In this experimental strategy, we report a new cost-effective platinum-free counter electrode (CE) for dye-sensitized solar cells (DSSC). The counter electrode was made by functionally fixing ${\text{SnS}}_2$ nanoflakes on functionalized multi-walled carbon nanotubes $(f-\text{MWCNTs})$ and single-crystal reduced graphene oxide (RGO). The efficiency of the ${\text{SnS}}_2@f-\text{MWCNTs}@\text{RGO}$ nanohybrid shows significant electrocatalytic activity for the reduction of triiodide. The excellent chemical stability corresponds to the synergistic effect of ${\text{SnS}}_2(\text{NFs})$ fixed on $f-\text{MWCNTs}$, while the conductivity of RGO is very high. In addition, the ${\text{SnS}}_2@f-\text{MWCNTs}@\text{RGO}$ nanocomposite as the counter electrode in DSSCs showed a surprising efficiency of the triiodide/iodide redox pair of 8.7%. It can be expected that this new form of electrode manufacturing will provide a new horizon for research in energy-based applications.

在此实验策略中，我们报告了一种用于染料敏化太阳能电池（DSSC）的新型经济高效的无铂对电极（CE）。对电极通过功能固定来制造${\text{锡}}_2$ 功能化的多壁碳纳米管上的纳米薄片 $（F-\text{碳纳米管}）$和单晶还原氧化石墨烯（RGO）。效率${\text{锡}}_2@F-\text{碳纳米管}@\text{RGO}$纳米杂化物对三碘化物的还原显示出显着的电催化活性。优异的化学稳定性对应于${\text{锡}}_2（\text{神经纤维}）$ 固定在 $F-\text{碳纳米管}$，而RGO的电导率很高。除此之外${\text{锡}}_2@F-\text{碳纳米管}@\text{RGO}$纳米复合材料作为DSSC中的对电极，其三碘化物/碘化物氧化还原对的效率高达8.7％。可以预期，这种新型的电极制造形式将为基于能量的应用研究提供新的视野。
