我们报道了用于Pt/Ti对电极的钛网的NaOH水热处理和HF后处理提高了染料敏化太阳能电池的效率。高性能铂纳米颗粒已经被喷涂到Ti网上以形成用于在低温(120°C)下使用真空热分解方法的大面积柔性DSSC中使用的对电极。Pt/Ti对电极具有较低的电荷转移电阻(57.52Ω cm ~ 2,有效面积80 cm ~ 2)和较高的电催化活性。研究了经NaOH处理后的钛网经不同HF处理时间后的Pt/Ti对电极的光伏性能和电阻。大面积(80 cm 2)柔性DSSC在室外测量的55 mWcm − 2自然光强度下的效率达到6.17%。
We report that NaOH hydrothermal treatment and HF post-treatment of the titanium mesh for the Pt/Ti counter electrode improved the efficiency of dye-sensitized solar cells. High performance platinum nanoparticles have been sprayed onto Ti meshes to form counter electrodes for use in large-area flexible DSSCs using a vacuum thermal decomposition method at low temperature (120°C). The obtained Pt/Ti counter electrode shows low charge-transfer resistance (57.52Ωcm2with active area of 80cm2) and high electrocatalytic activity for the I3−/I−redox reaction. The photovoltaic properties and resistances of Pt/Ti counter electrodes with different HF post-treatment times of the NaOH treated Ti meshes have been investigated. The efficiency of the large-area (80cm2) flexible DSSC reaches 6.17% under irradiation with a natural light intensity of 55mWcm−2measured outdoors.
