J-V) character curves are further used to calculate theoretical short-current densities and open-circuit voltage of the devices. Therefore, the NiS/PANI/Ti CE with 1D net-work structure can be considered as a promising and efficient CE for FDSSCs.
