| 摘 要： | 采用水热法合成四硫化三钴（Co3S4）催化材料，并利用球磨和喷涂技术将其制备成对电极，结合新型无碘电解液Co2+/Co3+用于染料敏化太阳电池（dye-sensitized solar cells，简称DSCs）来研究其光电性能。测试结果显示，基于Co3S4对电极，DSCs的能量转化效率（power conversion efficiency，简称PCE）只有6.06%，远远低于Pt对电极（8.05%）。为了提高Co3S4的催化能力，采用静电纺丝技术制备碳纳米纤维（electrospun carbon nanofibers，简称ECs），结合水热法制备出不同负载量的碳纳米纤维负载四硫化三钴（Co3S4/ECs）复合催化材料用于对电极，结果表明，Co3S4/ECs的PCE最高可达（8.22±0.08）%，优于Pt对电极。

| Abstract: | Cobaltosic sulfide (Co3S4) was synthesized by hydrothermal synthesis method. Combining the ball grinding mill and spray method, Co3S4 was prepared into counter electrode (CE) and fabricated dye-sensitized solar cells (DSCs) with the novel electrolyte Co2+/Co3+. The power conversion efficiency (PCE) obtained by the DSCs based on the pure Co3S4 CE was only 6.06%, which was much smaller than that of Pt (8.05%). To improve the catalytic activity of pure Co3S4, electrospun carbon nanofibers (ECs) were fabricated by the electrospun method and the composite of ECs supported cobaltosic sulfide (Co3S4/ECs) was synthesized by hydrothermal synthesis method. And the DSCs based on Co3S4/ECs CE achieved a high PCE of (8.22±0.08)%, which was a little higher than that of Pt (8.05%). |
