三种不同的碳基反电极的光催化活性，如电化学频率和界面阻抗进行了研究。采用电泳沉积法制备了石墨烯、单壁碳纳米管和石墨烯-单壁碳纳米管复合材料的染料敏化太阳能电池对电极。我们观察了碳基对电极的光学和电化学性质。具有石墨烯沉积的对电极的DSSC在AM 1.5和1个太阳条件下表现出5.87%的最佳转换效率。它可以用于DSSC的低成本和高通量过程。
Three different carbon-based counter electrodes are investigated in light of catalytic activities such as electrochemical frequencies and interface impedances. We fabricated carbon-based counter electrodes of dye-sensitized solar cells [DSSCs] using graphene, single-walled carbon nanotubes [SWNTs], and graphene-SWNT composites by electrophoretic deposition method. We observed the optical and electrochemical properties of the carbon-based counter electrodes. The DSSC with the graphene-deposited counter electrode demonstrated the best conversion efficiency of 5.87% under AM 1.5 and 1 sun condition. It could be utilized for a low-cost and high-throughput process for DSSCs.
