In this paper, the prospects of iron oxide films and their sulfidation for dye-sensitized solar cells (DSSC) are reviewed. Iron oxide thin films were prepared by hollow cathode plasma jet (HCPJ) sputtering, with an admixture of oxygen in the argon working gas and with an iron nozzle as the sputtering target. The discharge was powered by a constant current source in continuous mode and by a constant voltage source in pulsed mode. Plasma composition was measured by an energy-resolved mass spectrometer. Moreover, secondary electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), absorption and Raman spectra of the films are presented. Strong correlation between the color of the iron oxide film and its phase composition was revealed. Iron oxide films were sulfided at 350 °C. A relatively clean pyrite phase was obtained from the magnetite, while the marcasite with admixture of the pyrite phase was obtained from the hematite. Low influence of sulfidation on the films' microstructure was demonstrated.
本文综述了氧化铁薄膜及其硫化处理在染料敏化太阳能电池（DSSC）中的应用前景。采用空心阴极等离子体射流（HCPJ）溅射法制备氧化铁薄膜，以铁喷嘴为溅射靶材，在氩气工作气体中混入氧气。放电由连续模式下的恒流源和脉冲模式下的恒压源供电。用能量分辨质谱仪测量等离子体成分。此外，还给出了薄膜的二次电子显微镜（SEM）、能量色散X射线光谱（EDX）、吸收光谱和拉曼光谱。揭示了氧化铁薄膜颜色与其相组成之间的强相关性。氧化铁薄膜在350℃下进行硫化处理。磁铁矿硫化后得到相对纯净的黄铁矿相，赤铁矿硫化后得到含有黄铁矿相混合物的白铁矿。结果表明硫化处理对薄膜微观结构的影响较小。
