In this paper, we chemically synthesized interconnected nanoflake-like CdS thin films for photoelectrochemical solar cell applications and subsequently irradiated them with electron beam irradiation at various doses of irradiation. The as-synthesized and irradiated samples were characterized by means of X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), and electrochemical measurements. XRD and XPS results confirmed the formation of CdS with a hexagonal crystal structure. FE-SEM and HR-TEM studies confirmed the photoelectrochemical performance, which was dependent on the surface morphology. The calculated values for efficiency demonstrated an outstanding photoelectrochemical performance with a fill factor of 0.38 and efficiency of 3.06% at 30 kGy. The high photoelectrochemical performance may be due to the interconnected nanoflake-like nanostructure and higher active surface area of the CdS samples. These results show that the electron beam irradiation is capable as an electrode for photoelectrochemical solar cells.
在本文中，我们通过化学合成方法制备了具有互联纳米片状结构的 CdS 薄膜，用于光电化学太阳能电池，并进一步用电子束辐照对其进行了不同剂量的辐照处理。通过 X 射线衍射（XRD）、场发射扫描电子显微镜（FE-SEM）、高分辨率透射电子显微镜（HR-TEM）和电化学测量对合成和辐照后的样品进行了表征。XRD 和 XPS 结果证实了具有六方晶体结构的 CdS 的形成。FE-SEM 和 HR-TEM 研究证实了光电化学性能，其取决于表面形态。计算得到的效率值在 30 kGy 时表现出出色的光电化学性能，填充因子为 0.38，效率为 3.06%。高光电化学性能可能归因于 CdS 样品的互联纳米片状结构和更高的活性表面积。这些结果表明，电子束辐照可以作为光电化学太阳能电池的电极。
