Abstract Among renewable energies, using photovoltaic systems to convert solar energy into electricity without noise, toxin production and release of greenhouse gases has become increasingly important. These panels are diversely used on building roofs in urban areas, which exposes them to problems such as rapid deposition of dust and pollution that reduces light transmittance and cell efficiency. The present study aimed to enhance the self-cleaning ability of the glass surface of the solar cells. Therefore, titanium dioxide (TiO2) coating was applied for ultraviolet light section. TiO2 doped with nitrogen (N-TiO2) and four metals including copper (Cu-TiO2), cobalt (Co-TiO2), iron (Fe-TiO2) and silver (Ag-TiO2) coating were applied for visible light section. The surfaces were prepared by nanosol/dip-coating method. Using an ultraviolet–visible (UV–Vis) spectrometer, self-cleaning of glass surface, removal of methylene blue (MB) and light transmittance was investigated. Moreover, the prepared samples were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM) and Atomic force microscopy (AFM) analysis.

自洁玻璃表面涂层提高亚甲基蓝去除效率的有效操作参数研究 在太阳能电池中的应用

摘要 在可再生能源中，利用光伏系统将太阳能转化为电能，无噪音、无毒、无温室气体排放已变得越来越重要。这些面板被广泛用于城市地区的建筑屋顶，这使它们面临诸如灰尘快速沉积和污染等问题，从而降低透光率和电池效率。本研究旨在提高太阳能电池玻璃表面的自清洁能力。因此，紫外光部分采用了二氧化钛（TiO2）涂层。TiO2 掺杂氮 (N-TiO2) 和四种金属，包括铜 (Cu-TiO2)、钴 (Co-TiO2)、铁 (Fe-TiO2) 和银 (Ag-TiO2) 涂层用于可见光部分。表面通过纳米溶胶/浸涂法制备。使用紫外-可见 (UV-Vis) 光谱仪，研究了玻璃表面的自清洁、亚甲蓝 (MB) 的去除和透光率。此外，制备的样品通过 X 射线衍射 (XRD)、傅里叶变换红外光谱 (FT-IR)、扫描电子显微镜 (SEM) 和原子力显微镜 (AFM) 分析进行表征。
