Almost all carbon-based materials as counter electrode (CE) for dye-sensitized solar cells (DSSCs) with good performance have been identified in previous studies. Unfortunately, the device with fullerene (C60) or its derivative on fluorine doped tin oxide (FTO) substrate prepared by spin-coating was not the case. Our experimental results show that the C60 fabricated by vacuum thermal deposition performs much better than that prepared by spin-coating though the fill factor(FF) and power conversion efficiency(PCE) are still poor. Further improvement has been achieved in this study by trace Pt modifying thermal deposited C60 CE with a device efficiency of 5.78%, comparable to the one with standard Pt CE. This composite CE was obtained by thermal decomposing a small amount of chloroplatinic acid hexahydrate on FTO prior to C60. The trace Pt underneath the C60 film is believed to improve the conductivity of the C60 CE and then the performance of DSSCs.

在先前的研究中，几乎所有具有良好性能的碳基材料都可以用作染料敏化太阳能电池（DSSC）的对电极（CE）。不幸的是，在通过旋涂制备的氟掺杂的氧化锡（FTO）基材上具有富勒烯（C60）或其衍生物的装置并非如此。我们的实验结果表明，尽管填充因子（FF）和功率转换效率（PCE）仍然很差，但是通过真空热沉积法制备的C60的性能要比旋涂法好得多。在这项研究中，通过痕量Pt改性热沉积C60 CE具有5.78％的器件效率，可与标准Pt CE相比，实现了进一步的改进。通过在C60之前在FTO上热分解少量六水合氯铂酸六水合物来获得该复合材料CE。
