摘要/Abstract

摘要： 通过对比FeS2颗粒两种形貌的催化活性及在染料敏化太阳能电池(DSSCs)上的表现，选择出性能更高的FeS2颗粒。通过水热法和热注入法合成了立方体和球状高纯度FeS2，将FeS2制备成对电极(CEs)并组装在染料敏化太阳能电池上。通过测试电池的光电转化效率及对电极的催化活性，发现球状FeS2颗粒有更高的催化活性，基于球状FeS2 CEs的电池也获得了更高的光电转化效率。在100 mW•cm−2 (AM 1.5) 强度的模拟光源下, 基于立方体和球状高纯度FeS2对电极的染料敏化太阳能电池分别获得了高达4.55%和5.69%的光电转化效率。

Abstract: By comparing the catalytic activity of two morphology FeS2 particles and its performance in dye-sensitized solar cells(DSSCs), FeS2 particles with higher performance are selected. Cubic and spherical high purity FeS2 are synthesized by hydrothermal method and hot-injection method. FeS2 counter electrodes(CEs) are prepared and assembled on DSSC. By measuring the photoelectric conversion efficiency of battery and catalytic characteristic of CEs, it is found that the spherical FeS2 particles show higher catalytic activity, and the battery based on spherical FeS2 CEs present a higher photoelectric conversion efficiency. Under simulated solar light irradiation with intensity of 100 mW•cm−2 (AM 1.5), the DSSCs based on the cube and sphere high purity FeS2 CEs achieve a photoelectric conversion efficiency of 4.55% and 5.69%, respectively.
