黄铁矿（FeS2）具有优良的电催化性能，是染料敏化太阳能电池（DSSC）对电极材料中最有前途的材料之一。采用水热法合成了高纯度的FeS2粉体，并研究了NaOH的加入对FeS2晶粒尺寸和电催化活性的影响。随着NaOH的加入，FeS2颗粒尺寸减小，FeS2 CEs的电催化活性和DSSC性能显著提高。在强度为100 mW cm−2（AM 1.5）的模拟太阳光照射下，基于添加NaOH的FeS2CEs的DSSC实现了5.78%的功率转换效率。
Iron pyrite (FeS2) has been proved to be one of the most promising materials for counter electrodes (CEs) of dye-sensitized solar cells (DSSCs) due to its excellent electrocatalytic properties. In this report, high purity FeS2powders were synthesized through hydrothermal method, and the effect of NaOH addition on crystal size and electrocatalytic activities of FeS2was investigated. With the addition of NaOH, the size of FeS2particles decreased, and the electrocatalytic activity of the FeS2CEs and the DSSCs performance were improved significantly. Under simulated solar light irradiation with intensity of 100 mW cm−2(AM 1.5), the DSSCs based on FeS2CEs with NaOH addition achieved a power conversion efficiency of 5.78%.
